Adjusting the AV 5150
The key parameters of the AV 5150 can be adjusted to suit the room, and
the system with which it is used, using the switches which can be accessed
by removing the panel.
Removing the panel
The AV 5150 gain control and option switches are protected by a metal
panel, which is located on four pins. To remove the panel pull it gently
outwards.
To refit the panel line up the four pins on the metalwork with the four
mounting bushes on the door, and push it firmly back into place.
Adjusting the frequency response
The upper frequency response of the AV 5150 (low pass filter) is set by the
left-hand bank of switches. The low pass filter should be set to
complement the low frequency response of the main speaker system. Very
small main speakers will need the AV 5150 to respond to higher
frequencies than large main speakers.
Set the switches as follows, where a switch is shown in black:
