CA18 Power Amplifier - Special Functions

The CA18 rear panel features external switches for the following:

XLR Pin+ Switch: This switch configures XLR input connection polarity. Either pin 2 or pin 3 may be selected as the “hot” (+) pin. Amplifiers are shipped pin 2 “hot” (+) from the factory.

Gain Switch: This switch permits the amplifier to be configured for the standard input sensitivity (.775V for rated power @ 8Ω ), or for optional voltage gains of X40 or X20. Refer to the specifications for input sensitivity values at optional voltage gains of X40 and X20.

NOTE: on the 5-way Output Binding Post version of the CA18, two pairs of 5-way binding posts are provid- ed for each channel, so that paralleling of speakers is possible.

ALWAYS power down the amplifier before changing settings with either the XLR Pin+ switch or the Gain switch!
