Audio Note M5 RIAA - Manual (Page 11)

OPERATION
Once all the connections are completed and checked, ensure that the volume control
on the following preamplifier or integrated amplifier is at the minimum setting (rotated
all the way left).
Ensure that power supply for the turntable connected to the M5 RIAA phono
stage is switched ON. Source components should always be the FIRST
components to be switched on and the LAST components to be switched off.
Ensure that all pre and power amplifiers connected to the M5 RIAA phono
stage are switched OFF. Any power amplifiers in use should be the LAST
components to be switched on, and the FIRST components to be switched off.
The above procedure minimizes the possibility of loud noises produced by
components at switch on being passed to the loudspeakers and possibly causing
damage.
Turn on the M5 RIAA phono stage by using the rocker switch located on the rear
panel, above the mains inlet IEC socket.
Turn on your pre amplifier / power amplifier / integrated amplifier. If you are using a
pre / power combination, always turn on the pre amplifier BEFORE the power
amplifier(s).
The M5 RIAA phono stage is now ready for operation!
Bedding in
The M5 RIAA phono stage requires around 100 hours of initial
use (called “bedding in”) before the circuitry becomes stable
and optimum performance is realized. As the device “beds in”
the sound will become increasingly more smooth, detailed and
open. A warm up time of approximately 30 minutes is required
each time the device is switched on before optimum sonic
performance is reached.
Cleaning
No special maintenance is required for the M5 RIAA phono
stage. Use a soft, clean lint free cloth to remove any surface
marks from the casework. For finger marks / grease, use a soft,
clean lint free cloth, lightly moistened with a solution of warm
water and mild detergent. Do not use any alcohol or solvent
based cleaning products, as they may damage the finish.
ENSURE THAT THE DEVICE IS SWITCHED OFF AND
DISCONNECTED
FROM THE MAINS ELECTRICITY
SUPPLY BEFORE UNDERTAKING ANY CLEANING.
Valve Life
The valves supplied with your M5 RIAA phono stage should
provide approximately 4 years of operation. They are specially
selected by us, and should only be replaced with valves of the
same type and specification. Please consult your Audio Note
(UK) dealer should your valves need replacing. Alternatively,
feel free to contact us directly.
