1.7 Rack Connections with MADI

Connect Console MADI BNC OUT socket to Rack BNC IN AUX socket.

 

 

 

Sharing Racks with MADI 

If the system is running at a sample rate of 48KHz a D2-Rack, SD-Rack, SD-MINIRack or MQ Rack can be shared 
between 2 consoles (Two QUANTUM 2s or a QUANTUM 2 and another Quantum or SD-Series console) with 
the connection system shown below. 

In this setup:

 

1) All inputs can be shared by the two consoles but only one console controls the rack analogue gains (the 
"Master" console) 

2) The console which is not controlling the gains (the "Slave" console) can automatically adjust its digital trims 
to compensate for the gain changes using a system known as "Gain Tracking" (see below) 

3) Only the "Master" console can use the outputs of the shared rack 

The recommended connection between the Monitor (Slave) console and Stage Rack is a single MADI OUT from 
the Shared Rack's AUX MADI connected to the console's MADI A IN 

The FOH (Master console) is connected via MADI A IN and OUT to the stage rack. 

A similar method can be used if the Monitor console requires gain control and the FOH console will track the 
gain changes. 

MADI OUT from the Shared Rack's AUX MADI connected to the FOH console's MADI A IN. 

The Monitor (Master console) is connected via MADI A IN and OUT to the stage rack. 

Note: The "Master" console should be set to provide "Master Sync" (Setup>Audio Sync menu - see 
diagram below) to the Shared rack 

The "Slave" console should be set to receive its Audio Sync from the MADI slot that is connected to the 
Shared Rack. 

1) The operators should agree on and set a level of analogue gain that provides enough headroom for the 
required application. 

2) The second console should connect to the Shared rack in 

Receive Only 

mode (only MADI Input cable 

connected) 

3) 

Gain Tracking

 (the 

GT ON/OFF

 button at the top of the Input channel setup view) can be switched on for 

the console that is in "

Receive Only"

 mode for all the channels that are being shared. 

4) When an analogue gain control is changed on the "Master" console, the "Slave" console's analogue gain 
should reflect the changes and the digital trim control should compensate for this change by moving by the 
same amount in the opposite direction. 

IMPORTANT Note: If Gain Tracking is active on a channel, the digital trim control will still respond to the 
local gain adjustment by compensating locally for the displayed gain change. 

If the "Slave" console loads a session where the Analogue Gain and +48V settings do not match the 
current state of the racks, the Master console should then reload its session to update the state of these 
controls on the "Slave" console
