The LD410 Audio Line Driver & Level Matcher from Whirlwind is a tool designed to match audio equipment signal levels. It is both a professional 10 to +4dB to -10dB level converter and a multi-channel distribution amplifier.

This unit features (8) input channels using low-noise preamplifiers with 14dB input pads to attenuate high input signals and (8) output channels with gain controls, LED metering, and mute buttons. It has (4) channels dedicated to conversion -10dB to +4dB (RCA inputs jacks to male XLR outputs) and (4) channels dedicated to +4dB to -10dB level conversion (female XLR inputs to RCA output jacks).

Assignable signal routing jumpers inside this model permit the creation of multiple distribution amplifiers by allowing multiple outputs to receive signals from a common input. The internal power supply can be set for 115VAC or 230VAC by changing internal jumpers. This unit is rackmountable and occupies 1U of rack space.
