Description

The ASL Enchorus system comprises four I/O interfaces for use with a Dante multichannel digital audio network. Dante is a well-established, robust and scalable networking protocol which uses Layer-3 IP technology to transport up to 512 channels of audio bidirectionally at 48 kHz sample rate via standard Ethernet connections.

Enchorus interfaces act as break-in/break-out boxes, allowing individual Dante channels to be accessed at any convenient location, either as inputs or outputs. They are ideal for use in large-scale fixed or touring live sound systems, but are equally suitable for studio use. Each of the four interfaces comprising the range provides up to eight inputs and/or outputs in either analogue or AES3 digital format (each AES3 input or output being able to carry two audio channels).

The interfaces are ideal for use as stage boxes for mic connection (ENC 1201), but also for audio acquisition and distribution anywhere in the system. The on-board DSP allows the creation of multiple custom mixes for the performers comprising live audio sources and/or recorded sounds at will. The interfaces would also be an excellent choice for generating multiple, custom cue mixes for pit musicians in large-scale musical productions. The ENC 1102 is particularly useful for use as an I/O interface to outboard processing equipment at the FOH or monitor positions.

All models in the range have the same complement of connectors for audio I/O: eight XLRs on the front panel and a single RJ45 on the rear panel (plus two further RJ45s for Dante connection). The I/O complement of the four models is summarised in the table below:

Model XLR I/O RJ45 I/O
ENC 1201 8 x mic inputs 4 x analogue line outputs (bal.)
ENC 1202 8 x analogue line inputs (bal.) 4 x analogue line inputs (bal.)
ENC 1101 8 x AES3 outputs (16 chs) 4 x AES3 inputs (8 chs)
ENC 1102 4 x AES3 inputs (8 chs)
4 x AES3 outputs (8 chs)
2 x AES3 inputs (4 chs)
2 x AES3 outputs (4 chs)

All models have a powerful on-board DSP section, consisting of an audio routing matrix, eight 16/2 mixers, plus filtering and EQ sections for each input and output. Additionally, the ENC 1201 includes a four-way mic splitter, with each feed being independently controllable in terms of gain, phase and routing.

Audinate’s Dante Controller application is used to define the subset of Dante channels to be available to the internal matrix, both as inputs and outputs. The inputs to the matrix are then the physical inputs, the selected Dante channels, and the 16 (8 x 2) outputs of the mixer section. The outputs from the matrix feed the 16 inputs to the mixer section, the physical outputs, and the selected Dante channels. The matrix is configured by a series of web browser pages, such that a physical output may be a single Dante channel, a mix of Dante channels, or a mix of Dante channels and the interface’s physical inputs. This opens up the possibility of precisely configuring foldback for individual performers on a repeatable basis. Similarly, input channels can be freely mapped onto Dante channels so that they appear in the order required on the faders of a suitably equipped mixing console.

Every physical input and output has 4-band parametric EQ and flexible filtering available to it, controlled through the web interface. The mic inputs on the ENC 1201 have additional functions: mic gain, phase reverse, phantom power and a four-way splitter, all outputs of which are available to the matrix for onward routing.

Complete system setups, including Dante channel selection and all interface parameters, may be exported, stored and rapidly imported, allowing complete reconfiguration in milliseconds. Individual inputs and outputs can also be named.

Physically, the interfaces are 1U, half-rack width fitted with substantial rubber buffers to allow them to be used on-stage, and may be stacked if wished. If preferred, the buffers may be removed to allow rack mounting. A rack kit to mount two units is available as an accessory. Enchorus interfaces are self-powered, with dual internal Universal PSUs (100 to 240 V AC) and separate AC inlets. The Dante network connects via dual Neutrik Etherconn LAN ports: this allows primary and secondary network connections, permitting fully redundant operation.
