Operating Voltage and Mains Conditions
A good quality three pin, 13 ampere IEC standard, detachable mains lead is
provided for use with your power Amplifier. It is recommended that you use this
lead. Please contact us for advice if replacement is required.
The power supply is set at the factory to work at either 110 / 110 VAC or 220/240
VAC at 50/60Hz. Please use your amplifi er in regions that have the same voltage
conditions as those detailed on the back of your unit.
If you move to a country that uses a different mains voltage please consult your
distributor to arrange for your amplifi er to be adjusted accordingly.
Thus total audio performance is assured anywhere in the world.
Power Supply Topology
Our New 'Balanced Zero Ripple' power supply provides the amplifi er sections with
a rock steady Ppower supply rails, essential for deep articulate bass, as well as a
grain free treble performance. You will notice that even when pushed very hard the
Couplet 500M will not change is sonic presentation due to the huge demands on the
power supply.
This regulated characteristic is achieved without the use of feedback and is thus able
to react as quickly as the amplifi er demands, no lag, no compensation, just an almost
limitless reserve of power that would only normally be available on a power supply
around four times the size of that found in the Couplet 500M.
Great care is take to ensure that mains bourne noise (including DC components) do
not enter the amplifi er and thus compromise the amplifi er performance - this fi ltering
and in some cases blocking ensures that the Couplet 500M is essentially silent.
Regulation and fi ltration are only part of the picture - a power supply must also be
low noise, and not interfer with the other delicate parts of the circuit electrically or
magnetically. It will take you only a few moments to hear that we have created an
amplifi er that can deliver a deftness of touch combined with tremendous punch.
