Mounting

The 596LB is provided with a rear-case hang-up button for use with a mounting bracket on or near associated equipment. The bracket has mounting holes with clearance for No. 6 or No. 8 screws (not supplied).

Connections

The internal switch connections of the 596LB are shown in Figure 1. The 596LB has a four-conductor, coiled-cord cable (two conductors shielded) and a double-pole, double-throw, push-button switch to control the microphone circuit and an external relay or switching circuit. The RED and BLACK unshielded leads control the relay or switching circuit. Refer to the following tables and to the wiring diagram below.

The 596LB can be wired for balanced-line operation and is recommended for use where long cable lengths are required, or conditions where severe hum pickup may exist. The 596LB can be fed directly into a standard low-impedance amplifier input, or a Shure A95 Series Line Matching Transformer (at the equipment end of the cable) can be used for coupling the 596LB to the input of a high-impedance amplifier. A two-conductor shielded cable can be used for extending only the microphone circuit. If both the microphone and the remote circuit are to be extended, a four-conductor with two shielded conductors should be used.

The microphone circuit of the 596LB is normally open when the microphone switch button is not depressed.

Operation

The 596LB will operate satisfactorily under most conditions of humidity, heat and cold. Dropping the microphone or other severe mechanical shocks should be avoided.
