The primary applications for the IT4A 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 IT4A 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.\u003c\/p\u003e\r\n\u003cp\u003eThe IT4A is fitted with standard 3-pin XLR-type connectors and 3-conductor 1\/4” (6.3mm) phone jacks for LINE IN and ISO OUT so hookup typically requires only standard cables. The use of the Pro Co LOT-P transformer allows the IT4A to provide floating low-impedance outputs with wide flat frequency response ultra-low distortion and no ringing or overshoot to degrade transient response. \u003cbr\u003e\r\n \u003cbr\u003e\r\nThe IT4A’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 Install Sound \u0026gt; Install Speakers \u0026gt; Transformers combine superb audio quality with unsurpassed noise rejection.\u003cbr\u003e\r\n \u003cbr\u003e\r\nThe IT4A 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.\u003cbr\u003e\r\n \u003cbr\u003e\r\n\u003cstrong\u003eFEATURES:\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n    \u003cli\u003eTrue Floating Transformer Isolation for Unbalanced Line-Level Outputs\u003c\/li\u003e\r\n    \u003cli\u003e4 Channels in Single Rack Space\u003c\/li\u003e\r\n    \u003cli\u003eInput Output and Loop-Thru XLR and 1\/4\" (6.3mm) Phone Jack Connectors\u003c\/li\u003e\r\n    \u003cli\u003eIdeal for Portable and Permanent Sound Systems\u003c\/li\u003e\r\n    \u003cli\u003eAll Connectors Accessible From Front\u003c\/li\u003e\r\n    \u003cli\u003eHigh Quality Transformer-Isolated Output\u003c\/li\u003e\r\n    \u003cli\u003eRugged Pro Co Uni-Box Construction Provides Protection and EMI\/RMI Shielding\u003c\/li\u003e\r\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e \u003cdiv data-selenium=\"specWrapper\" class=\"specWrapper\"\u003e \u003ctable class=\"specTable\" border=\"1\" data-selenium=\"specTable\"\u003e \u003ctbody data-selenium=\"specBody\" align=\"left\"\u003e \u003ctr\u003e \u003ctd class=\"specTopic c28 fs14 bold\" data-selenium=\"specTopic\"\u003e Frequency Response \u003c\/td\u003e \u003ctd class=\"specDetail c28 fs14\" data-selenium=\"specDetail\"\u003e 20Hz to 20kHz +\/- .5dB @ 0dBv output\u003cbr\u003e-3dB @ approzimately 85kHz \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"specTopic c28 fs14 bold\" data-selenium=\"specTopic\"\u003e THD (Main Outputs) \u003c\/td\u003e \u003ctd class=\"specDetail c28 fs14\" data-selenium=\"specDetail\"\u003e Less than 0.25% 20Hz to 20kHz @ 0 dBv output\u003cbr\u003eLess than 0.5% 30Hz to 20kHz \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"specTopic c28 fs14 bold\" data-selenium=\"specTopic\"\u003e Input Impedance \u003c\/td\u003e \u003ctd class=\"specDetail c28 fs14\" data-selenium=\"specDetail\"\u003e Greater than 680 ohm @ 1.0kHz\u003cbr\u003eGreater than 680 ohm @ 10kHz \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"specTopic c28 fs14 bold\" data-selenium=\"specTopic\"\u003e Output Impedance \u003c\/td\u003e \u003ctd class=\"specDetail c28 fs14\" data-selenium=\"specDetail\"\u003e Less than 120 ohm @ 1.0kHz\u003cbr\u003eLess than 120 ohm @ 10kHz \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"specTopic c28 fs14 bold\" data-selenium=\"specTopic\"\u003e Voltage Loss \u003c\/td\u003e \u003ctd class=\"specDetail c28 fs14\" data-selenium=\"specDetail\"\u003e Less than 2dB @ 1.0kHz \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"specTopic c28 fs14 bold\" data-selenium=\"specTopic\"\u003e Input Connections \u003c\/td\u003e \u003ctd class=\"specDetail c28 fs14\" data-selenium=\"specDetail\"\u003e XLR (female) and 1\/4 in. phone \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"specTopic c28 fs14 bold\" data-selenium=\"specTopic\"\u003e Output Connections \u003c\/td\u003e \u003ctd class=\"specDetail c28 fs14\" data-selenium=\"specDetail\"\u003e XLR (male) and 1\/4 in. phone \u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd class=\"specTopic c28 fs14 bold\" data-selenium=\"specTopic\"\u003e Weight \u003c\/td\u003e \u003ctd class=\"specDetail c28 fs14\" data-selenium=\"specDetail\"\u003e 4.11 lbs.
