The AM2
was designed to compliment the Control 22
and FM1 units. The earlier AM1
(distinguishable by it's "half-moon"
style switches) was very rapidly superseded
by the AM2 as the complimentary
am tuner for the set. Today, AM1's
are extremely rare, and can attract large
price tags. |
The tuner boasts LW, MW,
and SW reception, and works well over all
three wave-bands. The tuning control
knob exhibits another Quad innovation in that
it incorporates a small gear system which
allows fine tuning if the control is only
turned a little, and much more
rapid movement over the frequencies if turned quickly. |

The AM2 was designed to
cater for two receiving requirements - the
ability to receive strong local signals, but
also have sufficient sensitivity to receive
stations from much further afield. The frequency
response switch facilitates this - in the "wide"
position the response is optimised for local broadcasts,
in the "filter" position high
frequency whistles associated with leaking
carrier waves are eliminated, and in
the "narrow"
position, very accurate tuning of weaker distant
signals is possible. In this "narrow"
position, the tuning indicator becomes operational
also... |
...the "magic-eye"
style tuning indicator is used to aid very
accurate tuning. Once almost tuned
to a station, you can attain optimum signal response
by tuning until the shaded area in the centre
of the blue display is at a minimum.
The Quad AM2 manual also suggests utilising
the 5K equalisation slope on the Control
22 pre to further improve sound quality from distant
stations. |

Just like the FM1, the AM2
is powered from the Control
unit via a four pin plug. It also has
a mono RCA/phono output and two
4mm sockets - one for an earth connection,
the other for the aeriel. Pictured opposite
is the full 22/FM/AM/II set-up. It's not
advisable to always run the units stacked
as shown in the photo due to obscuring the ventilation
ducts on the bottom and top
of the units, but it's fine for short periods
of usage.
