[. . . ] 3 Make sure to set the following conditions: your Preamplifier's volume level set to minimum and C 245BEE's +12V Trigger IN switch set to "OFF" position. 4 Connect the AC cord to the C 245BEE's AC Mains input and then plug into an AC outlet. 5 Switch the POWER switch on the rear panel to the "ON" setting in order to turn the C 245BEE to standby mode. The Standby LED indicator embedded around the bezel of the STANDBY button will illuminate amber. 7 Press the front panel button CHANNEL A (or CHANNEL B) to select desired input source. BARE WIRES AND PIN CONNECTORS warning: The terminals marked with this symbol are hazardous live. Do not use solutions containing benzol or other volatile agents.

Pressing the STANDBY button again turns the unit back to standby mode. IMPORTANTNOTICE TherearpanelPOWERswitchmustbeintheONpositionforthe STANDBYbuttontoactivate. 2 StandbY led: This indicator will light up amber when the C 245BEE is in standby state. When the C 245BEE is at ON state, this indicator will illuminate blue. In cases of serious abuse of the C 245BEE, such as excessively low loudspeaker impedance and short circuit, the C 245BEE will engage its Protection circuitry, indicated by the Standby LED turning from blue to red and the sound being muted. In such a case, turn the C 245BEE OFF by the rear panel POWER switch, wait for it to cool down and/or check the speaker connections, making sure the overall loudspeaker impedance doesn't go below 4 ohms or 8 ohms in Bridge mode. Once the cause for the protection circuitry to engage has been removed, switch ON the rear POWER switch and the Standby button to resume normal operation. 3 channel a: Press to select the input source connected at the rear panel CHANNEL A input sockets. 4 channel b: Press to select the input source connected at the rear panel CHANNEL B input sockets. Both CHANNEL A and CHANNEL B can be activated at the same time if an input source is connected to their respective rear panel channel input sockets.

Connect the terminals marked "L+" and "L-" to the left speaker in the same way. In Bridge Mode, connect the single speaker to the terminals marked "R +" and "L+" ensuring that the "L+" is connected to the "+" terminal on your loudspeaker and the "R+" is connected to the loudspeaker's "-" terminal. 2 bridge mode (applicable to channel b only): Set the BRIDGE MODE switch to the "ON" position and connect the speaker to the terminals marked "L +" and "R+" ensuring that the "L+" is connected to the "+" terminal of your loudspeaker and the "R+" is connected to the loudspeaker's " - " terminal. 3 channel b (in/out): Connect the output from a pre-amplifier or processor, such as a surround-sound decoder, to this set of CHANNEL B IN sockets. Use a twin RCA-to-RCA lead to connect the left and right "Audio Output" of the preamplifier or processor to these CHANNEL B input sockets. The same level of input signal at the CHANNEL B IN sockets is available at CHANNEL B OUT sockets thereby allowing the same signal to be shared or passed on to another amplifier. [. . . ] The ON/OFF power control is managed by the Automated Turn-On logic or ATO Logic circuit that requires the C 245BEE to be switched back to standby mode in the same manner by which it was activated. In other words, if the C 245BEE is switched ON via a +12V-control signal, it cannot be switched to standby mode via the front panel STANDBY button, it must wait for removal of the +12V-control signal. In practice, you probably would use only one of the methods once your C 245BEE is installed.
