LA-80MKII

Eight-Channel Level Conversion
Convert eight unbalanced audio signals to balanced outputs for integration between consumer-level sources and professional audio systems.

RCA Inputs and Balanced XLR Outputs
Connect unbalanced source equipment through RCA inputs and route balanced signals to mixers, recorders and installed audio equipment through XLR outputs.

Individual Channel Trims
Adjust each channel within a ±12 dB range to match levels between connected devices.

Selectable Output Levels
Choose +4 dBu or -20 dBu nominal balanced output levels to accommodate different receiving equipment.

Flexible Audio Distribution
Distribute an unbalanced input to multiple balanced outputs. Configure a single eight-output distribution system or two independent four-output systems.

Signal Presence Indicators
LED indicators provide a visual check of signal activity for easier setup and monitoring.

Ground-Lift Controls
Balanced-connector ground-lift switches and a GND ALL LIFT switch help reduce ground-loop noise in interconnected systems.

Independent AC Convenience Outlet
A three-prong AC outlet remains independent of the main power switch for powering connected equipment.

Compact Rackmount Design
The 1U chassis accommodates eight conversion channels in studio racks and fixed installations.
