CBS 710 Automatic Loudness Controller

The Model 710 is designed to reduce those portions of the audio signal which may sound excessively loud. The loudness analyzer portion of the Circuit compares the signal to an ear sensitivity characteristic. If the signal does not exceed the pre determined threshold, the system operates as a unity gain amplifier. If the threshold is exceeded, the analyzer suppresses the offending portion of the spectrum until the passage is over. Attack time is 100 milliseconds; recovery time is 2.5 seconds. Maximum peak output level is + 25 dBm; gain is 0 to -6 dB, automatically variable. For stereo operation, Model 711 is used, consisting of two Model 710 units strapped and mounted together.

CBS/Sony SQE-2000 Quad Encoder/Mixer

The CBS/Sony Encoder/Mixer provides the broadcaster or producer with fuli quadraphonic production capability. While not required to broadcast 4-channel records, the unit does provide capability to broadcast 4-channel tapes, and permits local production of 4-channel programs. The SQE-2000 produces signals completely compatible with all stereo and mono receivers and matched to practically every type of decoder offered for home receivers. The unit features accurate phase characteristic and frequency response; basie SQ encoding plus interior-, forward-, and back-oriented encoding for special quadraphonic effect; four linę inputs for broadcasting 4-channel tapes; four low-impedance mikę jacks; stereo mixing through double 4-channel linear potentiometers; stereo headphone monitoring; and optional 12 volt power supply for remote pickup applications.

SIZE: 6-1/8” (15.5 cm)H; 15-3/4” (40 cm)W; 12-5/8” (32 cm)D.

WEIGHT: 16.6 Ibs (7.5 kg).

Crown Stereo Audio Amplifiers

The Crown series of stereo amplifiers are ideał where exceptionally high fidelity is required. The all solid State Systems are designed and engineered to handle all types of loads, including electrostatic speaker systems. They also may be used as add-on units for quadraphonic installations. Model D-60, a 60-watt unit has power response of ± 1 dB 5 Hz to 30 kHz at 30 watts, both channels. Frequency response is ± 0.1 dB, 20 Hz to 20 kHz; total harmonie distortion is less than 0.05% at 30 watts. The D-150 model is rated at 75 watts per channel. Its characteristics are similar to the D-60. For larger applications, the DC-300A model is availab!e with a rating of 150 watts per channel. It has similar characteristics to the D-60 model. An optional rack-mounting kit is available as are oiled walnut enclosures.

SIZE: (D-60) 1-3/4" (4.4 cm)H; 17” (43.2 cm)W; 8-3/4" (22.1 cm)D.
