Low-Impedance Speaker Connections

When the amplifier is set to either the stereo mode or the Dual Mono mode (see Operation section), low-impedance speakers can be connected to either the "A" or "B" speaker output terminals. The

amplifier is designed to work into speaker load impedances as low as 3.2 ohms.

The speaker terminals can accept up to a #10 spade lug and have inte-

gral clamping plates which make wiring easier.The polarity of each set of speaker outputs (A & B) is indicated with a "+" and "-" sign. Use these indicators to ensure that the phasing of the speakers are correct. Do not ground the "+" output of either set of outputs. Doing so will cause the amplifier to go into protect mode, shut- ting down operation of the affected channel.

Note: The "+" and "-" indicators are mirrored on "A" and "B" outputs. Be sure to make the correct connections.

Earth Ground Terminal

The earth ground terminal is provided as a convenient means to con- nect to the amplifier’s chassis/AC ground, if necessary. DO NOT con- nect the earth ground terminal to the "+" terminals of either output. No damage will occur if this is done, but the amplifier will go into pro- tect mode and shut down the effected channel.

70V "Transformer-Coupled" Speakers

The 70V speaker output terminals are only usable when the amplifier

is in the 70V Mono mode (see Operation section). In this mode, both channels are bridged into a single mono channel. Use only speakers

that are designed to work with 70V audio systems when connecting to these terminals.The speaker terminals can accept up to a #10 ring

lug and have integral clamping plates which make wiring easier. The 70V output terminals are indicated by a yellow field above them.The polarity of the output terminals is indicated for speaker phasing pur-

poses. These output terminals must float and cannot be referenced to earth ground, so if they become ground- ed, the amplifier will go into protect mode, shutting down operation of the amplifier even though no damage to the amplifier will occur.

BAL1S Module Input

Balanced Input Connections

Balanced input connections are used when the source device pro- vides a balanced output (signal "+", signal "-", and ground "G").This type of connection is desirable when operating in electrically noisy environments, where long input cable runs are needed, or to ensure the lowest noise operation. If compatible with the source device, this type of connection is recommended.

Unbalanced Input Connections

When the source device provides only an unbalanced output

(signal and ground), the BAL1S input should be wired with "-" input shorted to ground (G). The unbalanced signal's shield wire is connected to BAL1S ground and the signal hot wire is connected to the "+" terminal. Since unbalanced connections do not provide the same amount of noise immunity that a bal-

anced connection does, the connection distances should be made as short as possible.
