I. Source-Output, Power Connections and Controls
The connectors and controls are clearly marked on the back panel of the AMPLIFIER
Note the correct left or right channel orientation. The function and channel markings on
the rear panel correspond to the front panel controls and their signal paths.
1.The UNBALANCE 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.
2.The LEFT OUTPUT, RIGHT OUTPUT should be attached to the left and right speakers.
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.
3. The MAIN POWER switch, once all appropriate connectsions are made, may be left on
as the
AMPLIFIER draws a negligible amount of current when the BIAS is turned off.
4.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.
5.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
S5 SS
is properly connected, the
S
appropriate AC power source. Once the AMPLIFIER
power switch may be turned on and the led on the front panel will light indicating a ready
state.
