DESCRIPTION
UNPACKING
The Raymer Model 810-100 is a multi-purpose 100 Watt
RMS. monaural, all silicon solid state amplifier. It is designed
for dependable continuous operation in background music,
public address, paging, and sound reinforcement systems.
Provision has been made for a choice of two microphone
inputs and one music input; or for one microphone, one
auxiliary and one music input. All inputs are unbalanced.
Mic-1 which comes wired for high impedance may be con¬
verted to a balanced low impedance microphone input by
the use of a RAYMER plug in transformer Model MT-3 or
to a 500/600 ohm balanced telephone line input by means
of RAYMER plug in transformer Model TT-4.
Mic-2 may be switched for either Hi-Z or Lo-Z micro¬
phone. Provision has also been made fora choice of one of
two separate sources to be connected to the Music input.
The Music or Aux inputs are high impedance and are for use
with a tuner, a high output ceramic or crystal phono, a tape
recorder with its own preamp, or other auxiliary equipment
The amplifier also features an electronic Music Mute
(Precedence) circuit in place of a relay to quickly fade out
the music while paging; after the page, the music is smoothly
restored. The music fade feature operates only on the music
inputs.
Model 810-100 is provided with a switch to protect
trumpet speaker diaphragm(s) from damage when used on
low frequency signals. The amplifier has a master gain con¬
trol, as well as separate bass and treble controls, which may
be used to compensate for room and speaker characteristics.
The amplifier has provision for 4 and 8 ohm unbalanced
speaker terminals as well as 25 volt and 70 volt balanced or
unbalanced lines.
A unique feature of the amplifier is a red LED overload
indicator, which when lit provides a visual warning that the
amplifier is operating improperly. This may be caused by a
mismatched condition, overload, or oscillation which over¬
drives the output transistors beyond safe operating limits
and could cause component damage.
Model 810-100 has IN and OUT jacks for connecting
an equalizer or similar equipment, also for connecting two
or more 810-100 amplifiers so that they may be operated
simultaneously to deliver a total power in multiples of 100
watts into a speaker line.
The unit is to be removed carefully from the carton and
inspected for any possible damage in transit. If there.is any
evidence of any damage which might have occurred in ship¬
ment, immediately notify your supplier, or the transporta¬
tion company which delivered it.
Claims for damage sus¬
tained in transit must be made upon the carrier. Save all
packing material for inspection by the claim agent who will
furnish you with the proper forms and will also give you
the necessary instructions for filing a claim.
In addition to the unit the carton should contain a
warranty registration card. To insure proper servicing and
to protect your rights under the warranty, be sure to fill in
the warranty registration card and mail to the factory
within 10 days.
INSTALLATION
Model 810-100 amplifier has ample vents for normal
ventilation; however, it should be placed so as to permit
free air flow around the unit.
DO NOT PLACE ANY
OBJECT ON TOP OF THE COVER OR IN ANY WAY
BLOCK THE AIR FLOW OF THE VENTS.
DO NOT
STORE OR OPERATE THE AMPLIFIER in areas where
the ambient temperature exceeds 140°F.
The amplifier may be mounted in a 3%" vertical panel
space in a rack, using a Raymer RPK-5 rack mounting kit.
Should multiple units be stacked, or heat generating units
be installed immediately above or below the amplifier(s),
then at least a 2" spacing must be provided between these
units for adequate ventilation.
The amplifier has an AC line cord with a 3 prong plug.
The line cord should be plugged into a 3 wire grounded
105 to 120 volt 60Hz AC outlet.
This will also ground
the amplifier.
The power switch will turn on the amplifier as well as
any auxiliary equipment connected to the AC receptacle
on the rear panel, and the green LED indicator lamp on
the front panel will light.
The AC receptacle on the rear panel is a 3 wire grounded
outlet which can supply power to accessory or auxiliary
equipment. Any auxiliary equipment connected to this AC
receptacle is controlled by the POWER on-off switch so
that turning off the power on the unit turns off all
equipment.
