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.
