HeadLite 3+
1 +Power channel; 3 Standard Channel
The +Power Channel provides around 450mW into
50Ω
headphones, and the Standard Channel
around 150mW into
50Ω (see
Power Output
in
Specifications). The HeadLite3+ comes with one
+Power channel and three Standard, but can have +Power modules fitted to the other channels.
Connections
The headphone outputs are on three pole ¼" jacks, tip=left, ring=right, sleeve=0V. The front and
rear outputs for each headphone amplifier are connected in parallel. The output circuitry is de-
signed to drive down long lines with minimal high frequency loss. If two or more pairs of head-
phones are to be driven by one output, they should be of the same type and impedance. If they
are different (eg. low and high impedance), power sharing will not be even and their volume may
be significantly different.
2 Input Select
With up to four inputs connected to the unit, decide which headphone amplifier output you wish to
use. To select the input(s) you wish to listen to, rotate the selector switch to the appropriate point:
AB means inputs A and B on the Left and Right output respectively;, AA means input A on both
Left and Right, BB means input B on both Left and Right etc. Plug your headphones in and adjust
the volume to an acceptable level.
4 Volume Control
The HEADPHONE VOLUME control adjusts the signal level going to the amplifier. This control
allows independent volume control of each amplifier's output.
