The LA-80MKII is an 8-channel unbalanced-to-balanced line converter designed for professional audio installations and studio environments. It provides a flexible solution for integrating a wide range of audio equipment while maintaining reliable signal transmission and high audio quality.Flexible Signal ConversionThe LA-80MKII is built for studio-quality conversion of consumer -10 dBV unbalanced signals to professional +4 dBu balanced line levels. With eight channels of unbalanced-to-balanced conversion, XLR and RCA connectivity, LED signal indicators, and front-panel level controls, it enables precise level matching across studio, broadcast, streaming, and AV installation applications.Audio Distribution Amplifier FunctionThe LA-80MKII can also operate as an audio distribution amplifier (ADA), allowing unbalanced input signals to be distributed to multiple balanced outputs. Supporting 1-in/8-out or dual 1-in/4-out configurations. Ideal for multi-recorder feeds, signal distribution, and multi-zone audio routing.Main Features:8 channels of unbalanced-to-balanced conversionLED indicators for signal presencePer-channel trim controls for fine level adjustment within +/-12 dBADA: Audio Distribution Amplifier- Unbalanced input signals can be distributed to multiple balanced outputs- Configurable for various distribution setups, such as 1-input/8-output or dual 1-input/4-output systemsCompact 1U rack-mount sizeNominal unbalanced input level: -10 dBVNominal balanced output level: switchable +4 dBu / -20 dBuGND LIFT switch on balanced connectors to reduce ground loop noise when connecting multiple devicesGND ALL LIFT switch for rack-level ground loop mitigationEquipped with a 3-prong AC power outlet independent of the main power switchSpecifications:Unbalance to Balance – Input (Unbalanced)- Connectors: RCA pin jack x 8- Input Impedance: 23k (all INPUT LINK switches are OFF)- Input Impedance: 2.8k (all INPUT LINK switches are ON)- Nominal input level: -10dBV +/-1dB- Maximum input level: +9dBV- Indicator detection level (unbalanced input): -38dBV or more (OUTPUT LEVEL switch set to +4dB to -20dB)Unbalance to Balance – Outputs (Balanced)- Connectors: XLR-3-32 equivalent x 8 (1:GND2:HOT3:COLD)- Output Impedance: 94- Nominal load impedance: 10k- Minimum load impedance: 600- Nominal output level: +4dBu, +/-1dB (OUTPUT LEVEL switch set to +4dBu)- Nominal output level: -20dBu, +/-1dB (OUTPUT LEVEL switch set to -20dBu)- Maximum output level: +24dBuGeneral Specifications- TRIM range: +/-12dB- Power: AC 100-240V, 50/60Hz- Power consumption: 6W- Weight: 3.0kg- Dimensions: 482.6 x 44.5 x 295 mm (W x H x D, including protrusions)- Note: 0 dBV = 1 Vrms, 0 dBu = 0.775 VrmsAudio Performance- S/N ratio: 90dB Nominal input and output level, 20 kHz LPF, A-WTD, OUTPUT LEVEL switch set to +4dBu- S/N ratio: 87dB Nominal input and output level, 20 Hz HPF + 20 kHz LPF, OUTPUT LEVEL switch set to +4dBu- Total harmonic distortion: 0.007% or less (1kHz, nominal input and output level)- Frequency response: 20 Hz 100 kHz +/-3dB (nominal input and output level)- Crosstalk: -90dB or more (1kHz, nominal input and output level, terminated with a 600 load)Compliance- RoHS compliant- Specifications and appearance are subject to change without notice
