MTP40S

Wideband Bodypack Transmitter

MTP40S is an extremely small and light pocket transmitter especially designed for professional wireless microphone applications. Very easy and quick to use thanks to OLED display, dedicated buttons and a joggle selector. MTP40S benefit also of the latest Wisycom RF technology along with an enhanced robustness against noise and inter-modulation.

Improved features:
– New white OLED display (128 x 32 pixels)
– Integrated HW limiter

Enhanced robustness against self-interferences and antenna performances thru a proprietary “intermodulation cancellation” circuit
Miniature design with flexible pcb (no connectors) for extended reliability
Ultra-light metal alloy body (80g without batteries)
User selectable multi-companding systems:
ENR (noise optimized)
ENC (voice optimized)
Battery: 2 AA Alkaline, rechargeable NiMH or Lithium
Autonomy:
> 7h @ 100mW output power
> 10h @ 50mW output power
> 14h @ 10mW output power
Infrared interface for management and firmware update
Easy and quick to setup thru an Oled display gain/freq button and a joggle selector
Extended regulation on Mic input gain: 85dB in 1dB step
Max input level 26dBu (15.5 V clipping) to connect directly to mixers and instruments
48V phantom power to use wired mic thru the PHA48 accessory
