Cyrus aEQ7 OPERATION
5 English
GROUND CONNECTIONS
Before connecting any input ensure that the turntable
motor and tone arm are securely grounded to the Cyrus
aEQ7.
There are two grounding systems in common use:
•
The motor and tone-arm grounds are internally
connected with a common ground wire. Connect this wire
to either the MM or MC ground terminal
j
or
1)
,
depending on the type of cartridge used.
•
There are two ground wires, one from the motor and
one from the tone-arm. Connect both these wires to the
appropriate ground terminal on the Cyrus aEQ7.
Note: There are other grounding systems – refer to
Additional Information on Page 9 for further details.
CONNECTING SOURCE INPUTS
The Cyrus aEQ7 accepts Moving Coil and Moving
Magnet cartridge inputs. If you have one turntable
equipped with a MM and another one with an MC
cartridge, both can be connected at the same time.
The Cyrus aEQ7 is supplied with a pair of special shorting
phono plugs. When using only one input, place a shorting
plug into the left and right inputs of the unused inputs.
Note: These shorting plugs must only be used as
described above. They should not be confused with regular
phono plugs.
MOVING MAGNET (MM) INPUT
The MM input
d
accepts the following cartridges:
•
Regular moving magnet cartridges
•
High output moving coil cartridges
•
Low output moving coil cartridges connected via step-
up devices
The MM input requires no special loading provisions.
MOVING COIL (MC) INPUT
The MC Input
c
is designed exclusively for use with low-
output moving coil cartridges without step-up devices.
Load matching – MC cartridges
Some MC cartridges are load sensitive and some may also
require an external capacitance load.
Your Cyrus aEQ7 is provided with a loading switch
b
so
that you can set up your MC cartridge for optimal
response.
Three load settings are available, 10
Ω
, 100
Ω
and 1K
Ω
.
Each load setting is available with or without a 1nF shunt
capacitor. These shunt settings occupy the last three
positions on the switch. Unless your cartridge instructions
advise otherwise, do not use any capacitance loading.
Unless your cartridge instructions recommend otherwise,
we suggest you use the 1K
Ω
setting.
