markets. The ASP-MG24 features the latest in available technology utilizing 32-bit (40-bit extended) floating point processors and high performance

24-bit analog converters. Both balanced inputs are mic / line selectable with rear panel mounted trim adjustments, along with 4 independent masking

generator input sources. Inputs and outputs can be routed or mixed in multiple configurations to meet even the most complex system designs.

Control parameters include I/O levels, delay, polarity, parametric EQ, crossover selections, 31 band EQ, white / pink noise, auto ramp, routing, mixing

and compressor / limiters. The ASP-MG24 can be controlled or configured in real time with the intuitive PC GUI, accessed via the RS-232 or USB

interface. Software upgrade for CPU and DSP via PC always keeps the ASP-MG24 current.

Key Features

• 2 Mic / Line Inputs and 4 Outputs

• Rear Mounted Input Trim Adjustments

1. Power Supply Socket

An external UL rated 120V AC power supply has been included with the ASP-MG24. Only use the provided power supply due to the specific DC

voltages required to operate the unit.

2. Input Connectors

There are two removable 3 Pin Phoenix type connectors for providing input signal to the unit. They can accept either a balanced or unbalanced signal.

For balanced signals connect ground to (GND), positive signal to (+) and negative signal to (–). For unbalanced signals connect the (–) to the (GND) and

the positive signal to (+).

3. Mic / Line Level Selection

Each input has the capability to accept either a microphone or line level signal. Prior to connecting the inputs make sure the software input gain that

applies to the channel routing is set to -10dB, and the limiters are set to +20dB for gain setup. Prior to applying signal to the input, set the analog gain

switch to match the type of input being used. The Line position gain is calibrated for 0dBu or unity gain within the DSP software. The Mic position gain

is calibrated for -30dBu when the DSP gain is set for unity or 0dB. If more gain is needed, carefully increase the appropriate channel DSP gain in the

software. If using a microphone, it is recommended to start with the input gain set to -40dB and slowly increase the input gain to the desired level.

4. Output Connectors

There are four removable 3 Pin Phoenix type connectors for providing output signal. They can deliver either a balanced or unbalanced signal. For

balanced signals connect ground to (GND), positive signal to (+) and negative signal to (–). For unbalanced signals connect the (–) to the (GND) and the

positive signal to (+).

5. RJ45 Port

This port allows remote configuration of the GUI via a LAN connection. A fixed IP address is needed to access the control software. Note: This port is

only active with the ASP-MG24TDB.

6. Input Gain Trim Pots

Channel 1 & 2 input gain pots have an adjustment range of +6dB to -40dB. The center of pot travel is 0 gain or cut.

Getting to Know the Software

Loading the Software

1. Load the software onto the computer by following the Quick Start Guide and Software Installation Guide.

2. Note: It is important to have the computer screen resolution set to the highest viewing setting or a minimal setting of 1280 x 1240 pixels. Failure

to do may cause the dialog boxes to appear outside the viewing area. To find a window that should appear use the master screen curser Up / Down

arrows. All screens can be moved by clicking and holding the selected screen for personal viewing preferences.

3. After the software is loaded and the proper screen resolution is set, open the software and follow the steps below: Note: It is not necessary to

have the computer connected to the ASP-MG24 for viewing and program purposes.

Opening the Software

1. The screen should look like the view below. If not, close the software and restart.

2. If the ASP-MG24 is connected to the computer click “Yes “ to connect, or click “No” to work in Off Line mode.

3. To enter the control panel screen, click on the “Device 1” button. Note: A password can be inserted at any time. Click “Start” and then “Log On”.

Open the Device panel by clicking on “Device 1”. Note: An ASP-MG24 is also known as a “Device”. Multiple ASP-MG24 units can be controlled via

one GUI interface. If only one ASP unit is connected to the computer click on Device 1 and the main control window will appear.

Mic / Line Input

Input Meter

The bar graph meter illustrates the level of the input signal POST the channel’s gain control and is PRE input filters and compressor settings.

Gain

For convenience both Mic / Line inputs and the four masking generators levels are shown. Controlling the gain can be accomplished by dragging the

fader, using the up / down buttons or by typing in the number viewing text box. Channel Mute can be accomplished by clicking on the Mute tab. The

tab will illuminate red indicating the channel is in Mute. Input Polarity can be set by clicking on the Polarity tab.

Compressor

Inputs 1 & 2 have fully adjustable compressor limiters. When clicking on the compressor tab, two sub viewing screens will appear. Note: All control

boxes can be dragged for desired positioning of the screen. Screen 1 is an indicator screen showing the compressor / limiter operation. The second is

the settings screen. This screen controls Threshold, Attack, Release and Ratio. Adjustment can be made using the up / down arrows or by typing into

the data viewing text box.

• Threshold - Limit threshold. Ranges from -20dBu to +20dBu in 0.5dB steps.

• Attack - Attack time. Ranges from 0.3ms to 1ms in 0.1ms steps, and ranges from 1ms to 100ms in 1ms steps.

• Release - Release time. Can be set at 2X, 4X, 8X, 16X or 32X the attack time.

• Ratio - The Ratio control allows adjustment to the amount of Input vs. Output level with signals exceeding the set threshold limit.

Example: When set at “2”, a 2dB input signal increase yields 1dB output gain.
