Balanced or Unbalanced?
The A1500.2 / A1500.4 amplifiers have RCA inputs for
unbalanced or balanced (differential) analog audio.
Almost all audio source units / DSPs use unbalanced
audio output connections.
A1500.4 are shipped configured for unbalanced input
operation. If this amplifier is to be used with a balanced
output device, the top cover can be removed and the
unbalanced / balanced switches located on the Class A
voltage amplifier cards should be switched to "balanced".
Do not switch these to balanced if an unbalanced source
is being used.
As such the A1500.2 /
