Input Connections

Microphone Connections

These inputs are for two low-impedance balanced dynamic microphones. Connect cable shield to center screw marked "GND."

Auxiliary

The AUX inputs provide unbalanced RCA inputs for connection to external signal-level equipment.

AUX Muting

For this function, a customer-supplied, normally-open contact closure (switch) must be connected to the AUX 2 MUTE terminals. When the contacts are closed, the AUX 2 input will be muted.Typically activated by a switch in a push-to-talk style microphone. AUX 1, if selected, is not mutable by contact closure.

TEL

AUX2 AUX1

Connect the telephone line to the two outside terminals and the shield, if used, to the center terminal. TEL input signal will trigger automatic muting of AUX 1 and AUX 2. Input impedance is 600-ohm and is trans- former balanced. Input is for "Dry" audio signals only, no DC voltage on the signal.

Output Connections

Speakers, General

The amplifier may be used with most conventional speaker sys- tems. Connect one speaker lead to the screw terminal that cor- responds to the impedance of the type of speakers used in the system and the other lead to the COM terminal. If the line is shielded, connect the shield to GND.

Connecting the GND to the COM terminal when using the trans- former-coupled outputs references the transformer output to ground. Disconnecting the GND terminal from COM allows the transformer output to float electrically. This is sometimes useful under certain conditions where a ground connection is undesir- able. It is generally a good idea to short the GND to the COM terminal regardless of output type (Trans or Direct).

Speakers, Low-Impedance

To connect a 4-ohm speaker, remove the the 4-ohm link and connect the speaker between 4-ohm and GND.

Tape/Booster Connection

To tape record the amplifier program, connect a patch cord from the TAPE/BOOSTER output jack to the input of a tape recorder. Can also be connected to the input of a booster amplifier.

WMT1A Connection

This output jack is directly connected to the 25V speaker tap and permits the connection of Bogen’s general-purpose matching transformer (WMT1A). The WMT1A steps the signal down by a 5:1 ratio, giving you a 600-ohm balanced signal that can drive long cable runs.
