Meter

There are four bar graph meters that illustrate the level of the output signal of the generator. It is POST the channel's gain control and PRE input filters.

Masking

When the Masking button is pressed a small window will open. This window allows the selection of either the White or Pink noise filter.

Ramp Time

The Power Ramp button sets the desired turn on signal ramp time during power up. The Time buttons allow adjustment of the amount of preset time needed. The amount of steps is a formula of gain divided by time. The ramp interval voltage change will occur every 6 seconds. The amount of dB steps will vary depending on the total ramp time selected and the change in gain from -40dB. Example: Choosing 2 minutes of ramp time with channel gain set to -10dB, use the following formula to calculate dB rate of change:

(Gain = -40dB minus -10dB = -30dB) and (Time = 120 seconds / 6 seconds = 20 steps) Gain Steps = 30dB / 20 steps = 1.5 dB change per second.

Ramp Bypass

If the Power Up Ramp button is illuminated green the ramp feature is engaged, if grey the feature is bypassed.

Program files can be saved to the PC or Laptop. It operates like any other Windows® files storing device. For convenience a file can be preprogrammed in demo mode, saved and loaded to the device.

Device Recall

The ASP-MG24 has a built in non-volatile memory that can store up 14 different program setups. A program can be recalled from the device. When doing so, only one program can be open on the desktop GUI. Once recalled, the program name and number will be at the top of the main screen.

Device Store

The ASP-MG24 has a built in non-volatile memory that can store up 14 different program setups. A program can be stored using this menu. The old program with the same program number will be replaced. Once the program is stored in the flash memory, it can be recalled at a later time, even after loss of power.

Owner's Manual

For Retrofit Sound Masking installations where the occupants are already in the space, this feature programs a one-time slow ramp to allow the occupants to become accustomed to the masking sound in the space.

1. Click the Initial Ramp Commission button.
2. Click the Start Date drop down menu and select the start date.
3. Set the start level for the masking signal, typically -10dB down from the target level.
4. Click the Days to End drop down menu and select how many days the scheduler will ramp up.
5. Click the Start Ramp button.

Once the Initial Ramp Setup is complete, the starting level is 10dB below the target level, and the device is programmed to take 10 days to return to the target level. The Bypass Ramp buttons allow the 4 masking channels to be bypassed.

Owner's Manual

The Scheduler allows the installer to program masking level changes over a 24 hour period, 7 days a week. A separate schedule can be configured for every day and can be copied to any of the 4 masking channels and the 2 inputs. This example shows Masking channel M1, with a program for Monday, ramping up slowly starting at 5am and ramping down starting at 4pm. The faders set the masking level from "0" level change down to -10dB. Drop down menus allow selection of any of the 4 masking channels and 2 inputs to be configured to a schedule, as well as choosing the day of the week to program. To reduce data entry time, create a schedule for one day and copy it to all the other days. The Channel 3 or "M1" schedule is getting copied to all the remaining 6 days.

Device Control

Enter device "name", as well as access Ethernet Setup for MAC Address, IP address, Gateway and Subnet Mask.

Import MEQ Data

Directly import files from the AtlasLED room measurement software called MEQ. This is an advanced feature, contact support for more details.
