SLN-4

The SLN-4 is a four channel outboard noise gate for the
SymbiLink

 Balanced Signal System.  Car audio systems

sometimes use poor quality signal processors, such as third

octave equalizers, that generate noticeable amounts of noise.

The SLN-4 can mute or low-pass the audio signal when the signal

level drops below a specified level.  The SLN-4 can mute up to

four channels in tandem.

The SLN-4 features an onboard power supply, allowing it to

operate in a stand-alone application or powered by other

SymbiLink products, through the balanced cables.  An optional

trigger line is available from the DAII-SL D/A converter that mutes

the audio when it detects a succession of zero bit audio data.

The SLN-4 introduces virtually no noise or distortion into the

system.  SNR measures an astonishing 146dB muted and 138dB

un-muted with less than .0005% THD+N!
