New Sound Reinforcement Products

Soundcraft Si Series Upgrade
The Soundcraft Si Series now offers more inputs on the Si1 and Si2 versions, plus added functionality and options. The Si1+ has 16 additional mic inputs fitted as standard, bringing the number of onboard mic inputs to 48 and processing capacity of 72 inputs to mix; the extra 16 mic input module may be replaced by an 8-in/8-out module if required. The number of option card slots increases to four, and there is now a space for an optional second (redundant) PSU. The Si2+ has the 16 mic input module as standard (also swappable with the 8-in/8-out module), which extends the onboard mic input count to 64, with an input-to-mix capacity of 80. All three models, including the Si3+, gain a word clock output connector, and all models can use the range of Si optional interface cards including MADI (optical or Cat-5), AES/EBU, CobraNet and Aviom A-Net.

Mackie ProFX16, ProFX22
Geared for mid-sized venues, the Mackie ProFX16 16-channel and PROFX22 22-channel mixers feature low-noise, high-headroom preamps with LED metering and 60mm faders on each channel. Each channel also offers 3-band EQ. Integrated 32-bit RMFX™ effects processor with 16 “gig-ready” FX and 7-band graphic EQ allow for tuning of mains or monitors. The built-in USB interface allows the user to record the show and stream back music for breaks or for integration into the mix. A solid-steel chassis with protective ABS sidecheeks offers impact resistance.

Avlex MIPRO ACT-82a
The new Avlex ACT-82a ($TBD) dual-channel encrypted digital diversity receiver offers expanded 120MHz bandwidth, second-generation DSP technology and 24-bit/44.1kHz audio quality. Carrier frequency range of UHF is 482 to 602 MHz. System latency is less than 2.9 ms, while THD is less than or equal to 0.04 percent @ 1 kHz. Audio frequency response extends from 20-20k Hz. For signal stability, it offers MIPRO’s DigitnamicPlus™ technology to eliminate compander noise, as well as integrated SmartEQ™ preset and user-defined mic capsule EQ. It is expected to be available Q3, 2011.

Powersoft M Series DSP+ETH
The new M Series DSP+ETH amplifiers provide access to Powersoft’s digital signal processing engine technology, Ethernet connectivity, and system monitoring and control through the company’s Armonía Pro Audio Suite™ software. The unit features 24-bit/48kHz AD/DA converters with 56-bit for internal processing. With two inputs and outputs each for the 2-channel version, and four inputs and outputs each for the 4-channel version, the system offers per-channel five bi-quad filters for system equalization, eliminating the need for outboard equalizers, plus two crossovers and eight bi-quad filters. Each channel has dual dynamic processors with arbitrary input/output curve and adjustable time constants. To accommodate speaker time alignment, a range from zero to 10ms adjustable delay makes timing the LF vs. HF speakers easy. The DSP engine delivers up to 114dB(A) signal-to-noise ratio with a 1ms processing delay time. It also provides such limiters as peak with variable ratio, RMS and frequency-shaping RMS.
