Sony HVR-1500A Operating Instructions Manual page 15

When analog audio is selected, the signal input to the
AUDIO IN 2/4 connector is recorded either on channel 2
(when in 2- channel mode) or on channels 2 and 4 (when
in 4-channel mode). That is, in 4-channel mode, the same
analog audio signal is recorded on channels 2 and 4.
Using the REC/PB LEVEL control knobs with the
VARIABLE switch set to REC, it is possible to adjust the
audio levels on the two channels separately.
You can switch the audio recording mode with the REC
MODE menu item (see page 83).
