Input impedance (with 1.0 kohm loads on DIRECT and ISO OUTS) is approximately 333 ohm. DIRECT OUTPUT: Phoenix COMBICON plug-in screw connector wired in paral¬lel with MIC IN provides signal to feed mixer input. Pro Co Sound 225 Parsons Street | Kalamazoo, MI 49007 800-253-7360 ISOLATED OUTPUT: Male 3-pin XLR-type connectors provide floating transformer-isolated low-impedance outputs to feed mixer inputs. Recommended load impedances: 1.0 kohm. GND/LIFTS: GND position connects pin 1 of MIC IN/DIRECT OUT to pin 1 of ISO OUT. LIFT position “floats” ISO OUT. Used to reduce hum and buzz by eliminating ground loops and providing proper grounding for various conditions. » www.procosound.com APPLICATION INFORMATION NOTES: 1. For safety reasons, all equipment with 3-wire AC line cords should be connected to properly grounded receptacles. If all mixers are grounded properly, GND/LIFT switches should be set in the LIFT position for minimum hum and buzz. If this setting does not minimize hum and buzz, it may be indicative of poor grounding quality or improperly wired AC receptacles. Such conditions may be hazardous and should be investigated. If a GND/LIFT switch seems non-functional, check the wiring of all mic cables plugged into the unit. Cables with a jumper between pin 1 and the connector shell can defeat the GND/LIFT switches. 3. Direct boxes receiving inputs from AC-line-powered sources such as keyboards or stage amplification should have their GND/LIFT switches set to LIFT and the source equipment line cords properly connected to grounded 3-wire receptacles whenever possible. (See note 1). 4. Because of the use of transformers, DC current cannot be passed from an ISO OUT to the MIC IN. This effectively blocks phantom power such as may be required by condenser microphones and some direct boxes. Phantom power must be provided by the mixer connected to the DIRECTS, or by a suitable outboard power supply connected between the microphone and the MIC IN. 2. Microphones require a ground connection somewhere in the signal path. For this reason it is suggested that a properly grounded mixer always be connected to the DIRECT OUTPUT.
