The SPA-12 is a multi-purpose Mic / Line mixer with emphasis on conference applications. Very compact and very intuitive to use, the device has 6 mic / line inputs and 4 outputs that also make the SPA-12 a perfect device for zoning.
24 V phantom power is available on each channel for electret microphones.
Channel 1 has priority and the attenuation setting can be adjusted on the rear panel. Three stereo source inputs are available using RCA connectors for AV devices or BGM devices.
The SPA-12 offers a main stereo output plus a mono output with independent volume control. A separate Mic output can be used for monitoring by selecting the microphone signals only.
The SPA-12 can operate with 24 VDC.
