Description
ProAVM MATCH-IT MATCHING UNITS
The MATCH-IT and MATCH-IT2 allow the benefits of inexpensive domestic and semi-professional source equipment to be applied to the professional installation with minimum compromise in sound quality. As well as substantial cost savings, such machines also offer wider choice and availability compared to their professional brethren and, if well chosen, can prove extremely reliable. Mounted as close to the source equipment as possible, the MATCH-IT/MATCH-IT2 translate between the low level, unbalanced signals used by consumer devices and the higher amplitude, more noise-immune, balanced format found in the professional environment. From that point onwards, mains hum and interference from densely packed equipment will be rejected.
Both units are packaged in a robust metal case suited to mounting on rack shelves or in the Canford “Rack-Pak”, beneath woodwork or inside rack cabinets by means of screws, ties or sticky pads. They are supplied with a mains lead, comprehensive instructions and a five year warranty.
MATCH-IT Bidirectional Matching Unit
Provides matching in both the record (balanced to unbalanced conversion) and replay (unbalanced to balanced) directions for one piece of domestic recording equipment, such as a tape or Mini-Disk recorder. The gain of both sections may be individually varied over a wide range that includes 0dB for higher level sources requiring balancing but no amplification.
MATCH-IT2 Dual Unidirectional Matching Unit
Provides matching in the playback direction only, for two domestic sources, such as CD players and tuners. Typically set to +14dB, the gain applied can be varied over a wide range that includes 0dB for higher level sources (e.g. some CD players) which require balancing but no amplification.
This range was formerly known as SBS.
