Coomber 2020 Operating Instructions

Operating Instructions: 2020, 2025, 2060
Power From Mains
A Mains ON/OFF switch is found on the side panel. A red power light
(14), on the top panel, will illuminate when the supply is switched on.
EXT D.C. Input Socket (13)
A standard Roka connector allows the equipment to operate from an
external DC supply of between 12 and 24 volts. The red "Power" light
(14) below the socket will illuminate if the polarity is correct. Always
disconnect the DC source when not in use.
The Coomber 1959 rechargeable battery, fitted with fused lead and
connector is suitable for use with this model. A battery charger,
Coomber 1958, should be used to recharge the battery as necessary.
Internal Rechargeable Battery (Optional - 2060/R models)
The 2060/R model incorporates a rechargeable battery and battery charg-
er circuit allowing the 2060/R to be used away from a mains power
source. A panel located on the side of the unit controls battery use.
When fully charged, the Battery OK light will illuminate when the
INTERNAL BATTERY switch is switched on. When the Battery OK light
flashes, the battery requires charging.
To charge the battery, simply plug the 2060/R into the mains and
switch on the Mains switch - the POWER light (14) will illuminate on
the top panel. Ensure that the INTERNAL BATTERY switch is switched
to OFF/CHARGE. The Charging light will illuminate and remain on until
the battery is fully charged. The light will then extinguish.
To maximise battery life, never let the battery become fully dis-
charged. Recharge it as soon as the Battery OK lamp begins flashing.
The battery panel also incorporates a Roka connector, allowing one
Coomber 1959 battery to be recharged at a time.
Cassette Mechanism
The tape deck has 'one touch' record, cue and review facilities, and full
Autostop. NOTE: It is important to keep the pinch wheel and heads
clean. If in doubt consult your audio visual advisor.

Recording
When recording, the record level is automatically set to give optimum
performance, whether from the AUX or MICROPHONE inputs. If the
RECORD key on the cassette mechanism cannot be depressed, check
that the left-hand safety tab on the top edge of your cassette has not
been removed to protect an original recording. If you wish to reuse the
cassette for recording, replace the removed tab with self adhesive
tape.
Useful Tips
a. You may find that a small amount of distortion is heard at the start
of a recording, especially if the signal to be recorded is strong
(loud). The automatic level control (ALC) attunes itself to the general
level of sound in a room - so for the best recordings, allow the ALC
to settle before recording commences. To do this, simply press the
PAUSE key followed by the RECORD key. The ALC will monitor the
sound levels and set itself. Release the PAUSE key to start the
recording.
b. Reset the turns counter (15) to zero whenever you wish to be able
to return to the start of a particular passage.
Playing a Pre-recorded Tape
Open the cassette door with the STOP/EJECT key and insert a pre-
recorded tape. Close the door and press the PLAY key. Adjust the TAPE
VOLUME (2), BASS (3) TREBLE (4), controls to suit. To pause the tape,
press the PAUSE key.
Input Sockets (6-7-8-9)
Public Address
One or two microphones can be connected to sockets (6) and/or (7).
Adjust INPUT VOLUME (1), BASS (3) and TREBLE (4) to suit.
Microphones may be used together effectively providing they have
similar characteristics.
Coomber 1902 or 1903 microphones are ideal for public address use.
Variable Speed
(Optional - 2020 & 2060 models)
A dial on the side panel varies the speed
of cassette playback from -25% to
+10%.
During recording, the speed control is
automatically overridden.
