GENERAL DESCRIPTION

The Samson S•Com plus is a one rack space, dual
channel dynamics processor optimized for recording,
live sound reinforcement systems, DJ set-ups and
commercial installations. The S•Com plus is a complete
dynamics processing solution offering two channels
of full function Compressor, Expander/Gate, Limiter
and De-Esser. S•Com plus’ convenient meters provide
instant status of important gain management settings.

FEATURES

> Full featured, dual channel dynamics processor

including Compressor/Limiter, Expander/Gate, De­Esser and Peak Limiter.

> SKD (Smart Knee Detector) switches from soft to

hard knee based on the level of input signal.

> AEG (Automatic Envelope Generator) mode constantly

adjusts the Compressor’s Attack and Release times
based on input signal. Manual adjustment of Attack
and Release time is also facilitated.

> 12 Segment LED Input/Output Meter, plus 12

Segment LED Gain Reduction Meter.

> External Keying with Key Switch available on front panel.

> Adjustable De-Esser with independent LED meter for

reducing sibilance from recorded tracks.

> Expander/Gate with variable Trigger control and

switchable Fast and Slow Release time.

CATEGO RY

> Gate function can be switched from hard off to light

Downward Expander.

> Gate Open and Closed LED's.

> Peak Limiter with independent threshold control and Limit LED.

> Advanced circuit design, utilizing low noise operational

amplifiers and high quality VCAs.

> Stereo Link Switch.

> Servo balanced inputs and outputs on XLR and 1/4” connectors.

> Switchable +4 and –10 operating levels.

> High quality, 41 position detent pots and backlit switches.

> Three-year extended warranty.

ARCHITECT’S & ENGINEER’S SPECIFICATIONS

The S•Com plus shall be a 2 channel compressor/limiter. It
shall have XLR and 1/4 inch inputs and outputs with a +4 /

-10 operation output level switch. Each channel shall have
a 1/4 inch key input and 1/4 inch key output. A Key enable
switch will also be available on the front panel. Each channel
shall have an expander/gate with a switchable Release time,
variable Trigger control, and gate open/close indicator.
The compressor controls shall be Threshold, Ratio, Attack,
Release, and Output level. An Auto switch will be available
for automatic automatic attack and release time settings on
the

compressor. An independant limiter circuit and variable
