GENERAL INFORMATION

The Recordio Model R-802 is a dual track monaural tape recorder and player, and in

addition, will play two-track or four-track prerecorded stereophonic tapes.

The R-802 isequippedwith a quarter-track head, a 3-watt amplifj.er into which a stereo-

phonic preamplifier is incorporated, and two 4-inch speakers.

No additional amplilication is necessary when using the stereophonie preamplifier to

operate an external amplifier. The Model SA-801, also covered in this manual, contains

speakers and a power amplifier that matches the R-802 tape recorder amplilier. The SA-80I

is designed specifically for use with the R-802 for stereophonic playback.

This Recordio features pushbutton control for each tape transport mode. These modes

are: Rewind, Record, Stop, Play, andFastForward.

Double-track recording is used, giving two full-length recordings on a reel of tape. Any

size reel up to ? inches can be used.

A neon record Ievel indicator simplilies the record level setting. New recordings can

be made on previously recorded tape since the erase head is automatically positioned when the

RECORD button is pressed. Monaural recordings can be made from a radio, television re-

ceiver, or phonograph, in addition to those made directly from the microphone.

This recorder has twotape speeds, 7.50-inches per second, and 3. ?5-inches per second

Using both tracks of the tape, the recording times are as follows:

Stop button is depressed.

When the Forward or Reverse buttons are de-

pressed, the Record and Play buttons are locked so

they cannot be pressed down, with the possibility of

on the take-up pan (right). Again make certain

the reel slots catch the protrusions of the pan.

3. Release theStop button bypressing lightly onany

one of the other buttons so that all buttons are

in the release position. This releases the tape

brakes, simplifying tape threading.

4. Unwind about l4-inches of tape from the supply

reel. HoId a section of tape straight with both

hands and insert tape in tape slot making sure

the dull coated side faces rear oi machine.

5. Insert the free end of the tape into one of the

slots in the hub of the empty reel and turn it a

few turns to secure the tape to the reel.

tions or by joining selections into another se-

quence. Announcements may be insertedbetween

selections, etc. Unused sections can be spliced

togetler for re-use.

2. For best results, cut the tape at a slight diag-

onal, join ends together with splicing tape on

theglossy side andtrim off anyexcessive width.

To Play Quarter-Track Stereophonic Tape

1. Thread the tape.

2. Connect the Stereo output jack to the input jack

or terminals of an external amplifier.

3. Depress the play button and adjust the volume

and tone controls of the recorder and external

amplifier to the desired listeninglevel andequal
