Caring for the wood:
With proper care, the wooden enclosure will last a 
lifetime. To ensure it stays in perfect condition, do not 
place near any heat source or on top of any hot 
equipment. Avoid leaving in direct sunlight, or in 
excessively dry or humid environments for long periods 
of time.

DOMINO PHONO PREAMP

Powering on: When turning your system on and off, it’s 
important that the Domino be the first thing you switch 
on and the last thing you switch off. This gives the 
output time to stabilise and will avoid nasty pops and 
clicks coming through your speakers. It’s also a good 
idea to switch your system off as above before 
adjusting Domino’s gain settings.
Setup: It's best to use the lowest gain setting that 
provides you with enough volume. Lower gain settings 
have lower noise, higher overload margins and are 
more resistant to interference. If you're using an MM 
cartridge, start with 40 dB gain and increase if required. 
For MC, start with 49 dB.
Troubleshooting:
Distortion: If the sound is distorted on loud passages, 
the gain stages may be overloading. Lower the gain 
setting until the distortion disappears.
Low pitched hum: Make sure your turntable’s ground 
lead is connected to the Domino’s ground post. Try 
plugging turntable or amp into different sockets.
Interference: Make sure your turntable’s ground lead is 
connected to the Domino’s ground post. Use high 
quality shielded interconnects. Attach a ferrite core to  
the ground lead near Domino’s ground post.
