Connecting a graphic equalizer and power amplifiers
Connecting a graphic equalizer
The AMP IN and the PREOUT connectors are attached with
jumper plugs. When connecting a graphic equalizer, remove these
jumper plugs before connecting the audio connection cables.
1. Remove the jumper plugs.
2. Connect a graphic equalizer.
Notes:
• Keep the jumper plugs so that you will not lose them.
• When the connectors are not in use, replace the jumper plugs.
Connecting power amplifiers
Using auxiliary power amplifiers allows you to listen at louder
volumes than with the TX-DS989 alone. If power amplifiers are
used, connect each speaker to the corresponding power amplifier.
1. Remove the jumper plugs.
2. Connect the power amplifiers.
Notes:
• Keep the jumper plugs so that you will not lose them.
• When the connectors are not in use, replace the jumper plugs.
