2Mode switch

STEREO mode

In STEREO mode, channels A and B are completely independent.

PARALLEL mode

In PARALLEL mode, the channel A input signal is sent both to the channel A power amp and the channel B amp. The Channel B input connector does not function.

BRIDGE mode

In BRIDGE mode, channels A and B operates simul- taneously, functioning as a single mono amplifier.

3GAIN switch

This switch is used when changing the Gain of the A and B channels simultaneously.

4DATA PORT jacks

An amp control unit, such as the ACU16-C, can be con- nected to the DATA PORT jack for monitoring or control- ling the amplifier from the external device.

5AMP ID switch

When an amp control unit, such as the ACU16-C, is con- nected to the DATA PORT jack 4, the AMP ID can be used to set the amplifier’s ID.

6SPEAKERS jacks

5-way binding post output jacks

Speakon type output jacks

Speakon type cable plugs (Neutrik NL4) can be con- nected here.

7Ground screw

If you are having a problem with hum or noise, use this ter- minal to connect to ground or connect to the chassis of the mixer, preamp, or other device in your system.

8AC IN connector

This amplifier uses a NEMA L5-30 outlet.

Connect the 30 A twist-lock connectors by orienting the locking L-shaped prong with the corresponding connector entry, then fully insert the three prongs. Twist the plug about 1/8 of a turn clockwise to lock the connector and plug.

The amplifier requires very high-power so that it can demand high current from the AC service. Connections must be properly rated for reliable operation.

If this device is to be rack mounted and transported frequently, be sure to support the rear end of the unit with mounting hardware that matches the size of the rack used.
