IMX644 Owner’s Manual

Introduction

Thank you for purchasing the Yamaha IMX644 Digital Installation Mixer. In order to take full

advantage of the IMX644 functionality and to ensure trouble-free operation, please read this

owner’s manual carefully before use. After you have read the manual, keep it in a safe place

for reference when needed.

■

Versatile Input/Output Conﬁguration

The IMX644 features an input/output configuration that is ideal

for a wide range of applications: six mono inputs, four stereo in-

puts, two stereo outputs, two mono outputs, and one dedicated

stereo output for recording.

■

16 Memories

Up to 16 sets of mixer settings can be stored in memory and in-

stantly recalled as required. Four of the memories can be directly

recalled via front-panel MEMORY [A] through [D] buttons.

■

Optical Digital I/O

Connecting to compatible devices (CD and DVD players, for ex-

ample) via the optical digital interface allows accurate signal

transfer with no loss of signal quality. The digital input features

a built-in sample rate converter, so there is no need for word

clock synchronization.

■

Powerful Mixing Features

•Parametric EQ

Parametric equalization is provided on all input channels: 3-

band EQ on mono input channels, and 2-band EQ on stereo

input channels.

6-band EQ is provided on all outputs except the recording

output.

• Feedback Suppressor

Feedback suppression is provided on all six mono input

channels.

The Feedback Suppressor provides two stages of feedback

prevention: static ﬁlters that can be set in advance, and

dynamic ﬁlters that self-adjust in real time to control feed-

back.

• Priority for Speciﬁed Voice or Music Sources

The Priority Ducker automatically “ducks” (reduces the vol-

ume of) the background when a signal is applied to a speci-

ﬁed mono input channel, making announcements stand out

for greater intelligibility. All stereo inputs assigned to the

same output channel are reduced to a speciﬁed level when

priority input is detected.

Music Override gives priority to a music source applied to a

speciﬁed stereo input channel. All other stereo inputs

assigned to the same output channel are muted when prior-

ity input is detected.

• Delay

Precise delays can be applied to all outputs to allow time

alignment for a solid sonic image with clear imaging and

optimum overall sound quality throughout the listening

area.

Introduction

IMX644 Owner’s Manual

This unit will operate stably in an environmental temperature of

0–40˚C. If you install this device together with multiple units of

the same device or other devices in an EIA standard rack, the

heat produced by the various devices may raise the ambient tem-

perature inside the rack, resulting in inefficient performance. To

ensure that the heat produced by this device can be dissipated ap-

propriately, please ensure the following conditions when rack-

mounting it.

• If multiple units are mounted in the same rack, leave a 1U

rack space between every two units. Also either leave the

open spaces uncovered or install appropriate ventilating

panels to minimize the possibility of heat buildup.

• When mounting this device together with other heat-pro-

ducing equipment such as power ampliﬁers, leave 1U or

more space between it and other devices. Install a ventila-

tion panel in this vacant space or leave it open to ensure ade-

quate cooling.

•To ensure sufﬁcient airﬂow, leave the rear of the rack open

and position it at least 10 centimeters from walls or other

surfaces. If the rear of the rack can’t be left open, install a

commercially available fan or similar ventilating option to

secure sufﬁcient airﬂow. If you’ve installed a fan kit, there

may be cases in which closing the rear of the rack will pro-

duce a greater cooling effect. Refer to the rack and/or fan

unit manual for details.

■

Connecting the AC Power Cable

CAUTION

• Before connecting the power cable, make sure that the power

switches of all devices are turned OFF.

First connect the supplied power cable to the [AC IN] socket on

the rear panel of the IMX644, then connect the AC plug to an ap-

propriate AC power outlet (make sure the local supply voltage

matches the rated AC voltage of the unit).

■

Powering ON or OFF

CAUTION

•To prevent loud noise bursts from the speakers when power-

ing up the system, turn devices ON in the following order:

audio sources (microphones, CD players, etc.), IMX644, and

ﬁnally power ampliﬁers. Reverse this order when turning the

system off.

Press the [ON] end of the [POWER] switch to

turn the unit ON.

Press the [OFF] end of the [POWER] switch to

turn the unit OFF.

CAUTION

• Rapidly turning the unit ON and OFF in succession can

cause it to malfunction. After turning the unit OFF, wait for

more than 6 seconds before turning it ON again.

The information in this manual deals primarily with setting up

and operating the IMX644 hardware.

■ [MONO INPUT] and [OUTPUT] Con-

nectors (3-pin Euroblock)

Connect external microphones, amplifiers and other devices to

the rear-panel [MONO INPUT] and [OUTPUT] connectors via

cables fitted with the supplied 3-pin Euroblock plugs.

Follow the procedure outlined in this section to attach the Eurob-

lock plugs to the appropriate cables.

Use balanced lines to connect microphones and similar sources

to the [MONO INPUT] connectors. Wire balanced cables as

shown in the diagram below.

When an amplifier to be connected to the OUTPUT connector

has balanced XLR type inputs, wire the connection cable as

shown in the diagram below.

