Additional Information
YourRenkus-Heinz ST loudspeaker was carefully tested and fully inspected before leaving our factory and
should have arrived in perfect condition. Please carefully inspect your loudspeaker and its shipping carton for
any noticeable damage and if any damage is found, immediately notify the shipping company.
Only the consignee may institute a claim with the carrier for any damage incurred during shipping. Be sure
to save the carton and all packing materials for the carrier's inspection.
It is also a good idea to save the carton and packing material even though the loudspeaker arrived in good
condition. If shipping the loudspeaker should ever be required, it should be shipped only in its original
factory packing.

INTRODUCTION
Congratulations on your purchase of a Renkus-Heinz ST loudspeaker system. Your ST Series loudspeaker has
been designed to provide you years of trouble-free high performance listening pleasure. We hope you enjoy it.
IMPORTANTSAFETY INSTRUCTIONS
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades
with one wider than the other. Agrounding type plug
has two blades and a third grounding prong. The
wide blade or the third prong is provided for your
safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
10. Protect the power cord from being walked on or
pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
11.Make sure the power cord remains readily accessible at all times.
12. Only use attachments/accessories specified by
the manufacturer.
13. Unplug this apparatus during lightning storms or
when unused for long periods of time.
14. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in any way,such as power-supply cord or
plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate
normally,or has been dropped.
“WARNING- TO REDUCE THE RISK OF FIRE OR
ELECTRIC SHOCK, DO NOT EXPOSE THIS APPARATUSTO RAIN OR MOISTURE”
“CAUTION: THESE SERVICING INSTRUCTIONS
ARE FOR USE BY QUALIFIED SERVICE PERSONNEL ONLY. TO REDUCE THE RISK OF ELECTRIC
SHOCK DO NOT PERFORM ANY SERVICING
OTHER THAN THAT CONTAINED IN THE OPERATING INSTRUCTIONS UNLESS YOU ARE QUALIFIED TO DO SO”.
IMPORTANTMOUNTING INSTRUCTIONS
Toensure proper air movement for the cooling of the amplifier module, we recommend a minimum of 2 to 3 feet
of clearance in front of the loudspeaker and at least 3 to 4 inches of clearance from the other cabinet surfaces.
YourST Series loudspeaker was designed to be mounted in an upright position. Please do not place it on its
side on the floor.
Safety certifications do not include methods for mounting loudspeakers.
Input Connector
The female 3-pin XLR type INPUT connector connects to the amplifiers 10 K Ohms, electronically balanced input. It requires a 1.4 V signal for full rated
output.
Pin 2 is "hot" and pin 3 is "neutral". Pin 1 is chassis
ground. When the amplifier is connected to a balanced source, the shield may either be lifted or connected at the source end. The choice should be made
on the basis of minimum hum.
With an unbalanced source, connect the signal to pin
2 and source ground to pin 3 (connecting the signal to
pin 3 is not recommended. Note: Improper operation
results when only pin 2 or only pin 3 and pin 1
(ground) are used for an unbalanced input.
Looping Connector
The male 3-pin XLR type “looping” connector is used
to “loop through” to additional ST series loudspeaker
PM-3 tri-amplifiers. It has “straight through” connections from the Input connector.
Status LED’s
The LED’s indicate the amplifier’s status during operation. The Mute LED’s glow when one of the amplifier
channels is “Muted”. The Fault LED’s turn on when
one of the amplifier channels has failed and been removed from operation. The Limit LED’s show when an
amplifier channel is being overdriven and the protective circuits are being activated: green indicates normal level; yellow indicates caution and red indicates
danger.The temperature indicator glows when the
amplifier is starting to overheat.
VolumeControl
This control adjusts the loudspeaker’s output level.
When it is turned fully clockwise, the amplifier will
have its maximum voltage gain and will deliver its
rated output when driven by its rated signal.
As a general rule, setting the control in the full clockwise position provides maximum headroom; setting
the control at a lower level maximizes the signal/noise
level.
Power/Standby Switch
This switch is used to turn the amplifer “On” or place it
in “Standby”. In Standby,the amplifier is still connected to theAC Mains, but not turned “On”.
“Push ToReset” Circuit Breaker
The “Push To Reset” Circuit Breaker acts as a protective power line fuse and automatically turns the power
to the amplifier “Off” in case of overload. If the switch
shuts “Off” during normal use, push it back to the “On”
position just one time. Do not attempt to operate the
amplifier by holding the switch in the “on” position. If it
will not stay on by itself, the amplifier needs service.
WARNING
TheAC Mains must be connected to a mains
socket outlet with a protective earthing connection.
PM-3 PowerNet Tri-AmplifierModule
The heart of your PowerNet loudspeaker is the integral PM-3 tri-amplifier.It was developed by RenkusHeinz engineers as a perfect match for the loudspeaker’s high performance transducers and includes
comprehensive signal processing and protective circuitry.
