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.

Source: Select a Source 1–4, Aux, or Aux AGC to edit.
•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.
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.

•Output: Use these settings to determine how
each zone manages its audio output.
oZone Mono/Stereo: Click this menu 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.
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.
