CONNECTING POWER TO THE UNIT

Refer to figure 1, rear panel drawing above.

Plug the moulded IEC connector of the supplied mains
lead into the power inlet on the rear of the unit.

The mains fuse is located on the rear panel. It must only be
replaced with the following types:

U.K. / Europe - 230V

T100mA/20mm

N. America / Far East - 115V

T200mA/20mm

In the U.K., the Cyrus aEQ7 power lead is supplied fitted
with a mains plug. If the plug fuse should need replacing
ensure that it is replaced only with a 3 Amp Fuse.

CONNECTING A CYRUS PSX-R

If a Cyrus PSX-R is to be used with the Cyrus aEQ7,
connect the umbilical cord of the PSX-R to the 5-pin
Cannon input socket of the Cyrus aEQ7. When correctly
fitted the connector will latch into place in the socket.
No other connections or internal modifications to the
Cyrus aEQ7 are needed for PSX-R connection.
Note:  Please ensure that the Cyrus aEQ7 and the PSX-R
are unplugged from the mains before connecting the units.
When a PSX-R is in use, both the Cyrus PSX-R power
supply and the Cyrus aEQ7 will require mains power. For
more details refer to the Cyrus PSX-R Instruction Manual.
