8 Channel Isolation Transformer, Rack Mt.

BSW PART: IT8A

IT8A
The Pro Co TradeTools IT8A Isolation Transformer Unit provides eight high-quality 1:1 line-level output transformers for applications requiring the high degree of electrical isolation only transformers can provide. The primary applications for the IT8A are in sound reinforcement systems where it may be necessary to break ground loops between pieces of equipment connected with unbalanced lines. For instance, the IT8A can be used to float the unbalanced outputs of an active crossover unit that must drive long cables connected to power amplifier inputs. Transformer isolation in such situations minimizes interference from SCR lighting dimmers, radio transmitters and 60 Hz AC power wiring. Furthermore, the common-mode voltage range of a transformer makes it far more forgiving of improper connections or fault conditions than any electronically balanced or “differential” transformerless circuit. This makes transformer-floated outputs essential for safeguarding portable sound reinforcement systems and installations.

The IT8A is fitted with standard 3-pin XLR-type connectors for LINE IN and ISO OUT, so hookup typically requires only standard microphone cables. The use of the Pro Co LOT-1 transformer allows the IT8A to provide floating, low-impedance outputs with wide, flat frequency response, ultra-low distortion, and minimal ringing or overshoot to degrade transient response. The LOT-1’s dual primary windings allow it to be reconfigured for 1:2 operation if required, providing 6 dB of voltage step-up. Individual GND/LIFT switches provide isolation and buzz-free operation in virtually any environment.

The IT8A’s rugged 16–gauge steel and aluminum “Uni–box” construction enclosure is finished in a durable black texture powder coat finish with black anodized aluminum side channels. Easy–to–read control graphics are incorporated into the Lexan® front and back panel overlays. Inside, the specially designed transformers combine superb audio quality with unsurpassed noise rejection.

The IT8A can be mounted in any standard 19” (482.6mm) rack. Top quality connectors and switches provide trouble-free service even in abusive situations such as remote broadcast and recording operations. The rack-mounting design allows the user to assemble a conveniently packaged expandable isolation system that combines top-quality audio performance with an economical price.
