Quad 44 is provided with two identical Tape inputs, which provide
optimum matching for all commercially available open reel and
cassette recorders. The correct record level and replay sensitivities
are selected by the DIP switches on the Tape boards accessible
through the small access panel as the Disc switches. Recording can be
made on either or both machines at once and dubbing either way is
possible,simply by pressing the appropriate pushbuttons.The signal at
the record out socket is unaffected by either Volume or Tone and
Radio and Auxiliary inputs provide a flat response over the audio
band with an input sensitivity suitable for most radio tuners
Quad 44 has three outputs, low level using the standard 4 pin Din
socket to drive the Quad 405 or Quad 303 power amplifiers and
amplifiers with similar input sensitivities, medium level via phono
sockets to drive amplifiers with an input sensitivity of between
0.775 and 2 volts, and high level via phono sockets with a maximum
output of 5 volts.A.C. Input and Outputs
Quad 44 has a double insulated power supply and is suitable for
operation on 1 20v or 240v 50 or 60Hz. There are three switched A.C.
outlets to supply the power amplifier and ancillary equipment.
Volume control is of the detente type with a specially designed law
to give the user maximum control at normal listening levels, and
inter-channel balance is extremely accurate over the entire range of
the control. The volume control varies feedback over the amplifier
stage so that the noise and signal are attenuated together, and the
specified noise level is maintained at normal listening levels.
Balance control enables the listener to adjust the balance of output
level between the two channels, but can also be used in the 'Mono'
position to provide a monophonic output to both loudspeakers. With
the slide control central, the output is the sum of both inputs. As
the control is moved to the right, the sound from both loudspeakers
contains progressively more right input and less left input until
when the control is fully over, the output on both loudspeakers is
from the right channel input only. Movement to the left produces the
converse. As with all the old Quad equipment, the 44 is no exception
to the rule, it is built to last, with the fact that so many of these
units are still in use today is testament to that fact.
