TASCAM / LA-80 MKII Unbalanced/Balanced Line Converter

An unbalanced/balanced line converter with eight built-in circuits that convert unbalanced inputs to balanced outputs.

~From the manufacturer's website~
● 8 unbalanced to balanced conversion channels
● Unbalanced nominal input level: -10dBV
● Balanced nominal output level: 4dBu/-20dBu switchable
● Signal presence indicator
● Unbalanced input signal can be distributed to balanced outputs (ADA: Audio Distribution Amplifier)
● Various audio distribution configurations are possible, such as 1 input/8 outputs or 1 input/4 outputs x 2 channels
● Semi-fixed trim for fine adjustment of signal level within a ±12dB range per channel
● Balanced terminal GND LIFT switch for preventing ground loops when connecting multiple devices
● GND ALL LIFT switch for preventing ground loops when rackmounted
● TASCAM standard 1U rackmount size
● 3-prong power outlet not linked to the power switch

[Differences from the LA-80]
- Includes a signal presence indicator.
- The variable range of the semi-fixed trim for fine-tuning the signal level has been changed from ±6dB to ±12dB.
