milliseconds and 1 microsecond (depending on frequency). Model 4110 is similar in all respects, except thal it is configured for stereo operation. Model 4450A automatic level control automatically rides gain and features an expanded return-to-zero function. Recovery time is adjustable for optimum compatibility with program format. Its control characteristic is ± 10 dB of gain control; maximum gain is 40 dB.

CBS 4500 Dynamie Presence Equalizer

Model 4500 is designed to inerease amplitudę of the presence band (2 to 4 kHz) to overcome poor microphone technique, incorrect equalization, or excessive tape recording levels. Use of the speech-music discriminator module is optional and permits enhancing jusi speech, all programming, or removing control completely. The 4500 has a response of maximum boost to 10 dB at 3.4 kHz, or fiat (with no control) within 0.5 dB, 50 to 15,000 Hz. Input level is 0 to 23 dBm; maximum peak output level is 24 dBm; maximum gain is 19 dB.

CBS AM Limiting Amplifiers

For the AM broadcaster, CBS provides a complete linę of limiters, equalizers, level controlłers, and distribution amplifiers. The Model 4000 automatic peak controller provides control of speech asymmetry: it ensures that the highest amplitudę peaks always positively modulate the transmitter. Silent polarity switching occurs during the split-second pauses in a speech program with no obtrusive clicks. Negative peaks are controlled at 24 dBm; positive

CBS 1602 Distribution Amplifier

This dual-channel unit has two balanced bridging inputs rated at 15,000 ohms each. The 8 outputs are wired for 600 ohms, but each is fiefcł-convertible by changing two resistors. Input/output connection are on the rear panel; output jacks are located on the front panel for setup convenience. Both sections of the amplifier are delay-compensated to 3° at 15 kHz for stereo operation. Response is ± 0.5 dB, 20 Hz to 20 kHz; nominał gain is 20 dB, maximum gain is 40 dB.
