Set the meter to its 70 dB dial setting with SLOW response and C-weighting,
held away from your body at your listening position (mounting the SPL
meter on a camera tripod makes this easier). You can point the SPL meter
at each speaker as it is being measured; however, positioning the meter
in a fixed position pointing at the ceiling is easier and probably produces
more consistent results.
Increase the master volume control on the unit until the meter reads 75 dB
(+5 dB on the meter scale) when playing the test tone through one of the
front speakers. Then, use the individual channel adjustments on the SPEAKER
LEVEL SETUP menu to adjust each of the individual speakers, including the
subwoofer, to the same 75 dB on the SPL meter.
NOTE: Due to meter weighting curves and room effects, the actual
level of the subwoofer may be slightly higher than you measure. To
compensate, Dolby suggests setting the subwoofer several dB lower
when calibrating with an SPL meter (i.e. set the subwoofer to read 72
dB on the meter instead of 75 dB). Ultimately, the proper subwoofer
level must be determined by personal taste and some listeners prefer
to set it above 75 dB for film soundtracks. Exaggerated bass effects
come at the expense of proper blending with the main speakers and
place stress on the subwoofer and its amplifier. If you can localize
bass from the subwoofer, the subwoofer level may be too high. Music
can be useful for fine-tuning the subwoofer level as excessive bass is
readily apparent. The proper setting will generally work well for music
and movie soundtracks.
Remember the setting of the master volume control used during this calibration.
To play a Dolby Digital or DTS soundtrack at the reference volume level,
simply return to that volume setting. Note that most home theater listeners
find this setting to be excessively loud. Let your own ears be the judge for
deciding how loud to playback movie soundtracks and adjust the master
volume control accordingly. Regardless of your listening levels, using an SPL
meter to calibrate equal levels for all speakers in the system is recommended.

The SPEAKER DISTANCE SETUP menu, which is reached from the MAIN
menu, allows you to set the delay for individual speakers. This ensures that
the sound from each speaker arrives simultaneously at the listening position,
even when the speakers are not all placed at equal distances from the
listener. Increase the delay to speakers located closer to the seating area
and decrease the delay to speakers located farther from the seating area.
The Audio Configuration will determine which speakers are displayed in
the Speaker Distance Setup menu.
This Rotel processor makes setting the delay time for each speaker very
easy. Simply measure the distance (in feet or meters) from your seating
position to each speaker in your system. Set the measured distance in the
line for each speaker. The menu provides a line for each speaker configured
in your system and gives a range of settings up to 33 feet (10.06 meters)

in 0.25 foot (0.075 m) increments with each increment equivalent to an
additional delay of 0.25 ms.
To change a setting, place the highlight on the desired line using the Up/
Down arrow buttons and use the Left/Right arrow buttons to increase or
decrease the delay. To return to the MAIN menu, press the BACK button or
select "BACK" on the OSD. Press the SETUP button or select "EXIT" on the
OSD to exit setup and return to normal operation.

This SYSTEM SETUP menu, reached from the MAIN menu, provides access
to several miscellaneous settings as follows:
LANGUAGE: Selects a language for the On Screen Display.
IR REMOTE CODESET: The RSP-1576 has two IR codesets and can be changed
in the event there is a conflict of IR codes with other Rotel products.
NOTE: After changing the IR REMOTE CODESET the remote must
also be changed to continue using the remote control. Push and hold
the TUNER button and 1 (or TUNER and 2 for codeset 2) at the same
time and hold for approximately 5 seconds until the backlights on the
remote control blink on then off then release both buttons. This sets the
remote control to use codeset 1 (or codeset 2 if TUNER and 2 are held).
PEQ FUNCTION: Turns the PEQ function On or Off.
DISPLAY: Sets the information shown on the main HDMI OSD and front VFD
display. Settings are "Off", "HDMI Only", "VFD Only" or "HDMI And VFD".
POWER OPTION: Access to configuration of Off Timer, Max Power On
Volume, Power Mode and Signal Sense Input.
