Professional Sound On Your Station

The audio level in any sound broadcasting system must be controlled to prevent over modulation. The current trend is for broadcast stations to transmit a constant level of audio optimised to 100%. The Aareff Limiter Compressor is specifically designed to achieve constant 100% modulation without any over modulation using an FM broadcasting transmitter. The result is a professional sound on your station output with all music and speech inputs. This unit is fully enclosed in aluminum and steel casing measuring 279 x 190 x 89 mm.

Both of the following units come with a power supply for connection to any AC voltage between 90 and 260 V AC. Operation is also possible from 11 to 14V DC, ideal of vehicle battery or low voltage systems.
