X-CANV8P
INTRODUCTION
Congratulations on the purchase of the new X-CAN V8P
integrated valve headphone amp. Great attention has been paid
to internal layout, isolating each circuit section to prevent
possible interaction.
The unit features our highly refined ECC88 dual triode valve
input amplifier circuit coupled with a new low output
impedance driver stage to improve current delivery and
dynamics to lower impedance headphones. Twin jack sockets
are provided so it is possible to share the musical experience!
A USB input is also provided for listening to computer-based
music collections. This interfaces easily with most PC/MAC
computers without additional drivers.
The X-CAN V8P may also be used as a high quality valve
preamplifier by connecting the pre-outputs to separate power
amplifiers’ line input. In a pre-power setup, the TAPE out
from the preamp can be connected to the X-CAN V8P input
(loop outputs are also available on the rear of the X-CAN V8P
for recording etc). The pre-outputs from the X-CAN V8P can
then be directly connected to the power amplifier inputs. The
volume control on the X-CANV8P will then control the
volume with the preamp controlling the source input. This
creates a two-box valve buffered preamp system.
The resultant performance achieved by this unit is among the
best in the world. It has excellent signal to noise ratio, low
distortion, wide bandwidth, huge dynamic range,
extraordinary resolution and fine detail.
INSTALLATION
POWER CONNECTIONS
The X-CAN V8P requires a free mains socket for its power
supply. The power supply then connects using its flying lead
to the DIN 24V AC socket at the back of the unit. We advise
that you use only the supplied X-series adaptor for this unit,
or a Musical Fidelity power supply.
AUDIO CONNECTIONS
Inputs: Connect analogue input to RCA line inputs
(see p.7 For more information). Use good quality fully
connected (signal and ground) coaxial phono cables for all
signal connections.
Outputs: Connect one or two sets of headphones to the
output sockets
The LINE outputs allow direct pass-through of the input
signals to tape/MD/CD recorder, for example. They are
directly connected to the line inputs and are not affected by
the volume control on the X-CAN V8P
The PRE-outputs allow direct connection and control of a
power amplifier They are connected to the headphone outputs
and are controlled by the volume control on the X-CAN V8P.
CLEANING
Before cleaning the unit, switch off power at the mains switch
and remove the mains plug from the wall socket.
Clean the cabinet and remote control unit using a moist cloth.
Using solvents, white spirit or thinners is not advised, as they
could damage the surface finish.
INSTALLATION
Position the X-CAN V8P on a stable, horizontal surface
where there is no risk of it being knocked, or subjected to
vibration such as from loudspeakers.
The X-CAN V8P must be protected from humidity - if the
unit is moved from a cold place to a warm room, leave the unit
for an hour or so to allow sufficient time for the moisture to
evaporate.

AMPLIFIER OPERATION
STARTING
Once all connections are made, the power LED on the
front panel will light, indicating unit is ready for use.
VOLUME
The volume control knob should be adjusted for a
comfortable listening level.
LINE IN
To use the line input connect desired source to line in
RCA sockets. To listen to music from the line input,
move the front panel switch to the down position.
USB INPUT
To use the USB input connect computer to USB input
socket. To listen to music from the USB input, move
the front panel switch to the up position
LINE OUT
The line output RCA sockets are included to facilitate
connection of the X-CAN V8P into an existing system.
To take advantage of this, the X-CAN V8P can be
connected to the tape output (or similar) of any pre- or
integrated amplifier. Any device that was plugged into
the tape output should now be plugged into the line
output RCA sockets on the X-CAN V8P which will
reinstate the original connection, the X-CAN V8P
passing on the signal for recording or other purposes.
These outputs are not affected by the X-CAN V8P
volume control.
PRE-OUT
The pre-output RCA sockets are included to facilitate
connection of the X-CAN V8P into a power amplifier.
To take advantage of this, the X-CAN V8P can be
connected to the tape output (or similar) of any pre- or
integrated amplifier (any device that was plugged into
the tape output should now be plugged into the line
output RCA sockets). The pre-outputs from the X-CAN
V8P can then be directly connected to the power
amplifier inputs. The volume control on the X-CANV8P
will then control the volume with the preamp controlling
the source input.
HEADPHONES
Up to two pairs of headphones can be connected to the
unit through the front panel jack sockets.
Both sets will then be simultaneously controlled by the
volume control.
Note: Two different headphones thus connected may
produce differing output levels and/or musical tones.
This is normal and due to design of the respective
headphones.

AMPLIFIER OPERATION
Computer setup for input USB input
PC users
A good quality USB A to B cable is required to connect
the unit to the computer (not supplied).
Plug the B (square) end into the socket in the back of
the X-CAN V8P
Plug the A (rectangle) end into a free USB socket on
the computer.
The computer should detect the new hardware and
install a generic driver automatically (No setup or driver
disk required).
CD, MP3, WAV files played on any software should
now play through the X-CAN V8P. This device has
been designed to work with PC Windows 98, ME, 2000,
XP as well as Apple Macintosh OS X.
Please note:
This device is a high speed serial data processor, and by
its nature, requires a very high volume of USB
bandwidth. It will benefit greatly from being the only
device connected on its USB ‘bus’. Sharing the same
bus with other devices may cause unwanted artefacts
such as dropouts or temporary loss of signal. This
especially includes the use of the X-CAN V8P on a USB
hub/splitter alongside other USB components
Check the computer has picked up the device and is
currently using it by clicking: (most Windows versions)
- Start
- Settings
- Control panel
- Sounds and Multimedia
- Audio

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
Check audio input lead connections
Sound is not precise, lacking in bass and
stereo image
Headphone(s) connector plug not fully
pushed in
Lead fault in headphones
Check plug is inserted fully and securely
Check phones on Headphone output of a
different unit
Hum
Audio connector plug not fully pushed in
Cable Fault
Unsuitable Cable
(e.g. cable grounds not connected)
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 analogue AND digital,
please use good quality screened coax;
signal and screen directly connected both
ends.
No audio output, or too low level output
Incorrect or missing connections
USB Driver not selected (PC or MAC)
Check connections and make sure they
are secure.
See P.9 PC users or MAC users section
No audio output from USB input
USB Cable not connected
USB Driver not selected (PC or MAC)
Check connections and make sure they
are secure.
See P.9 PC users or Mac users section
Not detected when connected to USB
USB Cable faulty
USB not working/enabled on computer
Correct USB drivers not installed
(can happen particularly with factorypreinstalled Windows operating systems)
Check and replace cable
Check USB port functions with another
device.
Please check with the computer
manufacturer. Enquire about USB driver
or update.
Dropouts in sound (USB input)
Shared USB port with another device
Computer busy with another application
Computer low on resources
Avoid sharing the USB port with other
devices, if possible.
At times an application (program) may
intervene, sometimes invisibly e.g. a
virus scanner. When this happens,
computer resources are temporarily used
up, and playback may suffer. This is not a
fault. Try running fewer applications if
possible.
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-CAN V8P, as this will invalidate the guarantee.
