Page 8 of

Basic problem-solving with an amplifier is similar to troubleshooting other electrical or electronic equipment. Always
check the most obvious possible causes first, such as the following examples:

Problem Probable

Cause Remedy

No power

Mains power supply is not fully
inserted into mains socket

Mains power supply lead is not fully
inserted into rear socket

Plug in securely

No sound

Wrong connections between input
sources and the unit

Cartridge incorrectly wired

Check audio input lead connections

Check cartridge wiring

Sound is not precise, lacking in bass
and stereo image

Cartridge incorrectly wired

Input connector plugs not fully
pushed in

Output connector plugs not fully
pushed in

Double-check cartridge wiring using
cartridge and turntable
manuals/wiring diagrams.

Check plugs are inserted fully and
securely

Hum

Turntable not earthed and needs
earthing

Turntable already earthed and makes
hum loop in system

Audio connector plug not fully
pushed in

Cable Fault

Unsuitable Cable

(e.g. cable grounds not connected)

Check turntable earthing lead is
connected to earthing post on XLPS
V8

Disconnect Earthing lead from
earthing post

Insert plug securely

Check cable is connected at both
ends.

N.B. some esoteric cables have
internal wiring intentionally
disconnected/modified. For best
results on all inputs AND outputs,
please use good quality screened
coax; fully connected signal-to signal,
screen-to-screen.

Plop Heard in speakers when
switching on or off or changing
MM/MC switch

High gain of XLPS V8 amplifying
circuit transients.

Not a fault.

Please ensure volume level on
amplifier is turned down if switching
the XLPS V8 on or off or changing
cartridge type switch whilst
connected.

If none of these actions affect a cure, please contact the dealer, or an authorised Musical Fidelity service agent.
Remember; never open the case of the X-LPS V8, as this will invalidate the guarantee.
