Sonifex RB-DS2
The Sonifex RB-DS2 is a stereo audio delay synchroniser used for resynchronising audio to video following delay processes such as standards conversion, transmission.
Original price was: €1,865.00.€1,775.00Current price is: €1,775.00.
The Sonifex RB-DS2 is a high-quality stereo audio delay synchroniser, designed to resynchronise audio to video after various delay-inducing processes such as standards conversion, transmission delay, logo insertion, video aspect ratio conversion, and network delays. It supports digital audio signals up to 96kHz, 24 bit, ensuring superb sonic quality and smooth, silent switching for clean audio delay.
Key Features:
- Inputs & Outputs:
- Balanced analogue and AES/EBU digital audio on 3-pin XLR connectors.
- Can function as an A/D and D/A unit, allowing analogue inputs to be delayed and output as AES/EBU or vice-versa.
- Can be used in stereo, dual mono, or mono modes.
- Delay Capabilities:
- Standard delay: Up to 10.5 seconds at 96kHz, 24 bit (42 seconds at 48kHz, 16 bit).
- Expanded delay: With Compact Flash™ expansion (up to 2GB), delay times exceed 4 hours.
- Delay time units: Samples, fields, frames, meters, milliseconds, and hh:mm
(with CF expansion).
- User Interface:
- Blue vacuum fluorescent display with rotary controller.
- Settings include source selection (analogue/digital), channels, sample rate, bit width, format (PAL/NTSC), delay units, and delay time.
- Input peak levels: Selectable from +12dBu, +18dBu, and +24dBu for FSD.
- Rear panel pre-set potentiometers adjust input gain by ±3dB around the selected peak digits.
- Output Control:
- Analogue output gain: Adjustable in software from -6dBu to +24dBu output level, ref FSD.
- Separate muting for both analogue and digital outputs.
- Bypass function: Diverts both analogue and digital inputs to their outputs via electro-mechanical relays, also engaged automatically during power-fail.
- Remote and Security Features:
- Eight configurable settings can be saved and loaded, remotely controlled using GPI contacts.
- RS232 serial port for remote control.
- Front panel controls can be locked-out for remote operations or physical security.
