Synchronizing MADI Devices
Any time two digital audio devices are connected together
care must be taken to ensure they are properly synchronized
or the audio will suffer from clicks, pops and distortion (even
if the devices are operating at the same sample rate).
This synchronization can be achieved by using a dedicated
word clock connection between devices, by synchronizing the
receiving device to the incoming MADI audio signal, or by using onboard Sample Rate Conversion (SRC) on the receiving
device.
This section shows the following three example of configurations using a dedicated word clock connection between devices:

Using Word Clock to Synchronize Two VENUE Systems
 Using Word Clock to Synchronize a VENUE System and another MADI Device

Using an External Master Clock to Synchronize Devices
When connecting two VENUE systems using MADI, a dedicated word clock connection is required.
Not all devices support all of these synchronization methods,
so you should consult the user guide for your MADI device in
order to determine its capabilities.
10 VENUE MADI Option Card Guide
Clocking setup between two VENUE systems
To synchronize two VENUE systems:
 Connect the coaxial cable from the Word Clock Out port on
one of the VENUE systems to the Word Clock In port on the
other VENUE system. The VENUE system receiving word clock
auto-detects word clock and displays “EXT” in the Mode box
on-screen.

VENUE system can send or receive word clock.
When using MADI to connect your VENUE system to an external MADI device, you may want to use an external master
clock to provide word clock to both your VENUE system and
the external MADI device. All devices except the VENUE system must be set to a 48kHz word clock rate.

Using MADI
You can use MADI with your VENUE system in the following
ways:
Stage mode Your Stage inputs are the main source of audio
signals for your VENUE system. In this mode, you can send a
one-for-one digital split of VENUE Stage input channels to an
external MADI device such as a MADI router, another digital
mixing console, or a digital recorder. See “Sending A Direct
Digital Split of Stage Inputs” on page 12.
Virtual Soundcheck mode You can soundcheck the band using
pre-recorded audio from an external MADI device. Changes
made in Virtual Soundcheck mode, including Snapshot creation and modification, carry over when switching back to
Stage mode. Input channel gain changes made while in Virtual Soundcheck mode can be applied to Stage input channels
when switching back to Stage mode. See “Performing a Virtual
Soundcheck” on page 13.
MADI Input mode Audio from your MADI device is the main
audio source for your VENUE system. Stage inputs 1-48 on
your VENUE system are replaced with inputs from an external
MADI device such as another VENUE system or another digital mixing console. Input channel gain and other PRE parameters such HPFs can be stored in Snaphots. See “Replacing
Stage Inputs with MADI Inputs” on page 14.
In all modes, MADI assignable inputs and outputs are available. Using assignables, you can send the Main L/R Mix or a
submix (Matrix, Group, etc.), send the Direct Outs of VENUE
system channels, and route audio from your MADI device to
any available VENUE system input channel. See “Using MADI
Assignable Channels” on page 15.
Sending A Direct Digital Split of
Stage Inputs
When Stage inputs are the main source of audio for your
VENUE system, a one-for-one digital split of Stage input channels 1-48 (even unused Stage input channels) are sent to both
the optical and coaxial outputs of the MADI card.
The pickoff point for each channel is post-analog input gain,
but pre-digital trim and all channel processing, including high
pass filter. Thus, the gain for any input channel sent to your
external MADI device is dependent on the VENUE system input gain setting of that Stage input channel.
VENUE systems use a combination of analog input gain
and digital trim, controlled by a single Gain control, to set
the overall input channel gain. Stage Input channels 1-48
sent via MADI are sourced post-analog input gain, but
pre-digital trim, which means the signal level received by a
connected MADI device is affected by the analog input gain
only. This gain is adjusted in coarse 3 dB steps (for
VENUE FOH Rack) or 6 dB steps (for VENUE Mix Rack),
and a slight click may be heard on the receiving MADI device when a Stage Input channel’s Gain control is adjusted.
MADI assignable input and output channels 49-64 (or
49-56 for 56-channel MADI devices) can be used independently of the Stage input splits. See “Using MADI Assignable Channels” on page 15 for more information.
To send a split of the Stage inputs:

