If you experience trouble with the PM-11S1, make the below

checks before thinking the worst. Improper operation can cause

the PM-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.

1. Is the power cable securely plugged into a power outlet?

2. If the OPERATE indicator on the display is flashing a red

color, a protective circuit has tripped. Shut power OFF, wait

a few minutes and then reactivate the power.

* Nothing is heard from the speakers.

1. Aren’t the SPEAKER A and B buttons on the front panel in

the OFF position?

2. Isn’t the attenuation feature (ATT) active?

3. Isn’t there trouble in the input source selected from the

INPUT SELECTOR knob on the front panel?

4. Are you using the player (replaying device) correctly?

5. Are connection cables and speaker cables securely

connected?

6. Volume may have been muted by a protective circuit that

tripped. Try adjusting the volume level again.

7. If an error message is displayed, correctly set the ID number

as indicated in the table under “Error Messages”.

* Volume level differs between left and right

channels.

Volume, bass and treble level may be trimmed differently for

the left and right channels. Try trimming again.

* Stereo sound is not heard from the speakers.

The operating mode switch on the rear panel may be set to

“BI-AMP”. Shut power OFF, set the switch to “STEREO” and

then reactive the power. Power must be activated after the

operating 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 the type

of cartridge you are using?

2. Are 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?

TROUBLESHOOTING

7 About Protective Circuits

The PM-11S1 is equipped with protective circuits to protect

the amplifier circuits and speaker system against damage. If a

protective circuit trips, the sound is instantly muted. In this case,

either “PROTECT” flashes on the display or the display panel

goes out and the OPERATE indicator on the display flashes a

red color.

• At Power ON

For about 8 seconds after power is activated, 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.

• In the Event of Overcurrent

A protective circuit trips if current of a certain level is detected,

which can happen if excessive signal flow is input to the

amplifier or if the PM-11S1 is connected to a speaker system

of less than 4 Ω impedance. A protective circuit can also trip if

a speaker cable accidentally shorts. In these cases,

“PROTECT” flashes on the display and, approximately 8

seconds later, the sound is automatically muted and the

protective circuit is released. Therefore, readjust the volume

level to resume normal use.

If overcurrent is detected because of trouble with the amplifier,

the OPERATE indicator on the display flashes a red color and

power shuts OFF.

• If Strong Bass Signals Are Input

A protective circuit trips if bass signals of an excessive level

are detected. In this case, “PROTECT” flashes on the display

and, approximately 8 seconds later, the sound is automatically

muted and the protective circuit is released. Readjust the

volume level to resume normal use. If these strong bass signals

continue or if excessive DC voltage is detected because of

trouble with the amplifier, the OPERATE indicator on the display

flashes a red color and power shuts OFF.

• If the Power Amplifier Overheats

A protective circuit trips if the temperature of the main amplifier

rises above a certain level, which can happen if excessive

signal flow is continually input into the amplifier. Temperature

can also exceed the trip level of the protective circuits if the

vents on the top of the PM-11S1 are covered or if the PM-

11S1 is installed on a cramped audio rack. In these cases,

“PROTECT” flashes on the display and, when the temperature

inside the unit lowers, the sound is automatically muted and

the protective circuit is released. Readjust the volume level to

resume normal use. If the temperature does not sufficiently

lower within a certain amount of time after the protective circuit

trips, the OPERATE indicator on the display flashes a red color

and power shuts OFF.

• In the Event of Amplifier Trouble

A protective circuit trips and automatically shuts OFF the power

if abnormal voltage is detected in the power circuit for whatever

reason. The same happens if the main fuse inside the amplifier

blows. In these cases, the OPERATE indicator on the display

flashes a red color.
