Setup
Items not listed under Introduction > Box Contents are sold separately.
To set up DN-508MX with your sound system:
1. If you are using any audio source with RCA outputs (Blu-ray®players, stereos, etc.), use
standard RCA cables to connect them to the ST inputs on the rear panel. Your audio sources
must be line-level (no phono-level turntables).
2. If you are using an amplifier or other audio source with outputs that can be wired into standard
Euroblock connectors, connect them to the mic/line inputs on the rear panel.
3. Use standard Euroblock connectors to connect the loudspeakers of your different zones to the
line outputs on the rear panel. Each group of 5 connections corresponds to 2 zones. Each zone
has a hot (H) and cold (C) connector, and each pair of zones shares the ground (G) connector.
4. To manage DN-508MX using its web interface, connect the Ethernet port and your computer
to a network switch or router using standard Ethernet cables. If your computer is wirelessly
connected to your router, connect just DN-508MX to that router. Alternatively, connect DN-
508MX’s Ethernet port directly to a computer using an Ethernet crossover cable.
5. To manage DN-508MX using serial communication, connect the remote port to your
computer using a 9-pin D-Sub cable. Use a third-party utility to manage DN-508MX.
Alternatively, connect the RS-422 port to a third-party utility using a standard analog telephone
cable with RJ45 connectors.
Tip: We recommend using the web interface to control DN-508MX rather than serial
communication. It is much easier to use the web interface via IP communication than a third-
party utility via RS-232C or RS-422 serial communication.
6. Use the included power cable to connect DN-508MX to a power outlet.
7. Power on all of your audio sources (Blu-Ray®players, stereos, microphones, amplifiers, etc.).
8. Power on DN-508MX.

•Name: Select this to edit the display name of the Source up to 32 characters.
•Gain: Select this to set the gain trim level of each audio source.
•Aux AGC: These settings control the automatic gain control (AGC), which adjusts the gain level
to help reduce noise in the signal.
oCompensation Level: Select this to set how much gain is applied after the signal is
compressed by the AGC.
oResponse Time: Select this to set how quickly the AGC reacts to audio signal.
oNoise Gate: Select this to enable (On) or disable (Off) the noise gate. When on, the audio
signal will be automatically muted if it is below a certain volume level. This eliminates
moments during which the source is not producing any sound but there is still detectable
noise in the audio signal.
Output: Select a Zone 1–8 to edit.
•Name: Select this to edit the display name of the Zone Output up to 32 characters.
•Mono/Stereo: Select this to set whether the audio signal the zone plays is monaural (Mono) or
binaural (Stereo). When set to Stereo it will actually use 2 zones (e.g., Zones 1–2, Zones 3–4),
which will share the same output settings.
Note: When using a Stereo output, editing the first zone will apply changes to both zones. The
second zone will show as unavailable for editing.
•Priority Settings: Each zone has settings for 1st priority and 2nd priority. When the mic/line
input (set in the Source menu) detects an incoming audio signal, any other signal sent to that
zone will be attenuated (“ducked”) so the incoming signal can be heard. The 1st-priority source
will attenuate the 2nd-priority source.
oVolume: Select this to set the volume level of the incoming audio signal.
oSource: Select this to set the source for the priority: Mic/Line 1–6or no source (None).
Setting both priorities to the same mic/line input will result in greater-than-normal
attenuation.
oThreshold: Select this to set the threshold. The incoming audio signal must be louder than
this threshold to attenuate the current signal. A lower threshold produces more attenuation.

