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.
Features
■ 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 inputs, 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 instantly 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 example) 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: 3band 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 feedback.
• Priority for Specified Voice or Music Sources
The Priority Ducker automatically “ducks” (reduces the volume of) the background when a signal is applied to a specified 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 priority 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
Precautions for Rack
Mounting
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 temperature inside the rack, resulting in inefficient performance. To ensure that the heat produced by this device can be dissipated appropriately, please ensure the following conditions when rackmounting 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-producing equipment such as power amplifiers, leave 1U or more space between it and other devices. Install a ventilation panel in this vacant space or leave it open to ensure adequate 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 produce a greater cooling effect. Refer to the rack and/or fan unit manual for details.
Before Operation
■ 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 appropriate 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 powering 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.
1
Press the [ON] end of the [POWER] switch to turn the unit ON.
2
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 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 maximum 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 assignment.

Mix Functions
■ Feedback Suppressor
The Feedback Suppressor effectively controls feedback by identifying the feedback frequencies that will occur naturally as a result 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 measurement and filtering for specified channels, and dynamic filters 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 channels.
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 controls 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 buttons [A], [C], and [D] for longer than two seconds. The MEMORY [A], [C], and [D] button indicators will light and static filter measurement will begin. When the measurement process has finished the static filter will be set according to the results and the MEMORY button indicators will return to their status prior to the measurement.
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 channel all other STEREO INPUT channels assigned to the same output 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 lowest-numbered channel takes priority.

Others
■ GPI (General Purpose Interface)
• GPI Input
Applying an appropriate input to one of the rear-panel GPI input ports recalls the assigned memory. Individual assignments 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 outputs 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.
