Appendix

Problem

There is a lack of bass

and no ambience.

A "humming" noise is

heard.

Playback audio from the

component connected

to the BAL input jacks

sounds distorted.

Bass lacks depth when

BAL is selected.

Playback audio is

distorted while you

listen to a connected CD

player or tape deck

through headphones

(that are connected to a

CD player or tape deck).

The volume level of the

vinyl record is too low.

The remote control

does not work or

function properly.

Maintenance

Mirror-finish side panels

We recommend that you use a cleaning cloth such as those made for pianos.

Other surfaces

Do not use chemical agents, such as benzene or thinner for cleaning. Otherwise, the surfaces might be damaged.

Wipe the surfaces using a soft dry cloth.

Cause

The + and − wires are connected in

reverse at the amplifier or the

speakers.

Incorrect input or output cable

connections.

The turntable is not grounded to the

GND terminal.

The level of the signal at the balanced

input jacks is exceeding the allowable

input level.

The polarity is incorrect.

The power to the unit is turned off.

The PHONO switch on the front panel

is set incorrectly.

The remote control has been used

out of the operating range.

Direct sunlight or lighting (from an

inverter type of fluorescent lamp,

strobe light, etc.) is hitting the remote

control sensor on the front panel.

The batteries are weak.

Remedy

Connect the speaker wires to the correct + and −

phase.

Connect the cables properly. If the problem

persists, the cables might be defective.

Connect the turntable to the GND terminal of this

unit.

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).

Select the correct polarity using the PHASE

selector.

Turn on the power to the unit.

Set the PHONO switch to the MM or MC position

according to the type of magnetic cartridge of the

turntable.

The remote control must be used within a

maximum distance of 6 m and no more than

30 degrees off-axis from the remote control sensor

on the front panel.

Change the orientation of the lighting or reposition

the unit.

Replace all batteries.
