The TOA Electronics Microphone Input Module- Bal.- 600 Ohms- Lo/Hi-Cut Filters- Mute-Send- Removable Terminal (M-41S) from DJDeals.com is a single-channel balanced microphone input module for the TOA M-8080 series modular mixing matrix systems, providing 600-ohm balanced mic input, switchable Lo-Cut and Hi-Cut filters, and Mute-Send functionality in a plug-in card format.
TOA Electronics Microphone Input Module- Bal.- 600 Ohms- Lo/Hi-Cut Filters- Mute-Send- Removable Terminal (M-41S) Features:
- Balanced 600-Ohm Microphone Input. A standard 600-ohm balanced XLR-compatible input accepts signals from dynamic and condenser microphones, delivering the common-mode rejection required to reject hum and RF interference in commercial audio systems.
- Switchable Lo-Cut Filter. An onboard high-pass filter reduces low-frequency rumble, HVAC noise, and handling noise from microphone signals, improving speech clarity in paging and public address applications.
- Switchable Hi-Cut Filter. A low-pass filter trims excessive high-frequency content and hiss, shaping the microphone signal for optimal intelligibility over loudspeaker systems and distributed paging networks.
- Mute-Send Function. A Mute-Send control allows the module to trigger background music attenuation when the microphone is activated, automating ducking in multi-zone paging systems without requiring external logic controllers.
- Removable Terminal Block. Screw-down removable terminal connections allow the field technician to pre-wire cables before inserting the module, simplifying installation and future module replacement without rewiring.
- Plug-In Card Format. The M-41S slides into standard slots on the TOA M-8080 chassis, enabling a modular, scalable system design with only the input types needed for each specific installation.
- Phantom Power Support. Condenser microphones requiring 48V phantom power can be connected directly when phantom power is enabled from the host M-8080 chassis, eliminating the need for external phantom power supplies.
