OPERATING INSTRUCTIONS
MODEL 811-100 AMPLIFIER
WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS RECEIVER TO RAIN OR MOISTURE.
DESCRIPTION
The Raymer Model 811-100 is a monaural 100 watt
RMS all silicon solid state amplifier. It is designed for
dependable continuous operation in background music,
public address, paging and sound reinforcement
systems.
The input of the amplifier is high impedance un¬
balanced with a sensitivity of .4 volts. The input may be
changed to a 500/600 ohm balanced line input with the
use of a RAYMER plug-in transformer Model TT-4A.
The outputs provided on the Model 811-100 are 4 and 8
ohms unbalanced as well as 25 volts and 70 volts which
may be connected for either balanced or unbalanced
operation.
A trumpet protect switch is provided on the unit to
prevent possible diaphragm damage on trumpet speakers
caused by low frequency signals.
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 load, overload or oscillation which over¬
drives the output transistors beyond safe operating limits
and could cause component damage.
Model 811-100 has an AMPLIFIER PARALLEL jack for
connecting two or more 811-100 or 810-100 amplifiers
together so that they may be operated simultaneously to
deliver a total output power in multiples of 100 watts into
a speaker line.
UNPACKING
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 shipment, immediately notify your supplier, or the
transportation company which delivered it. Claims for
damage sustained 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 811-100 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 OB¬
JECT 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 degrees F.
The amplifier may be mounted in a 3!4" 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 ampli¬
fiers), 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.
