SPHINX Phono Equaliser
6
4. INSTALLATION AND CONNECTIONS
Installation
The Phono equaliser will not become very hot, so
placement is not critical, although you should not
place it on top of or near other heat-radiating
equipment (such as power amps) or in direct
sunlight.
If you use it in a closed cabinet or on a bookshelf,
please ensure unrestricted ventilation around the
component.
To prevent any possible interference keep power
supply cables away from all audio cables.
Note: The mains power transformer of the Phono
equaliser is mounted at the front side.
Position the Phono equaliser as close to the
turntable as possible while keeping the cables as
short as possible.
Always connect the separate ground wire from the
turntable to the GND terminal (6).
If all these conditions are met, the Phono equaliser
will perform to the extremely high standards it is
designed for.
Connecting the mains cable
Before you connect the cable please check
whether the mains voltage indicated on the
manufacturer’s label on the rear panel is the
same as your local mains voltage.
If not: please contact your dealer and do not connect
the component to the mains.
After you have switched the Phono equaliser on with
the 0./ 1 switch (9) it will always be active.
This way the electronic circuits will be kept at
optimum working temperature so you can enjoy
maximum audio quality immediately after switching
on. Additionally it significantly increases the life span
of the component.
Via the Control IN input (3) however it may be
remotely switched to Standby by another Sphinx
component.
Connect the mains cable after you have connected
all other components in the system, have double-
checked all connections and after the Phono
equaliser has been matched to the cartridge in use
(see Chapter 5).
Audio connections
Before you start connecting equipment it is always
wise to check whether all the mains power cables of
all components are disconnected from the mains
outlets! This will prevent any damage to the
loudspeakers and amplifiers caused by incorrect
wiring or settings.
Make sure you connect L and R properly. Most cinch
cables use Red for the Right channel and White or
Black for Left.
The cinch connectors on the rear panel of the Phono
equaliser have a red centre for the right channel and
a white one for the left channel.
When making the connections please refer to the
descriptions for parts 2. to 9. on page 5.
Connecting the pre-amp
Connect the R OUT and L OUT (6) to the LINE- or
AUX inputs of the pre-amp, using normal cinch cable
(but of top quality!).
Connect the separate ground wire (if supplied) from
the pre-amp to the GND terminal (4).
Connecting the turntable
Connect the (in most cases fixed) audio cable from
the turntable to the R IN and L IN (2).
Connect the separate ground wire from the turntable
to the GND terminal.
Connecting the optical cables
Connect the CONTROL OUT of a Sphinx pre-amp to
the CONTROL IN (3) of the Phono equaliser. It will
then switch to Standby mode as soon as the pre-
amp is set to Standby.
Connect the Phono equaliser’s CONTROL OUT (5)
to the CONTROL IN of another Sphinx component. It
will then automatically switch to Standby as soon as
the Phono equaliser is selected to Standby.
Ensure proper connection of the optical cables,
otherwise the Standby LED on the front panel may
remain off, even though the Standby mode is
activated.
If the CONTROL IN is not used and the Phono
equaliser is placed in strong direct sunlight, the
Standby mode may self-activate.
In that case you should place the supplied dummy
connector in the CONTROL IN jack.
