Specifications

Distortion on FM is less than 0.5 %. You get all there is
to hear with this FM tuner. The MPX section of the MAC
1500 uses six transistors and two tubes. In test after test
this particular MPX section outperformed all other de-
signs. One added advantage of the predominantly
solid state design of the multiplex section is the long
life expectancy of the circuit.
POWER. This is one thing you have plenty of with the
MAC 1500. The power output section of the MAC 1500
will drive even the most inefficient speaker systems.
Here is a dual power amplifier with 30 watts continuous
power per channel with both channels operating. Dis-
tortion is less than 0.5
% from 30 cycles to 20,000
cycles. Now you can listen to music with the knowledge
your power amplifier delivers all the power your
speakers need. Good full rich music is yours with the
MAC 1500.
superb. The reason is simple. Pride of craftsmanship.
In tuner design, one misplaced wire, one lead length
too long, one capacitor out of place, can affect the
performance of the tuner.
Each MAC 1500 must pass 171 tests before it is ready
for you. The tuner section uses six tubes and two tran-
sistors. Tubes as RF amplifiers still give maximum sensi-
tivity with greatest overload protection. It is virtually
impossible to overload the MAC 1500 with too much
signal from a nearby FM station. A transistor is used in
the oscillator because it is not susceptible to drift.

Despite the small space available for tuner placement
the MAC 1500 gives you a 2.5 microvolt FM stereo
tuner. This sensitive tuner brings you clear noise free
reception from distant stations. The tuner section is
your particular room. The prime function of a preampli-
fier is to reproduce records and tapes with full accuracy
and sonic realism. Records are made with the bass cut
and the highs boosted. This allows more musical infor-
mation to be put on the record groove. Tapes are also
recorded with the bass cut and the highs boosted. For
true musical enjoyment the MAC 1500 reintroduces the
bass and the highs following accurate and definite
standards. Your records and tapes will sound alive and
thrilling when you hear them through the MAC 1500.
The solid state preamplifier uses 12 silicon planar tran-
sistors. Silicon planar transistors are used because of
their high thermal stability, low noise and superior high
frequency response. The silicon planar transistors make
the fantastic sound reproduction possible.
