Pikcup Input - QUAD 33 Instruction Booklet

instructions provided with the loudspeaker should be
followed. Each loudspeaker should be capable of hand-
ling the full output of the power amplifier.
Notez Quad electrostatic loudspeakers prior to serial
number 16800 need slight modification before
being used with the Quad 303 amplifier.

The pickup input is via a 5-pin plug and the same
connections are used for all types of pickup. The neces-
sary change in input circuitry to suit different types of
pickup is achieved by the Disc Adaptor Board. This
board provides matching for pickups of low output
magnetic types (Ml), high output magnetic types (M2),
ceramic types (Cl), and a spare position (Sl), according
to the edge inserted into the holder. (See Specification
on Page 20).
The M2 position should normally be used for most
magnetic pickups but for those with very low outputs
Ml should be used instead.
The fourth position is to enable the amateur or
professional engineer to provide any other circuit con-
flguration he may require and it also provides, of course,
facility for accommodating any new type of pickup
which may be introduced, requiring a different input
from existing types.
