HA75-DAC HEADPHONE AMP
Hafler
5
If you are using the HA75-DAC in the studio, it is equipped with balanced
XLR female inputs that follow the AES standard with pin-1 (ground), pin-
2 (+) and pin-3 (-). These are paired with the RCA connectors. Use the
selector switch on the rear panel to toggle between the unbalanced RCA
inputs and the XLR inputs. Only one source can be selected at a time.
Also, available are two sets of RCA connectors labelled as THRU
and TUBE OUT. The THRU outputs are un-buffered and function as a
simple pass through (
VOX or FOCUS will have no effect
). The TUBE
OUT delivers the signal after it has been processed by the HA75-DAC.
This can be used to position the HA75-DAC in between a preamp and
power amp to add a warm tube character to the signal path. In the studio
it can be applied to recordings to 'warm-up' stale digital tracks or give
instruments and voice added character, particularly if pushed hard. Be
careful! The HA75-DAC is a powerful beast and can easily overload the
input of a mixing desk if care is not taken.
