Problem Cause Remedy
See

A “humming” noise is
heard.
Incorrect input or output cable
connections.
Connect the cables properly. If the
problem persists, the cables might be
defective.
20
The turntable is not grounded to
the GND terminal.
Connect the turntable to the GND
terminal of this unit.
22
Both balanced and line cables
are being used simultaneously
between two components.
Do not use both balanced and line
cables simultaneously between two
components. Doing so would create
a ground loop that could generate
static and noise.

Playback audio from the
component connected
to the BAL 1 or BAL 2
balanced input jacks
sounds distorted.
The level of the signal at
the balanced input jacks is
exceeding the allowable input
level.
If the level of the signal at the XLR-
type balanced output jacks on the
connected playback component
is doubled compared to the RCA
unbalanced jacks, set the ATTENUATOR
selector located below the input jacks
to ATT. (−6 dB).

Bass lacks depth when
BAL 1 or BAL 2 (balanced
input) is selected.
The polarity is incorrect.
Select the correct polarity using the
PHASE selector.

vinyl record is too low.
The PHONO switch on the front
panel is set incorrectly.
Set the PHONO switch to the MM or
MC position according to the type of
magnetic cartridge of the turntable.
29
The remote control does
not work or function
properly.
The remote control has been
used out of the operating range.
The remote control must be used
within a maximum distance of 6 m
(20 ft) and no more than 30 degrees
off-axis from the remote control
sensor on the front panel.
18
Direct sunlight or lighting (from
an inverter type of fluorescent
lamp, strobe light, etc.) is hitting
the remote control sensor on
the front panel.
Change the orientation of the lighting
or reposition the unit.