Euroblock Plug Connection

Use the included Euroblock plug (3P) to make connections to the

[MONO INPUT] and [OUTPUT] connectors.

1 Loosen the terminal screws.

NOTE

•A “minus” type screwdriver with a blade width of approxi-

mately 3 millimeters is recommended for Euroblock connec-

tor attachment.

2 Insert the cables.

● Cable preparation

•To prepare the cable for

attachment to a Eurob-

lock connector, strip the

wire as shown in the

illustration, and use

stranded wire to make

connections. With a Euroblock connection, the stranded

wire may be prone to breakage because of metal fatigue

due to the weight of the cable or due to vibration. When

rack-mounting your equipment, use a lacing bar when

possible to bundle and fasten the cables.

• If cables will be fre-

quently connected and

disconnected, as in the

case of a portable instal-

lation, we recommend

that you use ferrules with

insulation sleeves. Use a

ferrule whose conductor

portion has an external diameter of 1.6 mm or less, and a

length of approximately 7 mm (such as the AI0,5-6WH

made by the Phoenix Contact corporation).

CAUTION

• If you use stranded wire, do not tin (plate with solder) the

exposed end.

3 Securely tighten the terminal screws.

Pull the cables (not too strongly) to conﬁrm that they are

securely connected.

4 Connect the Euroblock plug to the IMX644

Euroblock connector.

■ [REMOTE] Connector (RS-232C)

Connect to this connector when controlling the IMX644 from

the IMX644 Manager application or an external AMX/Crestron

controller. Use an RS-232C cross cable for connection.

An external AMX or similar controller can be used to send com-

mands to the IMX644 to recall memories and adjust the level of

individual channels. Refer to page 20 for information on the

available remote control commands.

■ [GPI] Connector (25-pin D-sub)

External GPI (General Purpose Interface) control devices can be

connected to this connector to allow input and output of remote

control signals.

The IMX644 GPI port has eight inputs and eight outputs, plus a

dedicated “POWER MONITOR” output that indicates the unit’s

ON/OFF status.

The input pins are normally left open. Shorting an input pin to

ground (GND) recalls the corresponding memory number.

The output pins are open-collector outputs that deliver a maxi-

mum output of +35 volts, with a maximum current capability of

30 mA per port.

For the POWER MONITOR outputs, pins 24 and 25 are

“closed” (shorted) when the power is ON. The POWER MONI-

TOR COLD pin (pin 25) is internally connected to the GND

pins.

The IMX644 Manager application can be used for parameter as-

signment.

Mix Functions

The IMX644 mix functions can be programmed and edited in detail using the IMX644 Manager installed on a computer (page 7). The

mix functions that can be controlled by the IMX644 Manager application are discussed in this section. For operating details refer to the

IMX644 Manager Owner’s Manual.

To enable communication with the IMX644 Manager application, press and hold the IMX644 MEMORY [D] button while turning the

[POWER] switch ON.

■ GAIN

The gain of the mono input channel head amplifiers can be indi-

vidually adjusted and displayed.

■ INPUT EQ

The parameters of the input channel equalizers can be individu-

ally adjusted and displayed. The parameters available for each

channel are listed below.

MONO INPUT CHANNEL

STEREO INPUT CHANNEL

■ MATRIX

The MATRIX allows individual input channels to be assigned to

any of the mixer’s output channels. The assignments are shown

on the display. The initial default settings are: send assignments

to all output channels are ON, with only OUT1 assigned to the

REC OUT channel. The send levels from individual mono input

channels to the output channels can also be adjusted and dis-

played.

■ Temporary Matrix Assignment

Changes

The panel controls can be used to temporarily turn on the output

assignments of individual input channels, as follows.

1 Set all OUTPUT channel level controls to “0”.

2 Set the level of the INPUT channel to be

assigned to “10”.

3 Press and hold the MEMORY button correspond-

ing to the output channel you want to assign the

input channel to for longer than 3 seconds while

rotating the INPUT channel level control towards

“0”.

4 The corresponding MATRIX indicator will light.

5 Repeat for other channels as required.

NOTE

• Output assignments made in this way are only temporary and

will not be saved to memory. If power to the unit is turned

OFF and then ON again the memorized settings prior to

making the changes as described above will be recalled.

■ Feedback Suppressor

The Feedback Suppressor effectively controls feedback by iden-

tifying the feedback frequencies that will occur naturally as a re-

sult of the combined acoustic and electrical characteristics of the

sound system within the acoustic space in which it is used. The

Feedback Suppressor includes static filters that provide mea-

surement and filtering for specified channels, and dynamic fil-

ters that monitor the condition of specified MONO INPUT

channels and automatically suppress feedback as it occurs.

Static filter measurements can be made either via the IMX644

Manager application or the IMX644 unit itself. Measurement

from the IMX644 itself is described in “Front Panel Static Filter

Measurement” below.

