Installation
5. You may use a pink noise test signal and RTA analyzer for this procedure
(one channel), but ultimately your listening preferences should be of higher priority.
R-88Sub:
1. If your R-88Sub is located less than 5 feet (1.5 m) from the closest R-800, set its
BGA-2500's Phase control knob at 0°. If this distance is further than 5 feet (1.5 m),
set the Phase control knob at 90°.
2. Set Crossover switch to Variable and set Crossover Frequency control knob at 80
Hz.
3. Set Level potentiometer at about 75% of max level or around the 2 o'clock position.
4. Sit in the primary listening location as described above for R-800.
Now you are ready to run level calibration sequence that should be provided by your
processor or receiver's internal generator. Refer to your system's electronics manual
for this. Run the level setting sequence. Your R-800 left and right levels should be at 0
dB. Normally your R-400C center channel level setting should be at 0 dB or slightly
higher. The subwoofer level setting would depend on the number of subs that you use,
their location, room parameters and your location in the room. The levels for surround
channels would depend on speakers that you use, and their distance to the listening
position. After the level setting is completed we recommend listening to your test/demo
surround sound material to verify these settings. You may want to fine tune the levels
based on your actual listening experience. You may also use a microphone and RTA
analyzer for this procedure to accurately verify levels.
If your subwoofers are further than 5 feet (1.5m) apart from the main R-800 speakers,
we recommend using a signal with sustained bass levels or 50-80Hz sine signal and
adjust the Phase Control knob on R-88Sub's amplifier so that the bass level is
maximum at the listening position. Then run level calibration procedure again, since
you may want to reduce subwoofer's level after phase setting has been optimized.
