Thank you for choosing our product!
Your Heed QUASAR is a first-class MM/MC phono stage with outboard power supply
which gives you the optimum connection between your cartridge and one of the line
level inputs of your pre- or integrated amplifier and thereby allows you to enjoy your
LPs to the highest fidelity possible in analogue reproduction. We sincerely hope that
you will agree, and that your QUASAR will provide you with many years of impeccable,
trouble-free operation.
Happy listening!
The QUASAR is designed to offer the finest performance available by avoiding
compromise, wherever possible. This detailed guide contains advice specifically
concerned with using this phono preamplifier, as well as more general warnings
about the use of domestic audio components.
Please read it carefully.
Precautions
Instructions — All safety and operating instructions should be read and adhered to exactly as written here or
as depicted on the unit. Please retain for future reference.
Water and Moisture — The unit should not be used near water — that is, near a bathtub, washbowl, kitchen
sink, laundry tub, in a wet basement, or swimming pool, etc.
Heat — The unit should be situated away from heat sources such as radiators, stoves, etc..
Power Sources — The unit should be connected to a power supply only of the type described in the operating
instructions or as marked on the unit.
Power-Cord Protection — Power-supply cords should be routed so that they are not likely to be walked on
or pinched by items placed upon or against them, paying particular attention to cords at plugs, convenience recepta-
cles, and the point where they exit from the unit.
Lightning — For added protection during a lightning storm, or when left unattended and unused for long periods
of time, unplug the unit from the wall outlet. This will prevent damage to the product due to lightning and power-line
surges.
Object and Liquid Entry — Care should be taken so that objects do not fall into and liquids are not spilled into
the inside of the unit. For this reason, no objects filled with liquid, such as vases or drinking glasses should be placed on
the equipment.
Damage Requiring Service — The unit should be serviced by qualified service personnel when:
— The power-supply cord or the plug has been damaged;
— Objects have fallen, or liquid has been spilled into the unit; or the unit has been exposed to rain respectively;
— The unit does not appear to operate normally or exhibits a change in performance;
— The unit has been dropped, or the cabinet damaged.
The QUASAR phono preamplifier and its outboard power supply do not have any user serviceable parts. It is
essential that repairs and updates are only carried out by our authorised trade partners — distributors and dealers — ,
or at the factory by Heed Audio itself. Many components are custom made, tested or matched and appropriate
I
replacements are often unobtainable from other sources.
Therefore, users should not attempt to service the units beyond those means described
in the operating instructions, or under any circumstances allow anyone to modify them.
Unauthorised repairs or modifications will invalidate the guarantee of the units.
Grounding or Polarization — Precautions should be taken so that the grounding or polarization is not defeated.
Radio interference — All Heed components are designed to provide reasonable protection against harmful inter-
ference in a domestic installation. However, there is no guarantee that interference will not occur in a particular
installation. If your Quasar does cause harmful interference to radio or television reception, which can be determined
by turning off and on, you are encouraged to try to correct the interference by one or more of the following measures:
— Reorient or relocate the receiving antenna;
— the separation between amplifier and receiver (radio tuner, television set, etc.);
— Connect the equipment into a power outlet on a circuit different from that to which the receiver is connected;
— your Heed dealer or an experienced radio/TV technician for help.
I
Maintenance / Cleaning — It is recommended to dust the equipment from time to time with a soft dry cloth.
Do not use cleaning solvents or abrasives for cleaning!
Always switch off and unplug the unit from the power supply when cleaning!
