~From the manufacturer's website~
- The volume is a coaxial trim/level integrated unit. The design is dense and compact, despite its size.
- Equipped with a mic/line selector switch and a phantom power ON/OFF switch for each channel. (Phantom power is turned ON by raising the dip switch.)
- Balanced output via a cannon-type XLR connector. Equipped with a BUS terminal, it can be expanded to 10 inputs, 1 output, etc. by cascading.
