Troubleshooting
If you experience any problems with the unit, please take a moment
to look through this chart and see if you can solve the problem
yourself before you call your dealer or ESOTERIC customer service/
technical support.
Moreover, the problem might be caused by something other than this
unit. Confirm that connected devices are also being used properly.
No power.
e Check the connection to the AC power source. Check and
make sure the AC source is not a switched outlet and if it is, the
switch is turned on. Make sure there is power to the AC outlet by
plugging another item such as a lamp or a fan.
Remote control does not work.
e Press the POWER button of the main unit to turn it on.
e Be sure that batteries have been installed. If the batteries are
exhausted, change the batteries (Page 7).
e Use the remote control unit within the effective range
(23 feet/7 m) and point it toward the remote sensor on the front
panel.
e Make sure that there are no obstacles between the remote
control unit and the main unit.
e If a fluorescent light is near the unit, turn it off.
Other units with remote controls operate incorrectly.
e Note that other units with remote controls may operate
incorrectly because of infrared light “overspill” when you operate
the remote control of this unit.
There is no sound or only a very low-level sound is heard.
e Adjust the volume by turning the VOLUME knob.
e Select the proper input source by turning the INPUT knob.
e If the muting is engaged, press the MUTING button.
e Check that the speakers and components are connected
properly.
e Check the operation of the connected component.
e The connected speakers will make no sound when headphones
are plugged into this unit. Disconnect the headphones.
e When you use this unit as a pre amplifier, set the Pre out setting
to “ON1” or “ON2” (page 16).
e The connected speakers will make no sound when the Pre out
setting is set to “ON2” (page 16).
e The connected speakers will make no sound when the protection
circuit is activated. Check the items on the right.
“AMP ERR!” blinks on the display.
e The protection circuit is activated. Check the items on the right.
Cannot select the input terminal.
e The input terminal might be set to be skipped. Assign the input
terminal a name other than “*skip” (page 17).
VOLUME knob/buttons do not work.
e When you set the RCA2 terminals to “THRU” (signal through
terminals), the VOLUME knob/buttons do not work on their
terminals (page 16).
e When you set the PRE OUT terminals to “REC”, the VOLUME knob/
buttons do not work on their terminals (page 16).
Volume display blinks.
e The volume value exceeds the maximum total gain value of
the volume control. Lower the volume until the display stops
blinking.
Since this device uses a microcontroller, external noise and
other interference can cause the unit to malfunction. If this
occurs, turn the power off and restart operations after waiting
for about one minute.
Protection Circuit
This unit has a built-in protection circuit.
“AMP ERR!” blinks on the display when the protection circuit is
activated. In this case, check the following items:
Check the speaker cables
e There might be a ¥/^ short in a speaker cable. Turn the
unit off, and then check the cables.
Check if the volume is too high
e Lower the volume.
Check if the unit is too warm
e The protection circuit might be activated because the
temperature inside the unit has become too hot.
Turn the unit off, and wait to let it cool down.
Always be sure to allow adequate space for airflow around
the unit when in operation.
If the protection circuit continues to be activated, please
contact your dealer or an ESOTERIC authorized service center.
