Introduction

The Sierra Video -10 Audio and Video distribution amplifiers offer high performance
solutions to your video and audio distribution needs. A wide variety of plug-in modules
can be used in a choice of two 3RU (801012 or 801028) or a 1 RU (801014) frame for
video. And a 3RU audio frame for stereo or mono configurations.

The frames provide low voltage AC input to each module. The Series 10 modules can be
removed or re-inserted with power to the frame either on or off.

The 801012 video frame has 10 separate outputs for each module with slots for up to 10
modules, while the 801028 video frame has 4 outputs for each module with slots for up to
20 modules. Only the outputs which are used need to be terminated.

Chapter

1

The 801017 audio frame has 10 balanced outputs for each module with slots for up to 10
modules. Inputs and outputs can be wired for balanced or unbalanced operation.

Warnings & Safety Regulations

The information in the following section provides important warnings and safety
guidelines for both the operator and service personnel. Specific warnings and cautions
may be found throughout this manual. Please read and follow the important safety
precautions noting especially those instructions relating to risk of fire, electrical shock and
injury to persons.

Any instructions in this manual that require opening the equipment cover or enclosure are
intended for use by qualified service personnel only. To reduce the risk of electrical
shock, do not perform any servicing other than what is contained in the operating
instructions unless you are qualified.

Warnings

 Heed all warnings on the unit and in the operating instructions.
 Disconnect AC power before installing any options.
 Do not use this product in or near water.
 This product is grounded through the grounding conductor of the power

cord. To avoid electrical shock, plug the power cord into a properly wired
receptacle before connecting inputs and outputs.

Warnings (continued)

 Route power cords and other cables so that they are not likely to be

damaged, or create a hazard.

 Dangerous voltages exist at several points in this product. To avoid personal

injury, do not touch unsafe connections and com ponents when the power is
on.

 To avoid fire hazard, use only the specified type, correct voltage, and

current rating of fuse. Always refer fuse replacement to qualified service
personnel.

 Have qualified personnel perform safety checks after any completed service
 This is an FCC class A product. In a domestic environment, this product

may cause radio interference, in which case the user may be required to take
necessary measures.

Cautions

 Use the proper AC voltage to supply power to the switcher. When installing

equipment, do not attach the power cord to building surfaces.

 To prevent damage to equipment when replacing fuses, locate and correct

trouble that caused the fuse to blow before applying power.

 Use only the recommended interconnect cables to connect the switcher to

other frames.

 Follow static precautions at all times when handling the equipment.
 Leave the side, top, and bottom of the frame clear for air convection cooling

and to allow room for cabling. Slot and openings in the frame are provided
for ventilation and should not be blocked.

 Only an authorized Sierra Video technician should service the switchers.

Any user who makes changes or modifications to the unit without the
expressed approval of the Sierra Video will void the warranty.

Power Supply Cords

North American Power Supply Cords

This equipment is supplied with North American power cords with molded grounded plug
(NEMA-15P) at one end and molded grounding connector (IEC 320-C13) at the other
end. Conductors are CEE color coded, light blue (neutral), brown (line), and green/yellow
(ground). Operation of the equipment at voltages exceeding 130VAC will require power
supply cords that comply with NEMA configurations.

International Power Supply Cords

If shipped outside North America, this equipment is supplied with molded ground
connector (IEC 320-C13) at one end and stripped connecto rs (50/5mm) at the other end.
Connections are CEE color coded, light blue (neutral), brown (line), and green/yellow
(ground). Other IEC 320-C13 type power cords can be used if they comply with safety
regulations of the country in which they are installed.

EMC Regulatory Notices

Federal Communications Commission (FCC) Part 15 Information: This device complies
with Part 15 of the FCC standard rules. Operation is subject to the following conditions:

This device may not cause harmful interference
This device must accept any interference received including interference that may cause

undesirable operations.

Delivery Damage Inspection

Carefully inspect the frame and exterior components to be sure that there has been no
shipping damage. Make sure all modules are seated correctly and have not detached
during shipment.

Factors Affecting Quality of Results

There are many factors affecting the quality of results when signals are transmitted from
a source to a destination.

Signal cables — Use only the best quality cables to avoid interference and

degraded signal quality and elevated noise levels.

Sockets and connectors of the sources and destinations — Use only the

highest quality, since "zero ohm" connection resistance is the target.
Connectors should also match the required impedance (75 ohm in
video) to minimize return loss.

SERIES 10 DA

Amplifying circuitry — Must have quality performance when the desired

end result is high linearity, low distortion, and low noise.

Distance between sources and destinations — Plays a major role in the final

result. For long distances (over 15 meters) between sources and
destinations, special measures should be taken to avoid high frequency
cable losses. These measures include using higher quality cables and/or
adding line cable equalizing amplifiers.

Interference from neighboring electrical appliances — These can have an

adverse affect on signal quality. Balanced audio lines are less prone to
interference, but unbalanced audio should be installed away from any
main power lines, electric motors, transmitters, etc. even when the
cables are shielded.

CAUTION!

Only an authorized Sierra Video technician can service these products. Any user who
makes changes or modifications to the unit without the expressed approval of the
manufacturer will void the warranty

Use the proper AC voltage to supply power.
