Setup
Items not listed under Introduction > Box Contents are sold separately.
To set up DN-508MXA 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 the included 5-pin Euroblock with jumper wires to connect Line Outputs 1–4 to Amp Inputs 1–4.
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. Use standard Euroblock connectors to connect the loudspeakers of your different zones to the
Speaker Outputs on the rear panel. For LoZ speakers at 4 Ohm or 8 Ohm, each group of 2
connections corresponds to 1 zone, for 4 total output zones. For HiZ speakers at 70 V, 100 V, or BTL,
each pair of groups of 2 connections corresponds to 1 zone, for 2 total zones. Each zone has a positive
(+) and negative (-) connector. Always make sure to properly align the wiring polarities between your
speakers and DN-508MXA.
5. To manage DN-508MXA 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-508MXA to that router. Alternatively, connect DN-508MXA’s Ethernet Port
directly to a computer using an Ethernet crossover cable.
6. To manage DN-508MXA 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-508MXA. 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-508MXA rather than serial communication. It
is much easier to use the web interface via IP communication than a third-party utility via RS-232 serial
communication.
7. Use the included power cable to connect DN-508MXA to a power outlet.
8. Power on all of your audio sources (Blu-ray®players, stereos, microphones, amplifiers, etc.).

•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.
oAttack Time: Select this to set how long it takes for the current signal to be fully attenuated.

9
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.
Amp: Select this to edit the Amp Inputs 1–4. Once selected, you can set Hi Impedance Mode (70V
mode, 100V mode, or Off), Hi Pass Filter (On or Off), BTL (On or Off), and Impedance Mode (4 ohm
or 8 ohm).
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-508MXA 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-508MXA will display this at the top of the web interface and will use it for scheduling.
You can also set DN-508MXA 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

same output settings.
oPriority 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.
Volume: Click this menu to set the volume
level of the incoming audio signal.
Source: Click this menu 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.
Threshold: Click this menu 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.
Attack Time: Click this menu to set how
long it takes for the current signal to be fully
attenuated.
Hold Time: Click this menu to set how long
the current signal remains fully attenuated after the incoming audio falls below the threshold.
Release: Click this menu 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.
Attenuation Level: Click this menu to set how much the current signal’s volume is attenuated
(“ducked”).
oDelay: Click this menu 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.
oDynamics: These settings determine the dynamic control (via compression) of the zone’s output
signal.
On/Off: Click this menu to enable (On) or disable (Off) the zone’s dynamic control.
Threshold: Click this menu to set the threshold. The incoming audio signal must be louder than
this threshold to trigger the dynamic control.
Ratio: Click this menu to set the ratio of the dynamic control—how much the signal is
attenuated relative to its original level.
Attack Time: Click this menu to set how long it takes for the dynamic control to compress the
signal.
Release: Click this menu 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.
Gain: Click this menu to set how much gain is applied after the signal is compressed.
Knee: Click this menu 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.

Instalación
Los elementos que no se enumeran en Introducción > Contenido de la caja se venden por separado.
Cómo instalar DN-508MXA 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 el Euroblock de 5 patillas con cables de puente incluido para conectar las salidas de línea 1–4 a
las entradas de amplificador 1–4. 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. Utilice conectores Euroblock estándar para conectar los altavoces de sus diferentes zonas a las salidas
para altavoces del panel trasero. Para altavoces de LoZ a 4 u 8 ohmios, cada grupo de 2 conexiones
corresponde a 1 zona, con un total de 4 zonas de salida. Para altavoces de HiZ a 70 V y 100 V o BTL,
cada grupo de 2 conexiones corresponde a 1 zona, con un total de 2 zonas. Cada zona tiene un
conector positivo (+) y uno negativo (-). Asegúrese siempre de alinear correctamente las polaridades del
cableado entre sus altavoces y el DN-508MXA.
5. Para administrar el DN-508MXA 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-508MXA a ese enrutador. Como
alternativa, conecte el puerto Ethernet del DN-508MXA directamente a un ordenador mediante un cable
Ethernet cruzado.
6. Para administrar el DN-508MXA 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-508MXA. 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-508MXA 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-232 en serie.
7. Utilice el cable de corriente incluido para conectar el DN-508MXA a una toma de corriente.
8. Encienda todas sus fuentes de audio (reproductores de Blu-ray®, estéreos, micrófonos, amplificadores,
etc.).
9. Encienda el DN-508MXA.
