Whirlwind MIPAID 2 Gang Media Input Wall Plate with Power Supply, White

The Whirlwind MIPAI media input plates are active, dual input mixer plates designed to combine line and microphone input sources into a single line level balanced output that can be sent over long distances to remote audio processing equipment. Applications include gymnasiums, banquet halls, conference centers and others where local volume control is desired for the source material. The MIPAI is available in a one gang wall plate with black or clear brushed aluminum finish and in a two gang white decor insert. Each Whirlwind MIPAI plate is a standalone two channel mixer with one balanced mic level input via a 3 pin female XLR and a stereo aux input connected through a 3.5mm TRS unbalanced jack that is summed to mono. Separate level controls are provided for each input and deliver enough gain to drive modern power amplifiers to full output. A bass cut switch is provided on the mic input for reducing rumble and handling noise. An additional line input appears on the rear panel screw terminals for connecting up to two more MIPAI plates in a daisy chain type configuration, i.e., output of the first to the input of the second, output of the second to the input of the third and output of the third to the processing electronics. All three plates are summed together and all six level controls can adjust their respective inputs up to the maximum output drive level of +22dB. If inputs from multiple MIPAI plates are used at the same time caution must be taken to keep the total summed output level below +22dB or sum bus clipping can occur. Each MIPAI has two LEDs that indicate signal levels of -10dB and +10dB. The last MIPAI in the chain will show signal level on its LEDs even if no input is being applied to that plate. All three plates can be powered from a single supply located in the equipment rack. The Whirlwind MIPAO or MIPAT output termination boxes can used to connect MIPAI plates to processing electronics. Audio output is via a 3 pin male XLR or screw terminals. A2.1mm power input jack loops the wall power supply to the MIPAI screw terminal connections. Electrical backbox depth of 2.5" minimum recommended for gangable box type, 2.125" for utility box type.Output connections on the rear circuit board are 8 position, 3.5mm screw type, removable plugs (Phoenix 1984073 or equivalent). The rear panel line input is shipped with a shorting jumper termination. Remove the jumper to connect another MIPAI.
