CPS-121 Control Panel User Manual
5
The panel will be dark if the amplifier is in the OFF or STANDBY state. Turn the amplifier ON by long-
pressing the
- Mute
button (about 4 seconds). This will activate both the amplifier and the control
panel. If the screen is merely dim, then press any button momentarily to ready the panel to receive a
command; then it will return to full brightness, and you can press buttons to enter commands.
I cannot hear any audio from one of the inputs (mics or other inputs).
Press the button for that audio source (e.g. MicA or BT), then adjust the volume up to mid-range. If it had
been muted or turned down to minimum level, this will correct that. Alternatively, independently check
that the device sending audio (e.g. a microphone, computer, television) can successfully send audio to
another system (over the same cables) such as a powered speaker or another room’s TeachLogic
system.
Why does control panel blink the word “Standby?”
This simply means that the amplifier is in a standby mode (aka sleep mode). It can be changed into the
active mode by long pressing the power button on the panel or by using a microphone or audio source
connected to the amplifier.
