INTRODUCTION
Thank you for selecting the US Audio DA-2. The DA-2 is a
2- channel, line-level, audio signal distribution amplifier.
Each channel provides four electro nically balanced XLR
outputs with individual volume controls. The audio
performance is of the absolute highest quality possible and
at a reasonable price point, making it an excellent value.
Great care was taken in the design so that the DA-2 can
fulfill any distribution requirement, from professional disk
and tape duplication to power amp input distribution. With
the impedance of the active balanced XLR inputs set at
1Meg Ohms, several units can be par alleled for virtually
unlimited outputs. The DA-2 can provide up to 18dB of
gain allowing operation as a -10dB to +4dB converter.
Other features include clip and signal LEDs, a headphone
monitor circuit and a "combine" switch which configures
the DA-2 as a one by eight distribution amp.
