TOA M-11S T Microphone Input Module with Mute-Receive for 900 Series Amplifiers, Removable Terminal Block

The TOA M11S is for balanced, low impedance mics. Responds to mute bus activation, normally-on or normally-off.

Features:

• High and Low Cut Filters for tone control, 4.2kHz and 330Hz, 6dB / octave.
• Phantom Power, +22VDC for condenser-type microphones. Activate by default, cut Jumper J1 to disable.
• Responds To Mute Bus Activation, via Mute SEND module or switch-closure.
• Responds To Both Mute Bus #1 And Mute Bus #2 By Default (cut jumper(s) to disconnect individual mute bus).
• Two Mute Response Modes (cut jumpers to configure):
  • 1. Normally-ON - turns OFF during mute activation (most common)
  • 2. Normally-OFF - turns ON during mute activation (functions as an ON/OFF switch, useful for zone-paging microphones in multi-amplifier systems)
• Connector: removable terminal block
