No gimmicks or frills, just the right stuff.
Floating transformer balanced XLR output for maximum isolation. SPKR Mode handles amplifiers up to 600W RMS. Hi cut filter reduces distortion. A ground lift eliminates hum and buzz. Rugged Uni box construction. Switches and connectors are recessed to prevent damage. Passive design requires no batteries or phantom power.
