Alto Professional HPA6 - Manual (Page 5)

Through the Aux Inputs, you can use the six channels of HPA6 independently to give individual mixes to six
different musicians. Connect the Aux Sends or Subgroup outputs directly to the Aux Input of HPA6. Then
rotate the Balance control on your HPA6 fully to the left. This will route only the AUX IN signal to the
headphones.
USING MULTIPLE HEADPHONES ON THE SAME CHANNEL
Each channel provides three headphone outputs. These jacks are all connected in parallel. For best results,
please note the impedance information:
• When connecting one headphone to each channel, the minimum impedance of the headphone should
be 100 ohms.
• When connecting two headphones to each channel, the minimum impedance of each headphone should
be 200 ohms.
• When connecting three headphones to each channel, the minimum impedance of each headphone
should be 300 ohms.
INSTALLATION AND CONNECTION
Read the following section carefully. Not paying attention to the input signal level, to the routing of the signal
and to the assignment of the signal will result in unwanted distortion, a corrupted signal or no sound at all.
Power Connection
Use the same fuse as marked on the fuse holder near the power connector. Connect HPA6 to a standard
power outlet using the enclosed power cable.
Audio Connection
The HPA6 uses balanced XLR and 1/4" TRS phones jack.
It can be connected to other units in a variety of
ways to support a vast range of applications without experiencing a signal loss.
