Produktinformasjon:
The STM-2X is the ideal choice in many installations where a microphone preamplifier is required, and is the ideal choice where either a toggle-type switch or push-to-talk switch is to be provided for microphone control, particularly if condenser microphones are used.
Power Supply Not Included PS-24AS.
Main Features:
Quiet Switching of Condenser Microphone
Remote Microphone Soft-Switching
Switch a Mic-Level Source to a Mic or Line Level Output
Remote Toggle Switch or Push-to-Talk Button
Adjustable Preset Gain on Microphone Source
Specifications:
Input: 500 ? balanced; 5 k? unbalanced
Phantom:24Vdc; IEC 1938: 1996-12, Filtered
Line Level Output:+4 dBu 150? balanced
