PROCESSORS

SAMSON

S•COM / S•COM PLUS

740

Stereo Compressor / Limiters

The S•com is a dual-channel, single

rack space stereo compressor

designed to control signal levels

in a variety of applications. It’s

logical design and layout make

it simple to understand and

easy to use. Sonic integrity

offers clean, distortion free

audio, and a predictable, usable range of control from undetectable to clearly identifiable. Each channel combines an

Expander/Gate, a Compressor/Limiter and a fully adjustable Enhancer. This unique circuit reduces noise, increases

loudness and recovers high frequencies that might otherwise be compromised when audio is heavily compressed.

The Spectra switch adds a mid-band boost to the detector circuit to help smooth out harsh vocals.

The S•com PLUS has basically the same features, but also offers a variable de-esser to improve audio quality by removing

“S” from vocals and sibilance from overly bright sources such as cymbals. Both include a three-year extended warranty.

Expander/Gate

◆ The Expander/Gate features a variable

Threshold control and switchable

(fast/slow) Release time.

◆ Twin (open and closed) LEDs provide visual

confirmation of the gate's operation

Compressor / Limiter

◆ Compressor/Limiter controls include

variable threshold, ratio, attack, release and

output level.

◆ Switchable AEG (Auto Envelope Generator)

function continuously analyzes the audio

input, and automatically adjusts the attack

and release times based on the changing

level.

◆ EFR (Enhanced Frequency Recovery) circuit

helps restore high frequency content that

can be lost when high gain reduction is

applied.

◆

The SKD (Smart Knee Detector) automatically

chooses between hard or soft knee

compression curve—based on the program

material. A hard knee curve activates the

compression circuit only when the audio

signal exceeds the threshold vs. a soft knee

curve which gradually increases the

compression ratio until the threshold is met.

Metering

◆ 12-segment LED meter is provided for Gain

Reduction levels.

◆ Another 12-segment LED meter can be

switched to display input or output levels.

Inputs and Outputs

◆ Servo balanced inputs and outputs on XLR

and 1/4” connectors with switchable +4 and

-10 operating levels.

◆ 1/4” key inputs and outputs

Additional Features

◆ A Key input switch, allows you to use an

external audio source to control processing.

For example, the signal from a kick drum

trigger the amount of compression applied

to a bass or you can use an EQ to specify

which frequencies should be used to

control dynamics.

◆ A link switch allows true stereo operation

with channel one controlling the processing

of both channels.

S•COM Only

◆ A Key Listen feature allows you to

audition the Key input signal.

◆ An Enhancer level control allows you

to adjust the amount of Enhanced

Frequency Recovery being applied to

the signal

◆ In lieu of a dedicated de-esser, a

switchable Spectra circuit allows you to

add a mid-band boost to the detector

circuit to tame sibilant vocals

S•COMPLUSOnly

◆ A switchable de-esser circuit with

variable level control, helps you tame

harsh and sibilant vocals. A five

segment LED meter shows you the

amount of high frequency gain

reduction being applied to the signal

◆ A dedicated Peak Limiter ensures that

output levels do not exceed the desired

threshold level. Ideal for speaker protec-

tion in your PA rig and for recording

and mixdown, especially to digital

devices. An LED lets you know when

the threshold level has been exceeded

and the Limiter circuit is activated.
