Sonifex S2-CDAS Dual Stereo Line Channel

The S2-CDAS dual stereo line channel has one 24-bit 96kHz AES/EBU digital input and one balanced analogue stereo input, both on Neutrik XLR connectors.

The INP 1/INP 2 button selects which input is routed through the channel. The button is illuminated in red to indicate when Input 2 the balanced analogue source is selected. The operation of the button is inhibited when the channel is "live".

Input 1 is configured to be the AES/EBU input on standard XLR. An additional jumper option can be used to decode emphasis when indicated by certain status bits in the incoming data stream.

The digital signals are converted to analogue and from this point the channel functions are the same as the S2-CS Dual Stereo Line channel with the addition that when Input 1 is selected and the ON button flashes green, it means that there is no valid digital input signal being received.

There are separate logic remote output controls for both of the two inputs providing start/stop functions by fader, or ON button. Remotes, etc, are triggered when the fader is up and the channel ON button shows green. The start function can be configured to be either momentary (500mS) or latched for each input. The remote outputs on the 9 way D-type plug are fed from NPN opto-isolators.

Continuous momentary start can be enabled such that when the fader is up and the channel is on, each press of the ON button triggers a momentary start.

Two remote pins can also be configured for general use as either inputs, outputs, latching, or momentary and active high or low. Uses for this include channel live indication or specific channel function remote control.

The BAL/PAN control adjusts the stereo balance in the following manner : Full anti-clockwise shifts the signal to the left and increases the signal by 6dB (right channel reduces by 6dB); full clockwise shifts the signal to the right and increases the signal by 6dB (left channel reduces by 6dB).

The 100mm VCA fader provides unity gain when fully open. The channel input signal is routed to the outputs whenever the fader is open, the ON button is selected and either or both of the routing buttons are selected.

The channel can be used to control either one of two separate timer displays.

S2-PSU Power Supply
The new 1U sized S2-PSU is pin compatible with the original 2U sized S2-PSU power supply, so can be used as a straight like-for-like swap, using the same connection cables. The new units have a serial number greater than 16852 and have a great deal of improvements on the original design

S2-PSUS Power Supply Switcher
The S2-PSUS is a passive power switcher which takes the power feeds from 2 x S2-PSU units and switches between them in the event of failure. Two trailing leads 0.5m in length connect to 2 x S2-PSU units. With LED failure indicators and GPI alarms, the S2-PSUS is the perfect dual redundant power supply module.
