INTRODUCTION The DLM-1 is a remote mic/line input module for use in a Dante network audio system, or other Dante-compatible networks. It is ideal for use with Cloud CDI-CA or CDI-CV Dante input cards, to provide Dante connectivity with Cloud CA Series or CV Series multichannel power amplifiers. MOUNTING - MECHANICAL DLM-1 (UK version) The Cloud DLM-1 fits a standard UK-style dual-gang electrical back box. The box used should have a depth of at least 35 mm.

MIC INPUT – 3-pin XLR3F connector for dynamic microphones. Note that the DLM-1 does not provide phantom power. 2. LINE INPUT (a) – 2 x phono (RCA) sockets for connection of sources such as CD players, audio mixers, radio mic receivers, etc; suitable for line level signals with a nominal level of 0 dBu. 3.

Connect the DLM-1 to a Dante-compliant network here. The connector has two LEDs: • Yellow – ON: data rate of 100 Mb/s in use (auto-negotiated with switch) OFF: data rate of 10 Mb/s in use (auto-negotiated with switch) • Green – illuminates to indicate network activity. Sporadic illumination is normal. 8.

Network switch considerations The installer should ensure that the network switch’s specification makes it suitable for use in a Dante network. If the DLM-1 is being added to an existing Dante network, it is likely that this will be the case. A detailed discussion of network switch specifications for use on a Dante network is beyond the scope of this Installation Guide, but installers needing further information about switch suitability are advised to consult the Audinate support article at https://www.
Configuration The mic and line inputs on the module will be available to the network once the DLM-1 has been routed to a Dante receiver using Dante Controller or equivalent software. If AES67 interoperability mode is enabled and set up for the DLM-1 (through Dante Controller Device Options), then it may alternatively be connected to an AES67-compliant receiver (note that additional configuration procedures may be required).

Local inputs When modules are “daisy-chained” together in this way, the audio signals from each module are summed together to produce a single mono feed to the host unit. Thus two (or more) microphones may be connected within a zone and either or both used as wished, with individual mic level controls at their respective modules. An internal gating circuit on each module automatically “disconnects” any chained modules which are not in use, to minimise noise contribution.
