The mains voltage selector switch provides simple, external adjust-
ment for operation on all international AC power standards.
At each switch position there is an acceptable tolerance over which
the performance of the unit will not be affected and this is 90v-130v
for the 120V position, and 180V-260V for the 240V position. If you
subject the unit to voltages in excess of this, you are likely to cause
damage. If the mains voltage is below those specified, there will be
reduced performance before the unit finally fails to work.
The green/yellow wire of mains cord
must always
be connected to the
electrical installations Safety Earth or Ground.
It is essential for personal
safety
, as well as proper operation of the unit, and is internally
connected to all exposed metal surfaces. Any rack framework that this
unit might be mounted into is assumed to be connected to the same
grounding circuit. the MSR-604 II has electronically balanced audio
connections and does not need disconnection of any safety earth for the
avoidance of hum loops.
The incoming mains power is fused within the MSR-602 II by the fuse
holder mounted on the rear panel. If it needs to be replaced it must be
properly rated as: 20mm T2AL250V for 240V voltage setting or T3.15AL250V
for 120V voltage setting. It is most important for continued safety that this
specification is strictly adhered to, and you will have found that spare
fuses of this rating are supplied together with your unit and manual.
It is very unlikely that this fuse will fail during normal use, and must be
treated with some caution as to the cause, if it should do so. One of
the most likely reasons will be because the mains voltage switch on
the rear panel is incorrectly set. Another reason can be the inadvert-
