TEAC AS-M30
Stereo
Integrated Amplifier
For years
Teac has been justifiably recognized as a world leader in tape recording and
playback equipment. Teac tape decks provide total performance, not only in
reliable, high stability tape transport mechanisms, but also in ultra low
distortion amplification circuitry.
This
advanced signal processing technology has been fully incorporated in our new
line of stereo integrated amplifiers. They offer great sound and versatility
with plenty of useful (not excess) power, and important, functional features –
not just fancy frills.
Teac amps
really give you your money's worth.
Designed for
high performance and smooth power, the AS-M30 is perfect for the audio
enthusist who knows and wants good sound. The kind ofmusic fan who doesn't feel
the need for one of today's astronomically – priced amplifiers with needlessly
high power output (and consumption).
The latest
technology has been combined with an all-new look at circuit configuration and
features, resulting in vastly improved reliability plus lower distortion over
the entire frequency and power range.
The AS-M30
is a trend-setting answer to what an integrated amplifier should be.
All-Stage
Direct-Coupled OCL Power Amplifier
The power
amplifier section includes a differential input stage, assuring minimum noise
and distortion throughout the entire power range, and an OCL (Output
Capacitor-Less) output stage for improved low frequency response and damping.
All stages are direct coupled, meaning that the signal path is free from
waveform-distorting coupling components. This assures accurate signal
transmission – from first stage to output.
Low Noise
Integrated Phono EQ Amplifier
A
differential first stage with current mirror circuitry achieves high
sensitivity and wide dynamic range with minimal distortion in the equalizer
amplifier. The usual problems with inferiors signal-to-noise ratio in low-level
preamplifier circuits have been solved by the use of PNP-type semiconductors in
the first stage. The result is smooth, undistorted phono reproduction with
nothing but total silence in the background.
For improved
reliability and long-term stability, the entire EQ amp section has been
incorporated in an integrated circuit.
Bipolar
Power Supply
Amplifier power supplies are often a source of crosstalk and
intermodulation distortion. The AS-M30 however, incorporates a bipolar power
supply with a massive transformer and large 4,700 μF capacitors to assure maximum stability
and minimum distortion even at the highest output levels. There's plenty of
power to spare for the most dynamically challenging passages.
Unique Tone
Control Configuration
The AS-M30
tone control circuitry is fully incorporated into the power amplifier negative
feedback loop, eliminating the usual additional stage of amplification. This
not only contributes to circuit economy, but also means extra low-distortion
tone control.
41-Position
Detent Volume Control
A large,
easy-to-handle volume control knob permits accurate setting of listening levels
with a minimum of fuss. Its 41 detent positions are ideal for reference level
location, and they make it easy to reset desired volume levels.
Connections
for Two Independent Tape Decks
Connect two
reel-to-reel and a cassette deck for maximum recording flexibility. A tape copy
switch is also provided; you can dub recordings from either deck to the other
by simply flipping a switch. This eliminates the time-consuming fuss of Having
to reconect tape deck leads every time you want to copy a tape.
Speaker
Selector Switch
This
important feature lets you use two sets of stereo speakers with convenient
switching from the front panel. You can select set A, set B or sets A and B
simultaneously. Set up all four speakers in one room for an „all-round” sound,
or place one set in another room for an expanded listening environment.
The speaker
selector switch also has an Off position which mutes both sets of speakers, but
keeps the headphone jack active – convenient for late-night listening via
headphons.
Loudness
Control
At low
listening levels, the sensitivity of the human ear to low high frequencies
decreases. Music tends to lack presence and sound „dull”.
To
compensate for this, the AS-M30 incorporates a loudness control which boosts
the lows and highs in accordance with the ear's frequency loss curve.
This means
that you hear all your music in the proper perspective even at low volume.
