4. APPLICATIONS
Through the AUX IN inputs you can also use the 6 channels of your HPA6 independently
to give individual mixers to 6 different musicians. Connect the Aux Sends or Subgroups
outputs directly to the AUX IN input of your HPA6. Y ou need a mixer with 6 Aux sends
output or with 6 subgroups such as the Alto L Series mixer . Now rotate the BALANCE
control on your HPA6 fully to the left. IN this way you will exclude the MAIN signal and
only the AUX IN signal will be sent to the headphones.

SOME FINIAL NOTES
1. RACK MOUNTING
The most secure mounting is on a universal 19" rack available from various rack
manufacturers or your Dealer . The HPA6 6-Channel Headphone Amplifier fits into
one standard 19" rack unit of space. Please allow at least an additional 4" depth
for the connectors on the rear panel. Be sure that there is enough air space
around the unit for sufficient ventilation and please do not place your HPA6 the
6-Channel Headphone Amplifier close to high temperature devices such as power
amplifiers etc. to avoid overheating.
2. USING MUL TIPLE HEADPHONES ON THE SAME CHANNEL
Each channel provides 3 Headphone Outputs. These jacks are all parallel connected.
For best results getting from the HPA6, please note the impedance information as
following:
1. For each channel connecting with 1 headphone, the minimum impedance of the
headphone should be 100 ohms.
2. For each channel connecting with 2 headphones, the minimum impedance of
each headphone should be 200 ohms.
3. For each channel connecting with 3 headphones, the minimum impedance of
each headphone should be 300 ohms.
