160 GUIDE - AMPLIFIERS
RAM AUDIO | V SERIES
www.ramaudio.com
RAM Audio’s V Series is based on QuantaPulse technology with dual oversized high efficiency regulated switching mode power supply with PFC to deliver full performance independently of mains status. An oversized high efficiency audio power stage is responsible of audio power and quality. Forced front to back cooling through a component-free path with removable front panel dust filters guarantee reliable operation. Full LCD digital control on the front panel shows channel temperatures, attenuation or VUmetre display mode, operating time, input links, working gain and dual or bridge mode. Equipped with low latency 24bits 96kHz high performance DSP with post-DSP signal links, ethernet connection and digital AES3 inputs, the series includes three two-channel models from 6,000W to 12,000W and four 4-channels models from 9,000W to 12,000W, all of them in a reduced and light casing to make handling easy.
RCF | UP 1121

UP 1121 is a 120W power amplifier with a single balanced ‘line’ level audio input. The amplifier output is available either for low impedance loudspeakers (minimum four ohms) or 100V - 70V constant voltage line (for loudspeakers having 100 - 70V transformers). In addition to the connection to the mains, it can also be powered by batteries, in order to ensure its proper operation even when the mains supply is unavailable.
SAE AUDIO | PQM SERIES
www.saeaudio.com
SAE Audio introduces the new PQM high-end four-channel amplifier series, designed with the most rigorous sound reinforcement applications in mind, where high SPL and excellent sound quality is required. SAE Audio’s self-developed Class-I is a digital class variation capable of accurately reproducing the input signal, thus achieving an excellent sound quality like Class-AB and extremely high efficiency like Class-D. The output stage circuitry, specifically developed for the PQM Series, can continuously work with even two ohms thus delivering up to 2,500W per channel on the PQM13 and 1,600W per channel on the PQM8. A high-efficiency stabilised SMPS power supply is built in the PQM to ensure the power modules have a strong support for the long-term full power use even on AC power fluctuations. On the front panel it features gain knobs and highly bright channel dedicated signal dB metres, indicators for bridge or parallel working mode, clipping, protection, continuous VHF signal input and overheating. All four XLR signal input connectors on the back panel have XLR link con- nectors for amplifier stacking, and DIP switches can be used to set input sensitivity. For signal output the PQM solely mounts SpeakOn connectors.
TOA | DA-250
www.toa.eu
The TOA DA-250 multi-channel power amplifier offers a wider choice of power ratings, advanced digital Class-D amplification circuitry, and a highly efficient AC mains to output power ratio, for the complete technological superiority it takes to support long-term installation applications. The energy-efficient, space-saving amplifiers are designed to combine high levels of performance and efficiency, and are well-suited to ensure sound reinforcement reliability in a wide range of venue types. The low-impedance models are ideal for multi-zone applications such as presentation and press-conference rooms, restaurants and similar-sized locations.
YAMAHA | XMV SERIES
www.yamahaproaudio.com
The eight channel XMV Series of amplifiers combines Class-D efficiency with the flexibility of Dante technology and Yamaha’s YDIF cascade bus and comprises four models. The XMV8140 and XMV8280 are equipped with the YDIF cascade bus, providing a simple intra-rack connection using Cat5 cable for an easy to use, 16-channel bus. Meanwhile the XMV8140-D and XMV8280-D feature Dante technology, allowing CIS systems to share audio with up to 40 subnets (using an audinate netspander), enabling them to merge with other complex professional audio systems simply and efficiently. Installed sound applications often demand both high and low impedance connectivity in the same venue, requiring separate, dedicated amplifiers or an external transformer. XMV power amplifiers eliminate this complexity by the ability to operate in both high-impedance (70V / 100V line) or low-impedance modes simultaneously. They also enable both 70V and 100V operation for every pair of channels by simply selecting the preferred mode using the dip switches on the rear panel. High impedance operation often requires the use of two combined channels in bridge mode, but with XMV amplifiers, 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels. Double Power Mode effectively doubles the output power of selected channels in order to drive speakers with higher output power.
