DLM-1 Series Installation Guide V1.0 3
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 ampliers.
NOTE: Unless specically stated otherwise, all references
to “DLM-1” in this Installation Guide can be taken to apply
to all DLM-1 mechanical and cosmetic variants.
The DLM-1 module combines the functions of a remote input
connection plate, local audio mixer and mic-over-music
priority with a Dante (AES67-compatible) output.
Two inputs - for a microphone and a stereo line signal
(typically for a local music source) - are provided, with
individual level controls. The line inputs are available both as
a pair of phono sockets (RCA jacks) and a 3.5 mm jack socket.
The stereo line input is summed to mono, and then mixed
with the mic input.
The microphone signal path includes a limiter (always active)
and a switchable 120 Hz hi-pass lter to help minimise breath
and handling noise. Both mic and line inputs incorporate gate
circuitry to reduce extraneous noise from connected sources
when they are not in use.
The DLM-1 is connected to the Dante network using a single
Cat 5 Ethernet cable and RJ45 connector. The module is
powered via PoE (Power-over-Ethernet). The module includes
Dante receiver capability, which permits additional DLM-1s
to be “linked” together so that multiple input points can be
installed in the same zone or area. The linking is congured
using Dante Controller software.
MOUNTING - MECHANICAL

1. 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. LINE INPUT (b) – 3-pole 3.5 mm jack socket for connection of sources such as computers, laptops and digital media
players; suitable for line level signals with a nominal level of -10 dBV.
NOTE: Stereo line inputs [2] and [3] are summed together, and also summed to mono. If using a mono source (e.g., a radio mic
receiver) we recommend that its output is connected to both L and R inputs using an adaptor or suitably wired cable: this will
avoid unwanted signal attenuation.
4. MIC LEVEL – gain control for mic input. Up to 40 dB gain is available; with the control fully anti-clockwise, the input is
effectively ‘off’
5. MUSIC LEVEL – level control for whichever line input ([2] or [3]) is in use. Adjust to suit the level from the source device
in use.
6. MIC PRIORITY – default function for this button is to give the microphone input priority over the line input(s). See
“DLM-1 Priority Operation” on page 10

Network switch considerations
The installer should ensure that the network switch’s specication 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 specications 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.audinate.com/support/networks-and-switches,
and in particular, the two sections in the article headed:
• “What is the minimum requirement for switches in a Dante network?”, and
• “What features are important when purchasing a switch?”
See also the following section regarding Power-over-Ethernet.
Power considerations
The DLM-1 is powered using PoE. In most installations, the DLM-1 will be connected to a network switch, and thus this switch
should ideally be PoE-capable. PoE should be enabled for the port in use (if per-port power activation is an option).
The DLM-1’s power consumption is less than the 3.84 W rating applicable to Class 1 PoE, so Class 1-rated ports should cause
no issues.
If a PoE-enabled switch is unavailable, a Class 1 PoE injector may be employed. These are readily available from trade suppliers
at low cost and will generally be supplied with a separate mains power supply unit. The injector should be rated for 100Mb/s
use. It can be installed “in-line” at any convenient point; its location will generally be dictated by the availability of AC power.

Conguration
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 conguration procedures may be required).
The relative volume of the mic and line sources will be determined by the module’s level controls.
The Dante Controller screengrab below shows a single DLM-1 (the transmitter) and a Cloud CDI-CA4 Dante input card (the
receiver). In a real-world Dante network, there will be many more transmitters and receivers. Note that any Dante-compliant
device (amplier, mixer, etc.) may act as the receiver.
In this example, Channel 1 of the DLM-1 is routed to Input 1 of the CDI-CA4 card. On the DLM-1, Channel 1 is idented in the
software as 01 Mix Mono / Mix L / Line Mono. The DLM-1’s Channel 1 output is a mono mix of all the module’s
inputs: use only Channel 1 for routing.
Connecting multiple DLM-1s
Two or more DLM-1s may be installed in the same audio system Zone. This enables microphones and music sources to be
connected at different locations within a single Zone (typically one of large area or complex layout).
The “interconnection” of multiple DLM-1s is achieved using Dante Controller. The DLM-1 is a Dante receiver as well as a
transmitter, and the output of one DLM-1 may be routed to the input of another. The receiving DLM-1 will mix the mono audio
from the rst module with its own inputs, and make a composite mix of all audio sources available to the network.
Each DLM-1 should be connected independently to the network switch serving the area (using a PoE injector for each if
necessary).

The Dante screengrab below shows two DLM-1s, with a CDI-CA4 card as the nal audio destination. The output of the rst
DLM-1 (idented DLM-1-1) is routed to the input of the second DLM-1 (idented DLM-1-2). The output of the second DLM-1
is then routed to Input 1 of the CDI-CA4 card.
This principle of “virtual daisy-chaining” may be continued for as many modules as needed. Note that only Channel 1 of each
DLM-1 is used in all cases.

DLM-1 Series Installation Guide V1.0

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. This also applies to multiple music sources simultaneously connected (though the possibility of resulting
cacophony makes this a less likely scenario!)
DLM-1 PRIORITY OPERATION
If the MIC PRIORITY button on the DLM-1 faceplate is not pressed, mic and/or line signals connected at the module will
be routed, and heard through the audio system at volumes which can be controlled from the MIC LEVEL and MUSIC LEVEL
controls on the faceplate.
The DLM-1’s Priority facility operates as follows: with MIC PRIORITY pressed, a signal present at the mic input, post the
microphone input level control, will cause the line input signal connected at the same module to “duck” by 30 dB, giving the
microphone priority over the music. The attack time (how quickly the music level drops when the mic is used) and release time
(how quickly it recovers after the mic signal stops) are pre-set, and optimised for best audible results.
NOTE: When using microphone and/or music sources simultaneously from multiple linked modules, Priority mode will give
each module’s microphone input priority over all other audio inputs, both via its local mic-over-music action and its link to
other modules. A module’s position in the linked chain will therefore determine which other modules it has priority over. It
is recommended that the Priority function is not used if this position-dependent behaviour may produce unwanted ducking
effects.
