Sonifex Redbox RB SD1 Silence Detector dual analogue in out change ( x2 ). Condition is Used. Dispatched with Royal Mail 2nd Class.
2x working Sonifex Redbox SD1, Image of actual item.
TWO Stereo (or quad mono) Analogue inputs and stereo (twin mono) analogue outputs
This has been tested in mono and stereo modes
This is a USED item and has minor marks on it
The following is information from the official Sonifex website
Sonifex RB SD1 has two stereo inputs, designated A and B, which are assigned as the Main or Aux signal using a switch on the front-panel. The front panel has four LEDs indicate programme presence
and alarm conditions for each channel of the two sources. When the signal on any input remains below the threshold level for a preset period of time, the associated front panel alarm LED illuminates
and if the audio routing feature is enabled, the output is switched to the Aux signal. Three further indicators are used to show the status of the Source, Mode and Restore functions, adjacent to push
switches for setting these functions.
For mono sources, the alarm can be set to trigger on the loss of signal level on either input channel, and for stereo sources the alarm triggers when both left and right inputs fail. In manual restore mode,
the alarm must be reset from the front panel or remotely. If the automatic restore mode is chosen, the main source will be routed to the output two seconds after the programme returns.
The unit is equipped for remote operation; the alarm outputs from both Main and Aux detectors and the front-panel switch functions available. A start signal is also available to activate an external device,
such as a tape or CD player, when the alarm triggers. The audio inputs and outputs are designed for balanced line level connections. However, in consumer mode, Input B accepts unbalanced equipment and applies 12 dB of make-up gain.
The rear panel has two pairs of female 3-pin XLR connectors for inputs A and B, and one pair of 3-pin XLR outputs. In the un-powered state, input connectors A are routed to the output. There are two 16-position
rotary switches; silence detect level is adjustable between -60dBu and -15dBu in 3dBu steps and silence interval can also be adjusted between 2 and 30 seconds in 2 second steps. An additional maximum delay setting
of 125 seconds is available, which can also activated remotely to minimise false alarms on quiet programme passages. A 15-pin male D-sub connector provides connections for the remote controls.
Input: +28dBu maximum, 0dBu nominal, greater than100k ohm, balanced. Gain: 0dB, +8dB for input B in consumer mode. Response: 20Hz to 20kHz +/-0.1dB. Distortion: 0.05% THD, 1kHz, +8dBu output. Noise: -87dB,
unity gain, +8dBu output. Output impedance: As input source, or less than 50ohms for Input B in consumer mode. Power source: 110-120V or 220-240V AC 6W maximum
