Quadraphonic stereo is the ultimate in sound realism, and
with Pioneers Model QC-SOO, a quadraphonic power amp
(or two stereo amplifiers) and four speakers you can enjoy
this sound brilliance today in your own home. This well-
made,high|y-advanced unit is unusually versatile, it provides
a choice of two totally different four-channel effects, which
are created from any existing two-channel stereo source
(tape, disc or FM), as well as discrete four-channel stereo,
the most genuine and thrilling four-channel sound. And it
can also be used as a conventional two-channel stereo pre-
amplifier if you intend to wait until adding another pair of
speakers to your existing stereo set. The Q0800 is a perfect
match for Pioneer/s Quadraphonic Power Amplifier (Model
QM-BOO). And its your most versatile introduction to the
grandeur of four-channel stereo, a solid investment it the
sound of the future that Pioneer has perfected today.

YOUR OWN ACOUSTICAL FIELD

The exclusive Pioneer Quadralizer contained within the QC-800
creates an all-encompassing four-channel sound field in your
home, giving you the same, full, life-like sansation of being in
an acoustically perfect concert hall.

CHOOSE YOUR FOUR-CHANNEL SYSTEM

The Quadralizer creates four-channel sound from any existing
two-channel stereo source-either tape, discs or FM. And the
Q0800 gives you a choice of three totally different four-channel
effects.

DISCRETE FOUR»CHANNEL STEREO

This is both the most authentic in terms of sound quality, and
the most expensive since it requires a fourrchannel tape deck
and special four»channel tapes. The sound is reproduced at a
very high degree of fidelity, since the tape deck reproduces
sound recorded on each of four separate tracks.

MATRIX-TYPE FOUR-CHANNEL STEREO

The matrix system of four-channel sound is one of the quad-
ralizing effect systems in the Q0300. This system creates a
room-enveloping sound field, when signals from a two-channel
program source are fed through a unique matrix circuitry con-
tained within the preamplifier. These signals are analyzed and
divided into four different signals which are then fed to four
loudspeaker systems for sound reproduction The matrix system
is highly suitable for the reproduction of popular music or small
combo group performances.

PHASE SHIFT FOUR-CANNEL STEREO

The phase shift system of four-channel sound is another of
the quadralizing effect systems in the QC-BOO. With this system,
the conventional left and right stereophonic channels are re-
produced from the two loundspeaker systems situated in front
of the listener. But added to this sound is a phase-shifted wall
of sound/, or concert hall effect which emanates from the pair
of loudspeakers placed behind the listenr. The result is the rich
depth of a live performance, a slight enveloping echo effect

through the two rear speakers, a thrilling musical experience.
The Pioneer phase shift system is especially effective in the re-
production of classical or operatic music.

HIGH STABILITY HEAD AMPLIFIER

The head amplifier section of the QC-800 incorporates a 3-stage
direct-coupling negative feedback circuit utilizing low~noise
silicon transistors and emitter-to-emitter feedback. These fea-
tures result in accurate equalizing characteristics with a wide
dynamic range and stable performance.

SWITCH-TYPE TONE CONTROLS

The tone control amplifier is a directly coupled three-stage
desing with a low-noise FET in its first stage. Its high, stable
input impedance assures precise tone control at any setting
without affecting the head amplifier. The tone controls are true
switch types which regulate negative feedback. Each switching
step has an effect of i3dB. Additionally, separate controls are
provided for front and rear channels, permitting total control
over the total tonal quality.

VERSATILE INPUTS AND AUXILIARY CONTROLS

inputs of the (QC-800 accept two turntables, two tape decks,
a tuner and a choice of two other sound sources. There are
separate headphone jacks for monitoring both front and rear
channels. Controls include an output on/off switch, a -20dB
muting switch, high and low filters and a tape monitor switch.
Versatility of the unit is practically unlimited.

CHANNEL LEVEL CONTROLS

Each of the four channels is equipped with a level control,which
permits total control over the sound field intensity even when
different speaker types are used for front and rear listening

TAPE-TO-TAPE DUFLICATING

Because the Q0800 has a pair of tape deck inputs, tape-to-tape
duplicating may be accomplished with ease. Normal two-
channel tape-to-tape duplicating is also possible, as if four-
channel tape-to-tape duplicating.
