Adjusting the output impedance
The four switches of the right-hand bank control the power amplifier
output impedance, to increase or reduce the damping of the loudspeaker
drive units. A larger room will often require more bass damping.
Impedance Setting
0 Ω
1 2 3 4 5 6 7 8
-0.5 Ω
1 2 3 4 5 6 7 8
-1 Ω
1 2 3 4 5 6 7 8
-1.5 Ω
1 2 3 4 5 6 7 8
-2 Ω
1 2 3 4 5 6 7 8
Note that decreasing the impedance increases the damping.
Protecting the speaker
Switch 6 brings a soft clipper into the bass circuit path. Use this if you
frequently play the system very loud. It allows very impressive sound
effects while protecting the drive units against extreme overdrive.
Setting Setting

Inverting the phase response
Switch 7 inverts the phase response. Use this if the main system power
amplifier or speakers are inverting. It may also give better results if the
5150 is at the opposite end of the room from the main speakers.
