DA103

The NANOAMP MIC and Line level 1X3 Distribution Amplifiers consist of independent +22dBm
servo balanced outputs in 1/3 RU enclosure. The master gain controls have three output trim
pots. The DA103 accepts a line level input, balanced or unbalanced audio at –20, -10 o
+4dBu nominal and provides a line level output at +4dBm nominal level to balanced o
unbalanced output lines. The DA103 input/output connectors are two piece solderless
“Phoenix” types, individual for each input and output line.

The DA103 accepts a maximum line input level of +22dBu to high impedance
(20Kohms) balanced instrumentation amplifier input (A1) and drives three servo balanced 600­ohm (minimum load) outputs (A3, A4, A5) up to +22dBm maximum. An internal input gain
setting jumper plug optimizes the input stage gain, noise and headroom for nominal inputs at ­20, -10 or +4dBu. The servo-balanced outputs automatically detect single-ended (one side
grounded) loads; remove the drive signal from the grounded output and double the signal
applied to the ungrounded output thus maintaining equal gain for both types of loading.

Unit protection kit which consists of a set of side plates with attached
side brackets. The side plates protect the front panel controls and the
rear XLR connectors from impact damage, and for attachment to carry
strap (not included); the slide brackets provide ease of access and
exchange of the power assemblies i.e. PPA, DCA, or BBU.