With the initial default settings the static filters are inactive,

while the dynamic filters are ON for all MONO INPUT chan-

nels.

NOTE

• The initial default setting is Feedback Suppressor ON. Even

though the static ﬁlters are inactive, the dynamic ﬁlters are

still operational so be sure to turn the Feedback Suppressor

OFF before using sine waves or test tones to test or calibrate

the system.

•Feedback Suppressor settings can be stored in the unit’s 16

memories.

Front Panel Static Filter Measurement

To ensure optimum feedback suppression be sure to perform the

measurements under the same conditions that will prevail during

actual operation (microphone and speaker positions, etc.).

1 Set the OUTPUT channel 1 through 4 level con-

trols to 3 o’clock.

2 Set the level control of the MONO INPUT to

which the microphone that is to be used for

measurement is connected to 3 o’clock.

3 Set up the microphone at least 5 meters away

from the speakers.

4 Adjust the output level of the power ampliﬁer.

While speaking or singing into the microphone gradually

raise the output level of the power ampliﬁer to the level

that will be used in actual operation. Also clap your hands

near the microphone to make sure that feedback does not

occur.

5 Set the level control of the MONO INPUT channel

to which the microphone that is to be used for

measurement is connected to “0”.

6 Make sure the area being measured is silent.

7 Simultaneously press and hold MEMORY but-

tons [A], [C], and [D] for longer than two sec-

onds. The MEMORY [A], [C], and [D] button

indicators will light and static ﬁlter measure-

ment will begin. When the measurement process

has ﬁnished the static ﬁlter will be set according

to the results and the MEMORY button indica-

tors will return to their status prior to the mea-

surement.

NOTE

• If all four MEMORY button indicators light – [A], [B], [C], and

[D] – an error has occurred during measurement. To prevent

damage to the equipment the measurement will be aborted

and the erroneous data discarded. If this occurs try changing

the orientation of the microphone and speakers, lower the

ampliﬁer output, then repeat the procedure from step 1

above.

• Static ﬁlter measurement may not be successful if the overall

level is too high or the microphone is too close to one of the

speakers.

■ Priority Ducker

When a signal is applied to the specified MONO INPUT channel

the level of all STEREO INPUT signals assigned to the same

output are reduced to allow announcements made via the MONO

INPUT channel to stand out clearly from background music or

other program material, for example. When input to the specified

MONO INPUT channel ceases the level of the other “ducked”

channels returns to normal.

The initial default setting is OFF for all channels.

Both the amount of attenuation and the time it takes to return to

normal level can be programmed as required.

■ Music Override

When a signal is applied to the specified STEREO INPUT chan-

nel all other STEREO INPUT channels assigned to the same out-

put are automatically faded out and muted. When input to the

specified STEREO INPUT channel ceases the level of the other

muted channels fades in and returns to normal.

The initial default setting is OFF for all channels.

The time it takes to fade-in to normal level can be programmed

as required.

NOTE

• If Music Override is ON for more than one channel, the low-

est-numbered channel takes priority.

Parameter Range Initial value

Mute Level -30.2dB – 0dB -20dB

Release Time 0.0 – 6.0sec 2.0sec

Parameter Range Initial value

Release Time 0.0 – 6.0sec 4.0sec

Mix Functions

IMX644 Owner’s Manual 17

■ OUTPUT EQ

The parameters of the independent 6-band parametric equalizers

provided for OUTPUT channels 1 through 4 can be adjusted and

displayed. The following EQ types can be specified for each

band.

The initial default settings when the P.EQ type is selected are as

follows.

■ DELAY

Sets the output channel delay time.

One of the main uses for this feature is to delay the output to sub

speakers slightly compared to the main speakers, to create a solid

frontal sonic image.

■ BALANCE

Adjusts the A/B level balance for OUTPUT channels 1 and 2.

■ Output Format (STEREO/MONO)

Specifies whether OUTPUT channels 1 and 2 deliver a STEREO

or MONO output signal. When [STEREO] is selected the left

channel signal is delivered via the A connector and the right-

channel signal is delivered via the B connector. The initial de-

fault setting is [STEREO].

■ GPI (General Purpose Interface)

• GPI Input

Applying an appropriate input to one of the rear-panel GPI

input ports recalls the assigned memory. Individual assign-

ments can be made for each input port.

• GPI Output

Recalling a memory causes a pre-assigned combination of

ON and OFF outputs to appear at the GPI output ports. The

ON/OFF combinations can be independently assigned for

each memory.

The initial default assignments for all memories are all out-

puts OFF.

■ MEMORY

Up to 16 sets of parameters can be memorized. Of those, four

can be assigned for direct recall from the front-panel MEMORY

[A] through [D] buttons. For access to five or more memories at

a time either use the IMX644 Manager application, or a suitable

external controller connected to the GPI interface.

NOTE

• MEMORY buttons [A] through [D] are initially set up to recall

the same data.

• Since the level settings for each channel are stored in the

IMX644 unit itself, be sure that the IMX644 Manager

application is online when setting up the memories.
