Machine is for display purposes and not part of the sale! 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" 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. 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.
