Meyer Sound updates UPQ point source loudspeakers
Meyer Sound has used technologies developed for its LEO family line array systems to update its UPQ point source loudspeakers. The company has added a new class D amplifier, new on-board signal processing for optimised frequency and phase response, and a 6kg overall weight reduction. The current UPQ-1P (80-degree x 50-degree) and UPQ-2P (50-degree x 50-degree) have been re-designated as, respectively, UPQ-D1 and UPQ-D2. A third variant, the UPQ-D3, offers a new 80-degree x 80-degree coverage option. All three variants retain the same exterior cabinet dimensions and rigging points as current UPQ models.
All three new variants incorporate the same proven driver complement as the prior versions. The low frequency section relies on a 15-in neodymium magnet cone driver while high frequencies are reproduced by a 4-in diaphragm compression driver. Both drivers are manufactured at Meyer Sound’s Berkeley campus.
The new two-channel class D amplifier is designed for high efficiency with reduced current draw and produces a total peak output power of 1800 watts. A new generation of phase-corrected signal processing is designed to provide flatter frequency and phase response.
All UPQ-D series models have an operating frequency range of 53 Hz to 19 kHz with phase response of 80 Hz to 18 kHz ± 45-degrees. Linear peak SPL is 133 dB measured with M-Noise, free-field at 4 m referred to 1 m. Meyer Sound says the Constant-Q horn exhibits a gentle and uniform rolloff characteristic for predictable behaviour when plotting room coverage. Performance specifications are the same for all three variants except for the high frequency horn patterns.
The new input module provides loop-through XLR-F and XLR-M connectors and parallel powerCON 20 AC line connectors. The optional RMS remote monitoring system module provides monitoring of loudspeaker parameters from a host computer running Compass software. An optional XLR 5‑pin connector is available to accommodate both balanced audio and RMS signals. Due to significant changes in the internal cabinet structure, the new amplifier and processing module cannot be retrofitted into current UPQ loudspeakers.
The redesigned cabinet retains the original size, grille frame, and is compatible with all the rigging options of previous UPQ products.
The new UPQ series loudspeakers are suited to portable and installed applications including main loudspeakers in small and mid-sized venues to fill systems in larger venues.
