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.8  

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.8  

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 factory- 
preinstalled 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.  

Never open the case of the X-CAN V8P, as this will invalidate the guarantee.
