One stereo source on a 5-pole captive screw connector feeds three stereo outputs, all of which will take balanced or unbalanced wiring. Gain is set by DIP switch rather than a trim pot, which is the sensible choice for a device that gets set once and forgotten: with the switch matched to the output wiring the unit runs at unity, and a deliberate mismatch yields a fixed +6 dB lift or a 6 dB drop, which is often exactly what is needed when a balanced console has to drive an unbalanced amplifier input. Frequency response is flat to ±0.05 dB across the band and channel-to-channel gain error is held to ±0.1 dB.\u003c\/p\u003e\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThree stereo outputs, balanced or unbalanced, from one stereo input.\u003c\/li\u003e\n\u003cli\u003eFrequency response of 20 Hz to 20 kHz within ±0.05 dB, THD+N of 0.03% at 1 kHz.\u003c\/li\u003e\n\u003cli\u003eSignal to noise better than 90 dB balanced at maximum output.\u003c\/li\u003e\n\u003cli\u003eCommon mode rejection above 75 dB across 20 Hz to 20 kHz.\u003c\/li\u003e\n\u003cli\u003eHigh input impedance, over 50k ohms unbalanced and over 25k ohms balanced, DC coupled.\u003c\/li\u003e\n\u003cli\u003eDraws only 12 VDC at 0.2 A max from an external Everlast 6 W supply.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003eLectern and podium audio splits, classroom and meeting room feeds to an amplifier plus a recorder plus assisted listening, projector pole mounts where a local audio tap is needed, and rack corners where a full-width distribution amplifier would be overkill.