9
oAttack Time: Select this to set how long it takes for the current signal to be fully attenuated.
oHold Time: Select this to set how long the current signal remains fully attenuated after the
incoming audio falls below the threshold.
oRelease: Select this to set how long it takes from the fully attenuated signal to return to its
previous level after the incoming audio signal falls below the threshold.
oAttenuation Level: Select this to set how much the current signal’s volume is attenuated
(“ducked”).
•Delay: Select this to set how long it takes for the zone to play any incoming audio signal after it
receives it. This is useful when multiple zones are playing the same audio signal—listeners in
certain areas may hear that same signal multiple times because the sound from each zone
reaches them at different times rather than all at once. Delaying the zone’s audio output can
help prevent this effect.
•Dynamics: These settings determine the dynamic control (via compression) of the zone’s
output signal.
oOn/Off: Select this to enable (On) or disable (Off) the zone’s dynamic control.
oThreshold: Select this to set the threshold. The incoming audio signal must be louder than
this threshold to trigger the dynamic control.
oRatio: Select this to set the ratio of the dynamic control—how much the signal is attenuated
relative to its original level.
oAttack Time: Select this to set how long it takes for the dynamic control to compress the
signal.
oRelease: Select this to set how long it takes from the compressed signal to return to its
original level after the incoming audio signal falls below the threshold.
oGain: Select this to set how much gain is applied after the signal is compressed.
oKnee: Select this to set the knee of the dynamic control. This determines how sharp or
smooth the “curve” is when compression is applied at the threshold. A “hard” knee
produces very dramatic compression, while a “soft” knee produces a more natural-sounding
compression.
Mute: Select this to mute either the music only (Music) or all audio signals (All).
Ethernet: Select this to configure your Ethernet settings. Select IP Address, Subnet Mask, Gateway, or
IP Control Port to configure DN-508MX to detect network settings automatically (Auto On/Off), or enter
settings manually using the Volume/Sel knob.
Baudrate: Select this to set the baud rate of each port. RS232C is for the remote port. RS422 is for
the RS-422 port. Each rate is shown bits per second (BPS).
Time: Select this to edit the System Time and set the current month, day, year, hour, minute, and
second. DN-508MX will display this at the top of the web interface and will use it for scheduling.
You can also set DN-508MX to enable (On) or disable (Off) daylight saving time. When on, select
each menu below it to set the month, day, and hour that daylight saving will start and end. Choose

Instalación
Los elementos que no se enumeran en Introducción > Contenido de la caja se venden por separado.
Cómo instalar DN-508MX con su sistema de sonido:
1. Si está utilizando una fuente de audio con salidas RCA (reproductores de Blu-ray®, estéreos,
etc.), utilice cables RCA estándar para conectarlos a las entradas ST del panel trasero. Sus
fuentes de audio deben ser de nivel de línea (no giradiscos de nivel fonográfico).
2. Si está utilizando un amplificador u otra fuente de audio con salidas que pueden cablearse a los
conectores Euroblock estándar, conéctelas a las entradas de micrófono/línea del panel trasero.
3. Utilice conectores Euroblock estándar para conectar los altavoces de sus diferentes zonas a las
salidas de línea del panel trasero. Cada grupo de 5 conexiones corresponde a 2 zonas. Cada
zona tiene un conector caliente (H) y un conector frío (C), y cada par de zonas comparte el
conector a tierra (G).
4. Para administrar el DN-508MX a través de su interfaz web, conecte el puerto Ethernet y su
ordenador a un conmutador o enrutador de red utilizando cables Ethernet estándar. Si su
ordenador se conecta a su enrutador de forma inalámbrica, conecte solamente el DN-508MX a
ese enrutador. Como alternativa, conecte el puerto Ethernet del DN-508MX directamente a un
ordenador mediante un cable Ethernet cruzado.
5. Para administrar el DN-508MX a través de la comunicación en serie, conecte el puerto
remoto a su ordenador utilizando un cable D-Sub de 9 patillas. Utilice una utilidad de terceros
para administrar el DN-508MX. Como alternativa, conecte el puerto RS-422 a una utilidad de
terceros utilizando un cable de teléfono analógico estándar con conectores RJ45
Consejo: Recomendamos utilizar la interfaz web para controlar el DN-508MX en lugar de la
comunicación en serie. Es mucho más fácil utilizar la interfaz web a través de la comunicación IP
que una herramienta de terceros a través de la comunicación RS-232C en serie.
6. Utilice el cable de corriente incluido para conectar el NDN-508M a una toma de corriente.
7. Encienda todas sus fuentes de audio (reproductores de Blu-ray®, estéreos, micrófonos,
amplificadores, etc.).
8. Encienda el DN-508MX.
