HOW TO USE THIS MANUAL

As you read this manual, you’ll nd gures and diagrams
to help you understand and visualize what you’re reading.
You’ll also nd numerous icons that serve as cues to ag
important information or warn you against improper or po­tentially harmful activities. These icons include:

A NOTE identies an important or useful
piece of information relating to the topic

under discussion.

A TIP offers a helpful tip relevant to the topic
at hand.

A CAUTION gives notice that an action can

have serious consequences and could cause
harm to equipment or personnel, delays, or other
problems.

The UPJ-1P’s low-frequency section employs a 10-inch
neodymium magnet cone driver, while the high-frequency
section utilizes a 0.75-inch exit, 3-inch diaphragm compres­sion driver of proprietary design. The VariO horn allows
quick rotation to provide a 80° x 50° coverage pattern in ei­ther the horizontal or the vertical plane. A two-channel class
AB power amplier with complementary MOSFET output
stages provides a total output of 300 watts for the low- and
high-frequency sections.

The UPJ-1P cabinet's end plates provide unprecedented
mounting, ying and arraying exibility, and are made of
heavy duty, high-strength, corrosion-resistant 6061-T6
aluminum. Strategically placed M8 threaded points allow
simple mounting using eyebolts or directly to third party
pole assemblies. Available QuickFly® rigging options — in­cluding an array adapter (also made from 6061-T6 alumi­num), yokes, and “L”-brackets — attach easily and securely
to the aluminum end plates allowing UPJ-1P to be mounted
or own, either as a single cabinet or in arrays. The optional
RMS™ remote monitoring system module allows com­prehensive monitoring of all key system parameters on a
remote RMS host PC.

INTRODUCING THE UPJ-1P COMPACT VARIO™ LOUDSPEAKER

The UPJ-1P compact VariO loudspeaker combines the
advantages of being self-powered with the placement
and arraying exibility afforded by a VariO rotatable horn.
Remarkably compact and lightweight, the UPJ-1P (Figure
i.1) produces a robust peak power output of 128 dB SPL
at 1 meter, making it suitable for use either as a primary
loudspeaker in small rooms or as a ll, delay, effects or un­der-balcony loudspeaker in any type of large or distributed
system application.

NOTE: Read this entire manual carefully

before conguring and deploying a UPJ-1P
system. In particular, pay careful attention to the
sections about safety issues.

CHAPTER 1: POWER REQUIREMENTS

CHAPTER 1

Self-powered and compact, the UPJ-1P combines ad­vanced loudspeaker technology with equally advanced
power capabilities. Understanding power distribution, volt­age and current requirements, as well as electrical safety
issues, is critical to the safe operation of the UPJ-1P.

AC POWER

The UPJ-1P uses a PowerCon 3-pole AC mains system
with locking connectors to prevent accidental discon­nection. It may also be daisy-chained by using the grey
connector (Figure 1.1) to loop units together. The blue
connector serves as the power input; to loop additional
units, simply attach a cable from the grey connector of the
rst loudspeaker to the blue connector of the second, and
so on. One looping connector is included with each UPJ­1P. Optional assembled looping cables can be purchased
from Meyer Sound.

Blue

Grey

The UPJ-1P can withstand continuous voltages up to
264 V and allows any combination of voltage to GND (that
is, neutral-line-ground or line-line-ground).

CAUTION: Continuous voltages higher than

264 V may damage your UPJ-1P.

Voltage Requirements

The UPJ-1P operates safely and without audio discontinu­ity if the AC voltage stays within the operating window of
90-264 V AC, at 50 or 60 Hz.

After applying AC power, the system is muted while the
circuitry charges up and stabilizes. During the next two
seconds the following events occur:

1. The fan turns on.

2. The main power supply slowly ramps on.

3. The green On/Temp LED on the user panel lights up,
indicating that the system is enabled and ready to
pass audio signals.

Figure 1.1. You can daisy-chain UPJ-1P loudspeakers using the grey
connector.

CAUTION: Do not loop more than four

UPJ-1Ps from the loop out connector when
connected at 115 V and not more than eight when
driven at 230 V.

CAUTION: Be sure to select the correct

power plug for the AC power in the area in
which you operate your UPJ-1P loudspeaker.

When AC power is applied to the UPJ-1P, its Intelligent
AC™ power supply automatically selects the correct
operating voltage, allowing it to be used internationally
without manually setting voltage switches. Intelligent AC
performs the following protective functions to compensate
for hostile conditions on the AC mains:

 Suppresses high-voltage transients up to several kilo-

volts

 Filters common mode and differential mode radio

frequencies (EMI)

CAUTION: If the On/Temp LED does not

illuminate or the system does not respond
to audio input after ten seconds, remove AC power
immediately. Verify that the voltage is within the
proper range. If the problem persists, please con­tact Meyer Sound or an authorized service center.

If the voltage drops below the low boundary of its safe
operating range (brownout), the UPJ-1P loudspeaker uses
stored energy to continue functioning briey, and shuts
down only if voltage does not rise above the low bound­ary before storage circuits are depleted. How long the
loudspeaker will continue to function during brownout
depends on the amount of voltage drop and the audio
source level during the drop.

If the voltage increases above the upper boundary of the
range, the power supply can be damaged.

NOTE: It is recommended that the supply

be operated in its rated voltage window at
least a few volts away from the extreme points.
This ensures that AC voltage variations from the
service entry – or peak voltage drops due to cable
runs – do not cause the amplier to cycle on and
off or cause damage to the power supply.

 Sustains operation temporarily during low-voltage

periods

Current Requirements

Each UPJ-1P requires approximately 3 A rms max at 115
V AC for proper operation. This allows up to ve UPJ-1Ps
to be powered from one 15 A breaker at 115 V and up to 9
loudspeakers at 230 V.

The UPJ-1P presents a dynamic load to the AC mains,
which causes the amount of current to uctuate between
quiet and loud operating levels. Since different cables and
circuit breakers heat up at varying rates, it is essential to
understand the types of current ratings and how they cor­respond to circuit breaker and cable specications.

The maximum long-term continuous current is the maxi­mum rms current during a period of at least ten seconds.
It is used to calculate the temperature increase in cables,
in order to select a cable size and gauge that conforms to
electrical code standards. It is also used to select the rating
for slow-reacting thermal breakers.

The burst current is the maximum rms current during a
period of approximately one second, used to select the
rating of most magnetic breakers and to calculate the peak
voltage drop in long AC cables according to the formula:

NOTE: For best performance, the AC cable

voltage drop should not exceed 10 volts, or
10 percent at 115 volts and 5 percent at 230 volts.
Make sure that even with the AC voltage drop,
the AC voltage always stays within the operating
ranges.

The minimum electrical service amperage required by a
UPJ-1P system is the sum of each loudspeaker’s maximum
continuous rms current. An additional 30 percent above the
minimum amperage is recommended to prevent peak volt­age drops at the service entry.

Power Connector Wiring

The UPJ-1P loudspeaker requires a grounded outlet. It is
very important that the system be properly grounded in or­der to operate safely and properly. Use the AC cable wiring
diagram in Figure 1.2 to create international or special-pur­pose power connectors:

V pk (drop)= I pk x R (cable total)

The ultimate short-term peak current is used to select the
rating of fast reacting magnetic breakers.

Use Table 1.1 below as a guide when selecting cable gauge
size and circuit breaker ratings for your operating voltage.

or colored black.

 Connect the brown wire to the terminal marked with an

L or colored red.

 Connect the green and yellow wire to the terminal

marked with an E or colored green or green and yellow.
