Description
Rack Mount or Table top (Shelf version with wood side panels) are available.
This 3U VU unit is suitable to any Studer Reel to Reel machine – or any other recorder – which comes without VU meters to enable control and monitor of recording and playback levels. Ensures calibrated and un-calibrated level control modes of recording and playback. VU meters can be switched between normal and “peak” modes with a simple push of a switch. In “peak mode” ballistics of VU meters are adjusted to show peak values of recording/playback.
The VU meter indicator circuitry is a modified replica of the Studer A810 (also A812, A816) including a switchable standard VU meter mode and a peak program meter (PPM) mode. In addition, there is a switch to increase the sensitivity by 10dB. -10 VU mode is also useful when calibrating the recorder with a test tape where tones are recorded at a level of -10 dB below nominal and you do not have external audio frequency VU meter.
Our Mark 5 version has built in oscillator – generator of 1khHz and 10kHz sinus test tones for testing and calibration. Linear power supply available as option.
Unit’s “0” value for VU meters is calibrated to “normal” Studer (studio standard) level – +4dB. “0” level can be adjusted to other values – if you want so.
All parts are top quality, schematics used are from top manufacturers. Operational Amplifiers are exchangeable – mounted in sockets. We use Texas Instruments INA137PA, DRV134PA.
In the input and output sections are additional RCA sockets. You can connect signal source which does not have XLR sockets.
Bracket of the meter bridge attaches to the existing attachment points (screw holes) of the recorder. This meter bridge does not require special side panels. Meter Bridge can be used either with original Studer stand or without stand – as a table top version. Connection wires can be hidden in the vertical post of the bridge. Connection to the signal source can be done either with RCA or XLR connecting wires.
We provide WORLDWIDE shipping with TRACKING NUMBER.
