Aviom DS48 overview

  • 1Description

The DS48 48 x 16 Digital Snake System from Aviom provides digital connectivity for up to 48 inputs and 16 returns between the stage and the FOH (front of house) mix position. A single Cat-5e cable is used for interconnection via the included pair of SB4 System Bridges. Cables can be up to 500' long.

Three AN-16/i-M Mic Input Modules provide the 48 inputs. Each input channel features a three-segment level meter, a continuously variable gain knob, a phase reverse switch, 48V phantom power, and a rumble filter with a roll-off of 85 Hz. Each input module also has a built-in passive splitter allowing the input signals to be sent to additional consoles, recording devices, etc. The AN-16/i v.2 Input Module provides the 16 line-level returns. The four AN-16/o v.4 Output Modules feature 16 balanced DB25 multi-pin connector outputs each. The analog outputs can be set (per channel pair) to +24 dBu, +18 dBu, +4 dBu, or mic level.

The DS48 can be used with nearly any console, and all signals in the system can be split as needed, by connecting additional output modules.

  • SB4 System Bridge

    The SB4 System Bridge from Aviom combines up to 64-channels from four Pro16 or Pro16e A-Net streams onto a single Cat-5 cable, simplifying cabling when using any of the Pro16 series products for personal mixing, digital snakes, or audio distribution systems. All network connections utilize heavy-duty locking Neutrik EtherCon connectors. The SB4 combines up to four 16-channel A-Net streams from digital console cards or analog input modules and transports the data over a single Cat-5 cable. The A-Net Bridge output carries up to 64 channels between the SB4 System Bridge and either another SB4 System Bridge or a D800 A-Net Distributor.

    Additionally, many Pro16 products may be connected to a Pro64 A-Net system with the addition of the ASI A-Net Systems Interface. By separating the 64-channel Pro64 stream into up to four 16-channel Pro16 outputs, the ASI translates the Pro64 A-Net data into Pro16 data. 

    • Four A-Net I/O ports on the rear panel (16 channels each)
    • Neutrik EtherCon connectors
    • One front-panel A-Net Bridge output (up to 64 channels), with EtherCon connector
    • Simplifies the connection of multiple digital console cards to A360 Personal Mixers

  • AN-16/i-M - Microphone Input Module

    The Aviom AN-16/i-M is a rackmount microphone/line input module that allows microphone-level signals to be used with that company's AN-Series Distributed Audio Network products to create digital snakes, for extended personal monitoring and mixing.

    The unit contains 16 high-headroom microphone preamps with 24-bit A-to-D converters. Each channel contains a three-segment level LED meter, a gain control knob, a phase reverse switch, a 48-volt phantom power switch with LED indicator, and a low end filter with an 85 Hz rolloff. Each pair of channels is equipped with a Stereo Link switch, allowing stereo operation when connected to a Pro16 Monitor Mixing System.

    Connectivity includes 16 XLR mic or 1/4" line-level combo inputs, balanced or unbalanced, and the 16 passive mic thru connectors create a built-in microphone splitter. Balanced insert points with separate 1/4" Send and Return jacks allow for standard connection with external outboard processors.

    Two parallel A-Net outputs allow the module to send A-Net data to multiple destinations, allowing for simultaneous patching to a monitor console and a front-of-house console. A separate A-Net Expansion jack allows the unit to be combined with other AN-Series products and to transfer up to 32 channels of audio over a single standard Cat-5 cable, with cable runs of up to 500' between devices.

    Sixteen high-headroom mic preamplifiers, with 24-bit A-to-D converters

    Internal universal power supply for international use, standard IEC connector cable
  • AN-16/o V.4 16-Channel Analog Output Module for Pro16 Digital Snake Network System

    The Aviom AN-16/o V.4 16-Channel Analog Output Module adds an additional 16 output connectors to the Aviom Pro16 series digital network snake systems. This flexible, digital output module features 16 outputs on balanced DB25-pin connectors and switchable output level controls with +24dBu, +18dBu, +4dBu, and mic level switched on each channel.

    Pro16 series audio quality and flexible routing is uncompromised with 24-bit D/A converters and variable sample rates from +/- 44.1kHz to 192kHz. Cat-5e connections seamlessly integrate the AN-16/o V.4 with Aviom's Pro16 Network systems for up to 500 feet, and makes the output module ideally suited for providing additional outputs to FOH consoles, multi-track recorders and other applications.

  • AN-16/i V.2 Input Module

    The AN-16/i v.2 Input Module from Aviom is used to connect up to 16 balanced line-level inputs from a console’s direct outputs, insert points, aux sends, and/or submixes to a personal mixing system or digital snake. When used alone, one AN-16/i v.2 Input Module can generate a single 16-channel Pro16 A-Net signal. The module converts the 16 line-level analog audio channels into uncompressed 24-bit, 48kHz digital audio data.

    The input module includes an A-Net input jack for connecting up to 3 additional Pro16 series input devices. It merges its analog inputs with the incoming A-Net stream, creating the expanded Pro16e digital audio stream utilized by Aviom’s A360 Personal Mixer. The digital audio data is output on standard Cat-5e cables.

    The front panel of the input module has 8 4-position input level/gain sensitivity switches, stereo channel link switches for every channel pair, and per-channel signal present and clip LEDs. Digital network connections on the rear panel include one A-Net in jack and one A-Net out jack.

    The rear panel of the AN-16/i v.2 Input Module also features 16 analog audio inputs with balanced 1/4” TRS jacks. An audio thru jack for each input allows the module to be inserted seamlessly into an existing audio signal path. The input module can be used with any line-level analog audio signal such as console direct outs, inserts, or auxiliary sends.

    The AN-16/i v.2 Input Module works in conjunction with Aviom’s modular Pro16 digital snake and audio distribution system products to support a range of flexible configurations including 16x0, 32x0, 48x0, 64x0, 16x16, 32x16, 32x32, and 48x16. All configurations support an unlimited number of digital splits with no loss in audio quality.
