Operating Your Amplifier: Rear Panel Sockets And Switches - EM Acoustics AD-9 User Manual

AD-9 Operating Instructions
Operating Your Amplifier: Connections & Rear Panel Controls
Output SpeakON
There must be no shared connections between channels.
Negative output terminals must not be joined together as they are not both at
ground potential. Connecting them together will damage the amplifier and void
the warranty!
As the currents involved are very high, and to ensure best performance, the speaker cables
should be kept as short as possible and conform to the following minimum requirements:
AD-9: 25A into 4 Ohm speaker loads
Link switch: Press this switch to link the input of the channel to its immediate left.
The front panel attenuators will still operate independently when channels are linked.
PRC switches: Each channel of the amplifier may be power limited independently
using these pairs of switches in three stages, offering 2, 4 and 6dB of Power
Reduction Control.
The settings for these switches are on the rear panel for quick reference.
