A12MKII Stereo Integrated Amplifier 10 A Few Precautions WARNING: To avoid potential damage to your system, turn off ALL the components in the system when connecting or disconnecting the loudspeakers or any associated components. Do not turn the system components back on until you are sure all the connections are correct and secure. Pay particular attention to the speaker wires. There must be no loose strands that could contact the other speaker wires, or the chassis of the amplifier.
Protection Indicator 2 Preamp Output p The amplifier has both thermal and over-current protection circuitry that protects the amplifier against damage in the event of extreme or faulty operating conditions. The protection circuits are independent of the audio signal and have no impact on sonic performance. Instead, the protection circuits monitor the temperature of the output devices and shut down the amplifier if temperatures exceed safe limits.
A12MKII Stereo Integrated Amplifier 12 If you are using terminal lugs, connect them to the wires. If you are attaching bare wires directly to the binding posts, separate the wire conductors and strip the insulation from the end of each conductor. Be careful not to cut into the wire strands. Unscrew (turn counterclockwise) the binding post thumbscrews. Place the connector lug or wire around the binding post shaft. Turn the thumbscrews clockwise to clamp the connector lug or wire firmly in place.

NOTE: This setting is stored permanently even after the A12MKII is powered off. •B ALANCE: Change left/right balance. (For more information refer to Balance Control section.) NOTE: This settings is stored permanently even after the A12MKII is powered off. A12MKII Stereo Integrated Amplifier • F IXED GAIN: Configures a Fixed Volume level for a specified input.
Troubleshooting Most difficulties in audio systems are the result of incorrect connections, or improper control settings. If you encounter problems, isolate the area of the difficulty, check the control settings, determine the cause of the fault and make the necessary changes.

Rotel A12 / A12MKII / A14 /A14MKII RS232 / IP ASCII Controller Command List Date August 25, 2016 Version 1.00 Update Description Original Specification The A12, A12MKII , A14 and A14MKII support an ASCII based RS232 protocol. The RS232 hardware does not support flow control so care needs to be take when sending and receiving data to avoid packet loss. A14 will also support IP control using the same command formats. All commands sent to the attached Rotel device must have a terminating “!” character.
