PSX-R REGULATED POWER SUPPLY -
The PSX-R is a highly regulated DC power supply. Its use
will upgrade the sonic performance of your Cyrus aEQ7.
No adjustments are necessary when connecting the Cyrus
PSX-R to the Cyrus aEQ7 - full connection instructions
can be found on page 4.
RIAA or IEC?
In the early 1970s the playback characteristics of phono
reproducers were amended. Many audiophiles feel that this
new IEC curve with its steeper bass roll-off results in a
poorer bass response than the original RIAA curve. The
Cyrus aEQ7 offers you the choice of both.
If your turntable is prone to feedback or rumble and/or
your loudspeakers have a highly extended bass response,
you may occasionally experience some disturbance in the
deep bass when using RIAA as against IEC correction.
INTERCONNECTS
Quality interconnects are essential for good fidelity and
effective screening against hum and noise. Many low cost
interconnects are unscreened or offer minimal screening.
If you need a tone-arm interconnect ask for a quality low-
capacitance fully screened lead. It will be worth the
investment.
Never extend tone-arm leads. Doing so can cause poor
H.F. response, hum and noise.
TURNTABLE AND AMPLIFIER GROUNDING
The grounding of modern cartridges and tone-arms is
straight-forward and installation should be trouble free.
Some older units use a cartridge ground lead to carry the
turntable and tone-arm ground which is why you may not
see a ground return connection from the turntable.
Although not in accord with best modern practice, this
method is acceptable.
Some cartridges have a link connecting one of the negative
signal pins to the metal cartridge shield. With certain tone-
arms this link could make connection between the tone-
arm metal work and the cartridge ground return and set up
a hum loop through the Cyrus aEQ7. If you think this is
the case with your turntable, ask your dealer’s help before
you remove this tag.
If you are using the Cyrus aEQ7 with equipment that
requires a mains earth, do not use the MM or MC ground
terminals for this purpose. Use an appropriate ground
terminal on the ancillary equipment.
HUM AND NOISE
Take care to place your Cyrus aEQ7 and turntable as far as
possible from amplifiers, TV sets and appliances.
As well as turntables, the Cyrus aEQ7 benefits from
placement away from loudspeakers and other sources of
mechanical disturbance.
