Powering ON or OFF
•To prevent loud noise bursts from the speakers when powering up the system, turn devices on in the following order:
audio sources, SB168-ES, digital mixer, and finally power amplifiers. Reverse this order when turning the system off.
1. Press the [POWER] switch to turn the unit ON.
2. Press the [POWER] switch a second time to turn the unit OFF.
• The unit consumes a very small “standby” voltage even when the power switch is turned OFF. Be sure to unplug the AC
power cable if the unit will not be used for an extended period of time.
• Rapidly turning the unit ON and OFF in succession can cause it to malfunction. After turning the unit OFF, wait for about
6 seconds before turning it ON again.
Precautions for Rack Mounting
This unit is rated for operation at ambient temperatures ranging from 0 to 40 degrees Celsius. When mounting the unit with
other SB168-ES unit(s) or other device(s) in an EIA standard equipment rack, internal temperatures can exceed the specified
upper limit, resulting in impaired performance or failure.
Always observe the following when rack mounting the unit:
• If three or more SB168-ES units are mounted without space in the same rack, set the fan speeds to HIGH.
• If multiple SB168-ES units are mounted in the same rack with their fan speeds set to LOW, leave a 1U rack space between
every two units. Also either leave the open spaces uncovered or install appropriate ventilating panels to minimize the possi-
bility of heat buildup.
• When mounting the unit in a rack with devices such as power amplifiers that generate a significant amount of heat, leave
more than 1U of space between the SB168-ES and other device. Also either leave the open spaces uncovered or install appro-
priate ventilating panels to minimize the possibility of heat buildup.
•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.
Recessed installation
If you want to recess the front panel surface of the device from the front edge of the rack, you can adjust the position of the rack
mount brackets to recess the device by 50mm or 100mm.
• When you install the brackets, use the same screws that you just removed.
Resetting the Unit to Initial Factory Condition (Initialization)
This operation initializes the internal backup memory, resetting all head amplifier parameters to the original factory settings.
1. Turn the power OFF.
2. Move front-panel DIP switches 6 and 8 down to
the ON position, then turn the power ON.
Initialization will take about one second.
When initialization is complete all [PEAK] indicators
on the front panel will flash. At the same time the OUT
[TX]/IN [RX] indicators will flash and the IN [TX]
indicator will light.
3. Turn the power OFF, return DIP switches 6 and
8 to their original positions, then turn the power
ON again.
