If you encounter a problem, please review the items in the following
checklist. Also be sure to thoroughly check all other connected compo-
nents such as speakers, equalizers, amplifiers, VCR, TV, CD player, etc.
Problem
Possible Cause and Solution
Power does not come on
Check line cord to ensure good connection to the AC outlet and to the
receptacle on the SDP-3 rear panel. Check to make sure that the SDP-
3 rear panel power switch is ON.
No audio
Check the Status menu (under DISPLAY ADJUST: ON-SCREEN or
FRONT PANEL menu — or press and hold Record/Zone 2 on the
remote and press OSD ON) to verify that audio is being received.
Remote control not working
Check batteries to be certain that they are inserted correctly with proper
polarity. Make sure that the infrared sensor on the SDP-3 front panel is
not obstructed. See "If all else fails..." on the following page.
No output
Make sure that signal is coming into the SDP-3. (Check the Status menu
by pressing and holding Record/Zone 2 on the remote, then pressing
OSD ON. This menu will display input level meters and sample rate, if
applicable.)
Increase VOLUME using the remote control and check Front/Back and
Left/Right BALANCE.
Check the SDP-3
MUTE controls to make sure they are not engaged.
Check all other equipment settings and connections and verify that the
amplifiers being fed by the SDP-3 are operational.
Remember that the SDP-3 mutes the output to any speakers which are
not configured in the Setup menu. If speakers are added to (or removed
from) your system, the Speaker Configuration menu must be altered
accordingly.
Center Channel only plays
Check to see if your HiFi VCR has dropped out of tracking — readjust.
Your VCR Stereo/Mono/L-R switch may be in the wrong position — set
it to Stereo.
Muffled sound in L&R channels
When no center channel is used, CENTER must be configured for
NONE in the Setup Speaker Configuration menu.
Center channel sound muffled
The center channel amp may be connected to the subwoofer jack on the
SDP-3 rear panel. Reconnect to Center Output jack.
No Input Level Meters
The meters will only appear when adjusting the Gain parameter of a
selected, active input, or when the Status menu is displayed.
