The TOA A1712 mixer amplifier 120W has a maximum of 9 inputs – up to 6 microphone inputs (XLR/Jack Combo socket) and up to 5 line inputs (line inputs 1, 2 and 5 are XLR/Jack Combo sockets, with 3 and 4 being dual RCA). “MIC 5/AUX 1” and “MIC 6/AUX 2” inputs are switchable between mic or line level. Phantom Power (17VDC) can be provided to any individual or all microphone inputs via the “On/Off” dip switch selector on the rear panel.

The A1712 has two Speaker Output Zones which can be independently selected via the “Zone 1” and “Zone 2” switches located on the front panel.

The TOA A1712 mixer amplifier is equipped with a host of features providing versatility and flexibility at a great price. It is suited for many different Paging & back ground music applications including schools, offices, shops, factories, churches just to name a few.

For more sophisticated equalization external processing equipment can be patched in before the power amplification stage via the “LINE OUT” and “PWR AMP IN” RCA connectors on the rear panel or other equipment such as a delay unit can be connected if required. Alternatively the “LINE OUT” can be used to send the mixed output to a power amplifier.

There is also remote control capability allowing remote control of the Mater volume level and powering the unit on and off.

The A1712 can also be rack mounted with the the optional M25B rack mounting kit.
