FUSE HOLDER / VOLTAGE SELECTOR. Please make sure that your local voltage matches the voltage indicated on the unit, before you attempt to connect and operate the POWERPLAY PRO. Blown fuses may only be replaced by fuses of the same type and rating.
MAINS CONNECTION. Use the enclosed power cord to connect the unit to the mains. Please also note the instructions given in the “INSTALLATION” chapter.
AUDIO IN. These are the audio inputs of your POWERPLAY PRO, available both as balanced 1/4" jack and XLR connectors.
AUDIO OUT. These are the audio outputs of your POWERPLAY PRO. Matching phone jack and XLR connectors are wired in parallel.
HEADPHONE OUT 1. These are the headphone outputs of channel 1. HEADPHONE OUT 2. These are the headphone outputs of channel 2. HEADPHONE OUT 3. These are the headphone outputs of channel 3. HEADPHONE OUT 4. These are the headphone outputs of channel 4.
5. APPLICATION
5.1 Using the main inputs
Connect a program source to the rear panel MAIN inputs and connect the headphone cable to one of the appropriate outputs. Turn up the INPUT LEVEL and the BALANCE controls to center position. The INPUT LEVEL control is used to increase or decrease the general volume of all headphones controlled via the MAIN inputs, while the individual OUTPUT LEVEL controls are used to adjust the desired channel volume.
5.2 Using the AUX IN inputs
Basically, the AUX IN inputs are used to add an additional input signal to the master signal, with the corre- sponding BALANCE control determining the volume ratio between the two signals. The aux function supercedes the previously required monitor mixer and allows for an application that is frequently used in practice.
Example: suppose a vocalist wants to record a vocal track that is to be added to already existing instrumental tracks. Up to now, it has been common practice that the vocalist listens to the playback by pressing a headphone pad against one ear, while controlling his/her own voice with the other – free – ear.
This kind of application can be achieved much more easily and conveniently with the POWERPLAY PRO. The playback signal is inserted via the MAIN inputs, and the preamplified vocal signal is applied to the AUX connector. The associated BALANCE control is adjusted so that the vocalist hears a perfect mix of both backing tracks and vocals, with the OUTPUT LEVEL control determining the overall volume level.
Owing to the four independent channels of the POWERPLAY PRO, four individual mixes for four musicians can be achieved. If this is not enough, you can interface and link any number of POWERPLAY PROs using the MAIN outputs.
