QM-MD5x1

 

 

QuickMedia™ Matrix Switcher/Mixer

 

Slot 3: Mixer  

The 

MD5x1

 provides one QM input, which contains up to two remote microphone 

channels (MIC A-1 and MIC A-2).  

At the 

MD5x1

 output is a microphone mixer. The microphone mixer can mix MIC  

A-1 and MIC A-2. Before mixing, 4-band equalization can be applied to each mic 
(via the Graphic EQ module on slot 2). In addition, the microphone mixer supports 
NOM (

N

umber of 

O

pen 

M

ics) attenuation for automatic mic gain adjustment. This 

decreases the overall gain of the mic mixer by 3dB for every doubling of the number 
of open microphones feeding the mixer. 

The resulting microphone mix (called “Mic Mix”) is routed to the MIC 1 channel of 
the QM output and to the mixer section of the line level stereo audio output, labeled 
AUDIO OUT.  

AUDIO OUT provides a mixing section. The selected program audio from one of the 
stereo program sources and the “

Mic Mix

” mix described above are inputs to this 

mixer. The mixer mixes the program and the microphone into the three AUDIO 
OUT channels: PRG L, PRG R, and SP. Up to 40 ms delay can be applied to the SP 
channel. 

The Mixer module provides up to five mixer presets, where a mixer preset consists 
of nine mixing values for AUDIO OUT (three mixing levels each for PRG L, PRG R 
and SP). 

The Mixer module also provides up to 16 mic mixer presets, where a mic mixer 
preset consists of two mixing levels (for MIC A-1 and MIC A-2). 

The microphone mix can be mixed into the stereo program and the stereo program 
can be mixed into the speech. After mixing, volume, equalization and tone control 
can be applied (via th

General Audio Controls

 module on slot 5). 

While using the SIMPL Windows programming manager, double-click on 

Slot 3

 of 

the QM-MD5x1 to view the details of the Mixer symbol as shown in the following 
diagram.
