DESCRIPTION

The Shure Model SE30* Gated Compressor/Mixer is a high-quality gated memory compressor combined with a self-contained, portable, three-input mixer and remote amplifier designed specifically for professional appli- cations in AM, FM, and TV broadcasting, film, tape, and disc recording, CATV, and sound reinforcement. An acces- sory cover is available (A100A) which covers the front controls and provides a handle, as well as a support stand for tilting the front panel upward for easier vision of con- trols during operation. An accessory rack-mount kit (A100B) is available for permanently installed program compressor applications.

Features include:

Three transformer coupled inputs, switchable, low im- pedance microphone or line level.

Individual feedback-type level controls for each input to provide maximum clipping and minimum noise levels over a wide dynamic range.

Low-frequency roll-off switch for each input.

Input 1 switchable on front panel to low-distortion, 1 kHz tone oscillator.

Mix bus jack for adding additional mixers for additional input capability.

Feedback-type output control (located after compres- sion attenuator) to provide optimum output noise level regardless of setting.

Binding posts for balanced 600-ohm line output plus professional three-pin male audio connector switchable from line to microphone level output.

Two-level headphone monitor jack for 600 to 2,000 ohm headphones.

Compression range of 40 dB, with a slope or compres- sion ratio of approximately 10 to 1 in the normal oper- ating range.

Gated Memory with a meter indicator to minimize “pumping.”

True average-responding compression to maximize output level regardless of peak-to-average ratio of pro- gram material, either music or speech. (Peak responding circuit to reduce gain rapidly for significant increases in the input signal.)

Response rate (averaging time constant) adjustment on front panel to compensate for various types of program material.

Extremely low distortion, noise, and RF susceptibility, with wide, flat frequency response at any level of com- pression.

+18 dB output capability.

Dual-scale illuminated meter for output VU indication or dB compression.

+4 or +6 dBm range switch for VU meter.

AC or battery operation with built-in battery supply using readily available 9-volt batteries.

(Model SE30 shown)

Automatic, noiseless switch-over to batteries in the event of ac line failure.

Battery-check switch to check battery condition with- out interrupting operation of unit.

Detachable ac line cord.

Auxiliary meter lamp operates independently from a “D” type dry cell for meter illumination when ac power is not available.

Auxiliary high level input and output on phone jacks for special applications (approximately --20 dBV). Microphone and line inputs and outputs phase indi- cated.

Stereo parallel jack for synchronizing the compression circuits of two units.

Listed by Underwriters’ Laboratories and Canadian Standards Association (SE30 only).
