The first section of the installation instructions for the AMPLIFIER v12 is a diagram of the
default four channel configuration required to bring this amplifier into an operating
mode. These brief steps will allow you to begin operating your system. Make sure during
installation that the main AC power switch on the back of the AMPLIFIER v12 is turned off.
While the diagram may be self explanatory, we strongly recommend that you read the
detailed instructions following this introductory section.

I. Source-Output, Power Connections and Controls
The connectors and controls are clearly marked on the back panel of the AMPLIFIER v10.
Note the correct channel orientation. The function and channel markings on the rear
panel correspond to the front panel controls and their signal paths.
1. The MODE switch selects between unbridged or bridged operation. The default
position is UNBRIDGED. For information on bridging see BRIDGE SETUP.
2. The UNBALANCED and BALANCED inputs should be attached to the appropriate
unbalanced and balanced outputs of a preamplifier either directly or through a
crossover or processor, as appropriate to the application.
3. The CH1 OUTPUT, CH 2 OUTPUT, CH 3 OUTPUT, CH 4 OUTPUT should be attached to four
or three or two speakers. This will depend on how many channels are bridged.
NOTE: THERE ARE NO OUTPUT FUSES SO AS TO INSURE A LOW OUTPUT IMPEDANCE.
SPEAKER PROTECTION IS LEFT TO THE SPEAKER MANUFACTER AS THEY WOULD BEST
KNOW HOW TO PROTECT THEIR SPEAKER.
4. The MAIN POWER switch, once all appropriate connectsions are made, may be left on
as the AMPLIFIER v10 draws a negligible amount of current when the BIAS is turned off.
5. The FUSE AND VOLTAGE SELECTOR houses a 5 X 20 slow blow fuse and voltage selector
cartridge. Should the fuse blow, contact a Coda dealer or call Coda directly. When
changing the fuse, or altering the voltage selection be sure this unit is disconected from
its AC power source.
6. The AC LINE INPUT should be attached to the power cable provided with the amplifier.
After making the appropriate connections insert the three prong safety plug into an
appropriate AC power source. Once the AMPLIFIER v10 is properly connected, the
power switch may be turned on and the led on the front panel will light indicating a ready
state.

II. Front Panel Control Functions and Indicators
1. The BIAS button turns on the bias and opens shunting relays that mute the input.
2. The INPUT SELECTOR button switches between the balanced and unbalanced inputs.
3. These LEDs when lit, indicate that the bias is activated in the AMPLIFIER v12.
4. This two color LED indicates that the main power is on. When it is green the balanced
inputs are in use. When it is yellow the unbalanced inputs are in use.

Note: If a power interruption occurs to the system the AMPLIFIER v12 defaults to bias off.
