comment: Performance aside (for the moment), little
design quirks mean a lot in terms of the feel" of a given
piece of stereo equipment; and the 2270 is one of those
units that, with a little use, takes on its own personality,
The silky and noise-free action of its pushbuttons, the
horizontal tuning wheel, and the clutched triple tone
controls (bass, midrange, and treble) with detents for
repeatable settings all contribute to this feeling of indi-
viduality.

Below the tuning meters, dial, and tuning wheel are
three groups of switch buttons with four buttons in each
group. The first has one button to convert the signal-
strength meter to read multipath, a high-blend switch,
and two buttons for tape-monitor switching. The second
has two for mono-mode switching (permitting selection
of left, right, or both signals) and two for filtering-high
and low. At the right are buttons for loudness compen-
sation, FM muting, m'ain speakers (on/oft), and remote
speakers (on/off). Across the bottom are six knobs: se-
lector, the three tone controls, balance, and volume. At
the extreme left are input and output jacks for an added
tape recorder. The output is in parallel with the two tape
outputs on the back panel; the input overrides those
from the back panel. At the extreme right are the power
on/off switch and headphone jack, which is live at all
times.

On the back panel are the main and remote speaker
connections, switched and unswitohed AC conven-
ience outlets (one each), a Quadradial output (for use
with an adapter should a quadraphonic broadcast
method be approved), connections for AM antenna and
75-ohm or 300-ohm FM leadin, a local/distant FM
switch, a screwdriver adjustment for FM-muting level, a
chassis ground connection, and the pairs of phono-iack
inputs and outputs. These include preamp-out and
main-in connections-for use with room equalizers for
example-that are delivered fitted with jumpers for nor-
