Meyer Sound UPJunior Ultra Compact Vario Loudspeaker
Ultra Compact and Extraordinary
Peak Power In A Small Package
Meyer Sound UPJunior brings the sonic signature, versatile rigging, and extraordinary power-to-size ratio of the UPJ to a smaller package, combining the advantages of a self-powered system with the placement and arraying flexibility afforded by a Vario rotatable horn.
Two Options For Tight Spaces
Choose either the Meyer Sound UPJunior or UPJunior-XP with the added flexibility of external DC power and lengthy cable runs without AC conduits. The UPJuniors integrate seamlessly with UPM and UPJ loudspeakers.
Precise Coverage Control
Our Constant-Q horn affords uniform response throughout coverage area, while the Vario rotatable horn allows loudspeakers to be oriented horizontally or vertically, adding great flexibility to your design.
Applications And Venues
Use the Meyer Sound UPJunior for portable and installed AV systems, theatrical sound reinforcement, frontfill and under-balcony fill, conference centers, presentations, ballrooms, or houses of worship.
Fitting Robust Power into Tight Spaces
Meyer Sound UPJunior : Versatile And Ultracompact
Though remarkably compact and lightweight, the Meyer Sound UPJunior delivers robust peak power output making it suitable for use as either a single, primary loudspeaker or within multicabinet horizontal and vertical arrays.
UPJUNIOR-XP: With Intelligent DC
The UPJunior-XP, with IntelligentDC technology, offers the same sonic signature, robust peak power output, and rotatable Vario horn as the Meyer Sound UPJunior but with the added flexibility of external DC power and lengthy cable runs without AC conduits.
Intelligent DC For Long Cable Runs
With IntelligentDC technology, the UPJunior-XP receives DC power and balanced audio from a single loudspeaker connector. Powering the unit from an external source eliminates the need for wiring conduits while still preserving the advantages of self-powered systems.
Robust Cabinet & Mounting Hardware
The Meyer Sound UPJunior cabinet is coated with a black textured finish and includes heavy-duty, corrosion-resistant aluminum end plates with threaded attachment points for basic eyebolt rigging and third-party pole assemblies. Other options include weather protection and custom colors for fixed installations and installations with specific cosmetic requirements.
Meyer Sound’s UPJunior ultracompact Vario loudspeaker brings the sonic signature, flexible rigging, and extraordinary power-to-size ratio of the award-winning UPJ-1P to an even more compact package suitable for a broad range of applications. The Meyer Sound UPJunior combines the advantages of self-powered systems with the placement and arraying flexibility afforded by an 80° x 50° Vario rotatable horn and QuickFly rigging.
Though remarkably compact and lightweight, the Meyer Sound UPJunior delivers a robust peak power output of 126 dB SPL at 1 meter, making it suitable for use as either a single, primary loudspeaker or within multicabinet horizontal and vertical arrays. Applications include AV presentations, small- to medium-sized sound reinforcement systems, fill, delay, effects, and under-balcony coverage, as well as distributed systems.
The UPJunior was designed for flexibility. Whether oriented vertically or horizontally, its Vario horn can be easily rotated to obtain the optimum horizontal and vertical coverage in any situation. In size, weight, and output, the UPJunior integrates seamlessly with the UltraSeries UPM-1P/2P and UPJ-1P loudspeakers.
As a self-powered loudspeaker, the UPJunior incorporates a two-channel, class AB/bridged power amplifier and sophisticated control circuitry housed within the cabinet, dramatically simplifying setup and installation. The UPJunior’s on-board amplifier delivers 300 watts of total burst power. The optional RMS remote monitoring system module allows comprehensive monitoring of all key system parameters from a Windows-based computer.
The UPJunior’s low-mid frequency section employs an 8-inch neodymium magnet cone driver, while the high-frequency section utilizes an efficient 0.75-inch exit, 2-inch diaphragm compression driver. Both drivers are designed and manufactured by Meyer Sound in Berkeley, Calif.
The UPJunior is extraordinarily versatile in the number of ways it can be mounted, flown, and arrayed, allowing it to be used as either a main loudspeaker or fill loudspeaker, or even as a stage monitor. The UPJunior’s cabinet includes end plates made of heavy-duty, high-strength, corrosionresistant 6061-T6 aluminum, complete with threaded M8 attachment points for basic eyebolt rigging or third-party pole assemblies. QuickFly rigging options including the MAAM-UPJunior array adapter (also made from 6061-T6 aluminum), the MUB-UPJunior U-bracket, and the MYA-UPJunior mounting yoke assembly.
Other options include weather protection for fixed applications and custom color finishes for specific cosmetic requirements.
The loudspeaker shall be a self-powered, full-range system. The transducers shall consist of an 8-inch diameter cone driver and a 2-inch diaphragm compression driver on an 80° x 50° horn. The horn shall allow rotation to provide the wider coverage pattern in either the horizontal or vertical plane relative to the cabinet’s vertical axis.
The loudspeaker system shall incorporate internal processing electronics and a two-channel amplifier. Processing functions shall include equalization, phase correction, signal division, and driver protection for the high- and lowfrequency sections. The acoustical crossover point shall be 3.5 kHz. Each amplifier channel shall be class AB/bridged with complementary MOSFET output stages. Burst capability shall be 300 watts total into a nominal load of 4-ohms low channel and 12-ohms high channel. Distortion (THD, IM, TIM) shall not exceed 0.02%.
Performance specifications for a typical production unit shall be as follows, measured at 1/3 octave resolution: Operating frequency range shall be 70 Hz to 20 kHz. Phase response shall be ±45° from 250 Hz to 18 kHz. Maximum SPL shall be 126 dB at 1 meter. Coverage (–6 dB points) shall be 80° x 50°, horizontal or vertical dependent on horn orientation.
The audio input shall be electronically balanced with a 10 kΩ impedance and accept a nominal 0 dBV (1 V rms, 1.4 V peak) input signal. Connectors shall be XLR (A-3) type with male input and female loop-through output. RF filtering shall be provided, and CMRR shall be greater than 50 dB and typically 80 dB (50–500 Hz).
The internal power supply shall perform automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. Powering requirements shall be nominal 100 V, 115 V or 230 V AC line current at 50 Hz or 60 Hz frequency. Current draw during burst (1 sec) shall be 2.9 A at 115 V, 1.7 A at 230 V and 3.2 A at 100 V. Current inrush during soft turn-on shall not exceed 15 A at 115 V. The AC power connector shall be a locking connector with looping output.
The loudspeaker system shall provide facilities for installing Meyer Sound’s optional RMS remote monitoring system.
All loudspeaker components shall be mounted in an acoustically vented trapezoidal enclosure constructed of premium birch plywood with a hard black textured finish.
