FEATURES

WIDE DYNAMIC RANGE

The 80-700 is a 3-stage amplifier with negative
feedback; this assures correct equalization or com»
pliance to the RIAA Standard, and effectively reduces
clipping. The result is more natural sound at any
volume level.

HEADSET CONVENIENCE

The SC-700 may be monitored with a headset, to check
the condition of the system and the tonal quality while
making recordings. And a headset, of course, lets
you listen in private when this is more convenient.
The SC-700 incorporates an individual circuit designed
especially for use with a headset for noticeably higher
fidelity.

IMPROVED TONE CONTROL SYSTEM

There are numbered "step controls for both bass and

treble. Their ranges have been determined by Pioneer's
long acquaintance with the musical tastes of high
fidelity enthusiasts.

MUTING SWITCH

A simple touch of this button instantly lowers the
level of sound by at least a half turn of the volume
control-handy when the phone suddenly rings, for
example.

EASY CARTRIDGE COMPARISON

The two inputs for magnetic cartridge operation allow
you to compare and evaluate the tonal quality of
different cartridges.

SIMPLIFIED OPERATION

The SC-7OO has been carefully designed for stable
operation and ease in use.

INSTALLATION

ing points.

STEREO SYSTEM SETUP USING
SC-700

The 50-700 is a stereo control amplifier which selects
a desired program source among those connected to
the SC-700 and provides it to the stereo reproduction
system. Typical system setups using the 80700 are
illustrated in Figs. 3, 4 and 5 as shown in these
figures, the 80700 unit may be combined with
separately purchased stereo power (basic) amplifier,
turntable, tape deck, etc. When combined with the
PlONEER lS-70 or IS-80 integrated speaker system,
the SC-700 unit can be directly connected to the
DIS-70 or -80 system.
