Networking the mix

Networking the mix


AVB networking is the major highlight of the StudioLive AVB Mix Systems from PreSonus. The four family members combine one or two StudioLive RM Series rack mixers, a StudioLive CS18AI Ethernet/AVB control surface and integrated control, recording and production software. The various options aim to put the I/O in an onstage, rack-mount mixing system with an integrated recording interface, Wi-Fi, and Ethernet networking, while providing a control surface at FOH with 18 touch-sensitive, motorised faders and 4x2 I/O.

The smallest member of the family is the StudioLive AVB 16AI Mix System, with one StudioLive RM16AI mixer. Moving up in scale, the StudioLive AVB 32AI Mix System features a StudioLive RM32AI. Next in line is the StudioLive AVB 48AI Mix System which calls on one of each RM model cascaded to form a 48-input, 64-channel system. Finally, the StudioLive AVB 64AI Mix System uses two cascaded RM32AIs for a 64-input system.

According to the manufacturer, it is possible to start with a single-mixer AVB Mix System and expand it later by cascading a second RM-series mixer. Both mixers in a cascaded AVB Mix System can be controlled from the CS18AI and from UC Surface touch-control software.

An associated firmware update for RM-series mixers adds a new Stage Box mode so that RM-series mixers can be used as I/O devices in conjunction with AI-series consoles. Simultaneous updates to the CS18AI and Capture 2 recording software add remote control of Capture from a CS18AI and UC Surface. The updates also provide advanced networking features, performance improvements and bug fixes for AI consoles, RM-series mixers, CS18AI, UC Surface, and Capture.

Away from mixing technology, the manufacturer has also unveiled the Studio 192 Mobile USB 3.0 22x26 audio interface and studio command center. The audio interface reportedly delivers the same functionality as the Studio 192 interface but in a smaller format aimed at studio and mobile use.

The Studio 192 Mobile records at up to 192KHz and combines two digitally controlled XMAX Class-A, solid-state mic preamps and Burr-Brown converters with 118dB of dynamic range. It offers 18 channels of digital I/O, and 16 remote-controlled microphone preamps can be added when expanded with two DigiMax DP88 A/D/A converters. The system also provides talkback control, mono and dim for the main mix output, word clock I/O, a dedicated DAC for the headphone output, and the ability to use its six balanced outputs for monitor mixing or for speaker switching.

The unit also features the same Fat Channel plugin found in PreSonus’ Studio One DAW as well as integration with the Studio One production environment, including full preamp control and zero-latency monitor mixing.

The Studio 192 Mobile offers a pair of front-panel mic/instrument inputs and two rear-panel direct-to-ADC line inputs; 16-channel ADAT Optical In and Out (eight channels at 88.1 or 96kHz); coaxial, stereo S/PDIF I/O; and BNC word-clock I/O. There are four balanced TRS outputs, balanced stereo main outputs, and a headphone amplifier with independent output, level control, and Cue Source switching.

Staying in the mobile world, but moving further down the signal chain, the manufacturer has launched its ULT-series of active loudspeakers. Designed by Presonus’ WorxAudio commercial loudspeaker division, the series includes the ULT12 and ULT15 full-range systems and the ULT18 subwoofer.

The full-range ULT12 and ULT15 feature PreSonus’ proprietary, rotatable Pivot X110 horn and a proprietary, 12- or 15-inch, low-frequency driver with a 2.5-inch voice coil. Both speakers are biamped and driven by a 1,300W (peak) Class-D amplifier. The ULT12 generates up to 132dB SPL, and the ULT15 delivers up to 136dB SPL. The cabinets feature two combo XLR and ¼-inch TRS inputs: a mic/line input with the XMAX mic preamp and a line-level-only input. The inputs have independent level control, allowing up to two audio sources to be mixed internally and summed to a balanced XLR output for daisy-chaining multiple units. There is a separate direct output for the line input channel.

The ULT18 subwoofer is driven by 2,000W (peak) Class-D power and uses a direct radiating, ported enclosure. A proprietary, 18-inch, low-frequency transducer with a 4-inch voice coil provides 7mm of driver travel before over-excursion. A variable lowpass filter allows users to customise the crossover transition between the ULT18 and the full range loudspeakers.

All ULT loudspeakers feature Baltic birch enclosures with a powder-coated steel grille, ergonomic handles, a locking IEC power connector, and a defeatable front-panel power-indicator LED. The ULT12 and ULT15 have multi-angle enclosures for use as mains or monitor wedges.
