Allen & Heath used NAMM to launch Qu-Pac, a compact digital mixer with a built-in touchscreen and iPad control app. Designed for live music and installed sound applications, Qu-Pac is a freestanding or rack-mount mixer, offering 16 mono inputs, three stereo inputs and 12 mix outputs on the rear panel. The model can also be expanded up to 38 in/28 out by connecting to Allen & Heath’s family of remote AudioRacks over Cat5. The mixer offers total recall of settings and preamps, multi-track recording to USB via Qu-Drive, a choice of personal monitoring solutions, channel ducking, multichannel USB streaming and the iLive FX Library. The Qu-Pad iPad app offers wireless control of the key parameters and settings, freeing the

user to mix the show from anywhere in the venue. Qu-Pac’s high-resolution, full colour 5in touchscreen allows access to all functions, providing a simple interface and a backup in the event of WiFi connection problems. As well as stereo recording or playback from a USB key, the built-in, 18-channel Qu-Drive can record and playback multi-track and stereo audio .wav files to a USB key or drive. Qu-Pac’s 32 x 32, Windows and Mac-compliant USB streaming interface also makes it “the perfect recording solution for tracking, monitoring and overdubbing” in the studio, the firm says.


The RNDI active transformer direct interface and R6 Six Space 500 Series were both on show at NAMM last month. The RNDI utilises a custom Rupert Neve-designed transformer and a Class A-biased discrete FET amplifier to balance an instrument signal – whether straight from a bass guitar or a 1,000W amplifier – with sonics extending beyond 100kHz. The unit can be used in two modes: speaker mode, where the DI is connected post-power amp; and instrument mode, where the instrument is connected to the DI directly. In speaker mode, the RNDI can handle the output of a 1,000W power amplifier (92 Vrms or 266Vp-p) to capture the full tone of the instrument, preamplifier, EQ, inserts, and the amplifier’s output stages before it hits the speakers, allowing the sound engineer to avoid any bleed or unwanted tone. In instrument mode, the RNDI’s high input headroom of +21.5dBU is capable of handling not only instruments, but professional line level sources

like interfaces, CD players and drum machines without a pad. This allows the RNDI to serve as a way to ‘re-preamp’ any previously recorded track using an interface and preamp. The R6 Six Space 500 Series is a rack with more than double the required current for a six-space chassis to prevent the power rails from failing under a higher than expected load. The unit also features LED current metering, a doubleshielded internal power supply and eight channels of balanced I/O options including DB-25, XLR and TRS that may be used interchangeably, all within a solid steel chassis with bumpers to support the unit in both horizontal and vertical configurations.


New from Sennheiser is the evolution wireless D1, a range of digital wireless microphone systems for vocals and instruments. Designed to make frequency setting simple, the units feature transmitters and receivers that automatically pair suitable transmission frequencies and configure gain automatically, with automatic co-ordination between D1 systems. For multiple systems, receivers will synchronise themselves to accommodate up to 15 channels in an ideal RF environment. D1 operates in the licence-free 2.4GHz range, continually scanning the RF environment and hopping to another frequency if it detects any interference,

allowing co-existence with Bluetooth and WiFi systems. Menu controls include a seven-band graphic equaliser, low-cut filter, automatic gain control and a de-esser. In addition, each model employs the aptX Live codec, which promises excellent audio quality and wide dynamics for vocals, speech and instruments over the entire audio frequency range, with an overall latency of 3.9ms. D1 transmitters can be powered by either standard batteries or USBrechargeable lithium-ion ‘accupacks’. The D1 series also comprises headmic and lavalier systems and will be available from March 2015.

EV STRENGTHENS PORTABLE LOUDSPEAKER RANGE Positioned above the ZLX and ELX series and below the ETX series, the newest member of the Electro-Voice portable loudspeaker range is the EKX series. The compact package is designed for a number of sound reinforcement scenarios, and is ideal for musicians, DJs and live/club/ installed sound. The EKX series features eight models (four powered and four passive), including 12in and 15in two-way models and 15in and 18in subwoofers. The powered models offer Class D power amplifiers (up to 1,500W), delivering up to 134dB peak SPL via high-sensitivity transducers. On-board signal processing, four presets, visual monitoring, three-band EQ and more are controlled via a single-knob user interface, with menu navigation via an LCD display. The powered models also have EV-exclusive Cardioid Control Technology, allowing subwoofer output to be steered towards the audience with up to a 35dB reduction on stage when multiple subs are deployed, while a Signal Synchronized Transducers waveguide design on the

full-range models ensures precise and consistent coverage. Each model is lightweight and built to reduce distortion and accentuate bass extension, featuring compact 15mm wood enclosures with internal bracing, a durable EVCoat finish, aluminium pole-mounts and all-metal handles, proving ideal for portable and installed applications. The EKX series will begin shipping in Spring 2015.
