Audio Note M8 Phonosig - Manual (Page 5)

Note interconnects are recommended, as they are manufactured to the same exacting
standards as all of our products.
Operation
Once all the connections are completed and checked, make sure all power amplifiers are off and flip
the mains rocker switch located on the back panel of the pre-amplifier to the 'on' position.
The M8 Phono Signature is a vacuum tube design and therefore requires about 45 seconds warm-up
time. After this the remaining system components may now be turned on.
Bedding-in time
The pre-amplifier requires around 200 hours of initial use (called 'bedding-in time') before the circuitry
becomes stable and optimum performance is realised. As the pre-amplifier beds in, the sound will
become more lucid, detailed and expansive.
After the initial bedding-in, a short warm-up period is required each time the unit is turned on before
optimum sonic performance is reached.
The M8 Phono Signature is designed for continuous operation and may remain switched on, even when
not in use. You may, however, prefer to turn the unit off between uses by using the power switch located
on the back panel, next to the mains inlet socket.
NOTE: Always turn the pre-amplifier(s) on before turning on the power amplifier and always turn the
power amplifier off before turning off the pre-amplifier. This will prevent any buzzing or popping
sounds from occurring.
After-care
Cleaning
Cleaning the M8 Phono Signature is best done with a soft brush - some photographic stores are able to
provide suitable brushes. Alternatively, a soft cotton cloth may be used with a mild propriety cleaner for
removing dirt build-up. Strong or alcohol based solvents may damage the finish of this amplifier. Ensure
the pre-amplifieris switched off and cold when cleaning. Do not wet the unit.
Replacing the vacuum tubes
The vacuum tubes in the M8 Phono Signature are carefully selected from Audio Note's vast stock to
provide optimum performance and reliability. Should these tubes require replacement, please contact
your Audio Note dealer, who will be able to supply the correct parts.
