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. Please read this manual carefully.
A12 Stereo Integrated Amplifier 12 Power Switch 1A and Power Indicator 2 Phono Input - and Ground Connection (GND) 0 When the power switch is in the ON position, the remote control ON and OFF buttons may be used to activate the A12. In Standby mode the power LED is red, but the display is turned OFF. Line Level Inputs =qw Press the front panel Power Switch button 1 to turn the unit on. The Power Indicator light 2 is illuminated when the unit is on. Press Power Switch button again to turn the unit off.
Polarity and Phasing The polarity - the positive/negative orientation of the connections - for every speaker and amplifier connection must be consistent so all the speakers will be in phase. If the polarity of one connection is reversed, bass output will be very weak and stereo imaging degraded. All wire is marked so you can identify the two conductors. There may be ribs or a stripe on the insulation of one conductor.
A12 Stereo Integrated Amplifier 14 Bass and Treble Controls 9B Set the Bass or Treble controls from the front panel by pressing the MENU 9 button to the Bass and Treble Setting menu in sequence.