Performing a Virtual Soundcheck
In Virtual Soundcheck mode, audio from your external MADI
devices replaces the corresponding Stage inputs one-for-one,
and appear in place of those Stage Inputs in the D-Show software Patchbay. All changes (such as channel assignments, and
input and output processing) are carried over when you
switch to Virtual Soundcheck mode, and the digital portion of
the gain for each channel is preserved and applied to the incoming MADI signal. This results in the same apparent levels
for both the MADI inputs and the Stage inputs.
To perform a Virtual Soundcheck:
1 Do one of the following to put your system into Config
Mode:
• Press the Console Config switch on the console.
– or –
• In the Inputs section of the System Configuration page,
beneath Inputs 49–96, select MADI 2, then select
Virtual Soundcheck from the MADI Format pop-up menu.

5 Click Apply. The MADI inputs are now active.
The Stage tabs in the Patchbay are replaced by MADI tabs, and
all Stage routing is preserved.
If you change input routing when MADI inputs are active,
those changes remain when you switch back to Stage input mode.
• Double-click the Mode box in the bottom-right corner of
the screen.

Gain Settings in Virtual Soundcheck Mode
VENUE systems use a hybrid analog/digital gain approach for
analog Stage inputs. The behavior of gain settings when
changing between modes is explained below.
• Apply the gain change, yielding a Stage Rack gain increase of 6 dB, or a final setting of +36 dB (30+6).
– or –
• Discard the gain change, leaving the original Stage input
gain unchanged at +30 dB.
Stage Mode to Virtual Soundcheck Mode
When switching from Stage mode to MADI Virtual Soundcheck mode, the digital component of the gain stage (up to
+3 dB for the FOH Rack, and up to +6dB for the Mix Rack) is
preserved, so MADI audio signals and Stage inputs have the
same apparent level.
Virtual Soundcheck Mode to Stage Mode
If you change the digital gain of any channel from your
VENUE console while in Virtual Soundcheck mode, you have
the option of keeping or discarding those gain changes when
you switch back to Stage mode.
D-Show will automatically activate or deactivate the Pad on a
channel to compensate for large gain changes.
Gain compensation is applied to all applicable channels. It
is not possible to preserve gain for an individual channel or
individual MADI card.
To keep or discard gain changes made in MADI Virtual
Soundcheck mode, click one of the following:
Apply Any gain changes made in Virtual Soundcheck mode are
added to the total Stage input gain on each channel.
Discard Any gain changes made in Virtual Soundcheck mode
are lost and the Stage input gain is returned to its previous
value on each channel.
Snapshot PRE Settings and Virtual
Soundcheck Mode
The PRE Data Type Scope button on the Snapshots page lets
you recall the preamplifier settings on inputs for all scoped Input Channels. Go to the Options > Snapshots page to set the
PRE parameters to be recalled by the PRE data type button.

Replacing Stage Inputs with MADI
Inputs
In MADI Input mode, an external MADI device is the main
source of audio signals for your VENUE system. Audio channels from your external MADI device appear one-for-one in
place of Stage inputs in the D-Show software Patchbay.
To replace Stage inputs with MADI inputs:
Gain change dialog
For example, if you set the Stage Rack gain for a channel to
+30 dB, then switch to MADI Virtual Soundcheck inputs, a
digital gain of +2.2 dB is preserved in Virtual Soundcheck
mode to yield the same overall gain on that channel (because
2.2 dB of the 30 dB setting was digital gain as compared to analog gain).
While in Virtual Soundcheck mode, if you increase the digital
gain on a channel by 6 dB (to a displayed setting of +8.2 dB),
and then switch back to Stage mode, you can do one of the
following:

Adjusting Input Gain in MADI Input Mode
In MADI Input mode, input channel gain is adjusted using the
input gain encoders. Digital gain (-20 dB to +18 dB) is available for all MADI inputs.
When switching from Stage mode to MADI input mode, all
gains for MADI input channels are set to 0 dB.
If you are using a 56-channel format MADI device, a total of
eight assignable inputs and eight assignable outputs are available simultaneously. These channels are numbered 49-56 in
the Patchbay.
Using assignables, you can do the following:
Send Direct Outs Send Direct outs of individual input or output channels, with adjustable level and selectable pickoff
point.
Send a Stereo Left/Right Mix Send a stereo Left/Right mix, or
