Mixer/Multiplexer Control Panels

Mixer/Multiplexer Control Panel

The Mixer/Multiplexer Control Panel is a window within IQ for Windows that can be used to control any of the set of Crown IQ-compatible mixer/multiplexer products: the MPX-6, the SMX-6 and the AMB-5.
Each of these products has several software controls in common. These include:

L

MPX-6

IM
The MPX-6 is a 6x2 mixer/multiplexer with six mic/line inputs, two main line level outputs and two switchable bus outputs. Under computer control, it can switch the inputs on or off, control their levels, and route them to two main and two bus outputs. Multiple MPX-6s can be connected together to create larger systems.

SMX-6

Y
The SMX-6 is a sensing 6x2 mixer/multiplexer with six mic/line inputs, two main line-level outputs and two switchable bus outputs. It contains a sensing circuit at the beginning of each input to sense the input signal level ahead of any signal processing. Similar sensors are located at each output channel. These sensors, along with its on-board intelligence, enable the SMX-6 to perform many versatile functions like automatic mixing , compression, limiting and automatic level control. In addition an SMX-6 also has all the
manual switching and routing capabilities of an

AMB-5

EL
The AMB-5 is two mixer/multiplexers in one unit. One mixer/multiplexer is an ambient sensing 5x1 mixer/multiplexer. It has all of the capabilities of Channel 1 of an SMX-6 plus the added feature of ambient sensing. Its custom Ambience function enables it to automatically adjust the level of its mix to match the ambient noise level. The second mixer/multiplexer is a basic 6x1 mixer/multiplexer much like Channel 2 of an MPX-6. It offers remote control of Channel 2 from the host computer but it has none of the automatic features like those provided by the Auto functions of Channel 1.

Controls

Standard Controls

Mic/Line Controls

Mic/Line input
Applies To
MPX-6, SMX-6, AMB-5 except where noted
PRELIMINARY
The Mic/Line Input controls the amount of gain from an input channel to each of the two output channels. Each Mic/Line Input can be controlled through the manipulation of a pair of slider controls located at the top of the mixer control panel. The gain of each Mic/Line Input is controlled separately for each output channel. When a gain control is turned down as far as it will go, the input will be turned off for that channel. The range of the input level is -40 to +25 dB in 1/2-dB increments at the top of the scale and ­100 to -40 dB in 5-dB steps at the bottom of the range.
Each Mic/Line Input also includes an input label and two smaller output labels. These labels not only identify the input and output channels of the mic/line input, but can also be used to copy settings from one Mic/Line Input to another.
SMX-6 and AMB-5 only
When the input control is being affected by one or more of the Auto functions available on the SMX-6 or the AMB-5, a second "phantom" input slider may be visible that represents the net input gain at that point. That is, it reflects the input level as affected by any of the Auto gates, limiters, compressors, etc., and their relation to the Max Gain setting.
Net input gain
Applies To
SMX-6, AMB-5
The net gain of an input is the amount of gain that is applied from an input channel to one of the output channels after the application of all enabled Auto functions. The net gain of each input is displayed along with the mic/line input gain on the control panel. If the Auto functions of the mixer are turned off, then the net gain is equal to the mic/line input gain. If, however, Auto is turned on then the net gain can be expected to differ from the mic/line input gain. When this is the case, the net gain will be displayed as a "phantom" fader for any input/output channel where it differs from the mic/line input gain. The net gain slider may move actively, showing the operation of the various Auto functions. The reason that this is called the "net" gain is because the gain settings may be the result of several Auto functions working together.
Input Level
Applies To
SMX-6, AMB-5
The peak input level of each audio input is represented by a moving bar graph in the center of the mic/line input.

Input Label
Applies To
MPX-6, SMX-6, AMB-5
The input labels number both the mic/line inputs of all of the IQ mixer products and the expanded input sections of the SMX-6 and the AMB-5. You can use this label to copy the settings of one input channel to another channel. This is accomplished by "drag-and-drop:"
1) Click on the label of the input whose settings you wish to copy.
PRELIMINARY
2) While holding the mouse down, drag the cursor over the input section that you want to receive the copied settings.
3) Release the mouse button.
Note that in the case of the SMX-6 and the AMB-5, the settings copied are only function designated by the
and not all of the settings.
Output Label
Applies To
MPX-6, SMX-6, AMB-5
The output labels number input sliders as belonging to the outputs, 1 or 2, of the mixer. The mic/line inputs of all of the IQ mixer products and the Auto Control Pages of the SMX-6 include these labels. The input designation 1 through 6 and the output designation 1 or 2 combine to give you a single input/output channel (e.g. input 4 / output 2). You can use these labels to copy all of the settings of one input/output channel to any other input/output channel. This is accomplished by "drag-and-drop:"
1) Click on the output label of the input/output channel whose settings you wish to copy.
2) While holding the mouse down, drag the cursor over the input/output section that you want to receive
the copied settings.
3) Release the mouse button.
Note that in the case of the SMX-6 and the AMB-5 the settings copied are only function designated by the
those related to the Auto
Auto Control Page
those related to the Auto
Auto Control Page
and not all of the settings.
Note: If you drag the settings of one input/output channel over the input label, then both outputs of that input channel will be affected.

Data LED

Applies To
MPX-6, SMX-6, AMB-5
Every IQ mixer component is equipped with a data light that normally flashes only during those moments when performing serial communications. This button will allow you to set it so the "Data" LED is fixed on.
