TROUBLESHOOTING
If you experience trouble with the SC-11S1, make the below
checks before thinking the worst. Improper operation can
cause the SC-11S1 to behave in a way that makes you think
something is wrong with the equipment when actually not. If
the trouble cannot be fixed after making the below checks,
contact the place of purchase, your nearest Marantz dealer,
our customer service center or our repair service center.
Power does not turn ON
Is the power cable securely plugged into a power outlet?
Nothing is heard from the headphones or
speakers
1. Is the PRE OUT button on the front panel OFF?
2. Is the PHONES OUT button on the front panel OFF?
3. Is the ATT (attenuation) feature active?
4. Is the input source selected with the INPUT SELECTOR
on the front panel correct?
5. Are you using the player (replaying device) correctly?
6. Are connection cables and speaker cables securely
connected?
7. Volume may have been muted by a protective circuit that
tripped. Try adjusted the volume again.
8. If an error message is displayed, correctly set the ID number
as indicated in the reference table.
Volume differs between left and right
Are the volume (LEVEL TRIM), bass, or treble levels trimmed
differently for the right and left sides? If required, try trimming
again.
Sound is not stereo
The MODE switch on the rear panel may be set to “BI-AMP”.
If the unit is in bi-amp mode, shut the power OFF, set the
MODE switch to “STEREO” and then reactivate the power.
Power must be activated after the MODE switch is set for the
setting to be active.
Record player audio is not heard or contains
a lot of noise
1. Is the PHONO MC button on the front panel set to match
the type of cartridge you are using?
2. Are the connection cables securely connected?
3. Is the grounding wire from the record player connected to
the PHONO GND terminal?
4. Is the cartridge properly connected to the tone arm?
7 Protective Circuits
The unit is equipped with protective circuits to protect the
amplifier circuits and headphones against damage. If a
protective circuit trips, the sound is instantly muted. In this
case, “PROTECT” flashes on the display and the OPERATE
indicator also flashes. To release the protective circuits, switch
the power OFF, and wait for approximately 1 minute before
switching the power back ON again.
At Power ON
For about 8 seconds after the power is switched ON, a
protective circuit trips and mutes the sound to give amplifier
circuits time to stabilize. Once the amplifier circuits stabilize,
the protective circuit releases and audio is enabled.
If Strong Bass Signals Are Input
A protective circuit trips if bass signals of an excessive level
are detected. A protective circuit also trips if an abnormality
caused by such reasons as an amplifier fault is detected in the
power supply circuit.
7 Error Messages
When multiple SC-11S1s are connected by F.C.B.S., the
below error messages may appear on the display. In these
cases, there is a problem with the ID number setting or remote
cable connection. Check the ID numbers and remote cable
as indicated in the below table. For details on how to set ID
numbers, see HOW TO SET ID NUMBERS on pg. 27.
