3. APPLICATIONS
3. APPLICATIONS
3.1 Using the MAIN inputs
Connect a program source to the rear panel MAIN inputs and connect the headphone cable with one of the
POWERPLAY PRO outputs. Turn the INPUT LEVEL and the BALANCE controls to their central positions. The
INPUT LEVEL control is used to increase or decrease together the volume of all the headphones which are
being controlled via the MAIN inputs. The individual OUTPUT LEVEL controls are only used to adjust the
desired channel volume.
3.2 Using the AUX IN inputs
The AUX IN inputs are basically used to mix in an additional input signal with the master signal, while the
corresponding BALANCE control adjusts the volume ratio between the two signals. The Aux function replaces
the monitor mixer which was necessary up to now, and so allows for a type of use which occurs frequently in
practice.
Suppose e.g. that a singer has to add a vocal track to an existing playback. Up till now it was usual for the
singer to listen to the playback by pressing a headphone pad against one ear, while using the other ear to
control his/her own voice. With the POWERPLAY PRO this application becomes much simpler and much
more comfortable. The playback signal is played in via the MAIN IN inputs and the pre-amplified vocal signal
added via the AUX connector. The associated BALANCE control is adjusted so that the singer hears a perfect
sound volume mix of both the playback and the vocals, with the OUTPUT LEVEL control determining the
overall volume level.
The four independent channels permit the separate recording and mixing for four musicians. Should this not be
enough, you can interface and link as many POWERPLAY PRO machines as desired using the MAIN OUT
outputs.
