The ONE-BOX Solution

mXa-1502 combines a 16-channel DSP Matrix Mixer, Advanced Speaker Processor and two-channel multi-mode Power-amplifier under one hood. Add to that, a healthy compliment of integration I/O for interfacing with other system components and the mXa-1502 is even harder to beat. All this fits into a simple, 1RU unit that easily goes just about anywhere. No other single unit currently available offers the flexibility, configurability and ease-use provided by the mXa-1502. You would even be challenged to find individual components that can be assembled to approach the mXa-1502s performance and features without significantly increased cost. You’ll spend less time selecting the right product, pre-configuring and wiring, not to mention dealing with multiple vendors, sales, A/R or tech support teams. One product: mXa-1502. One company: Ashly.

The mXa-1502 is literally a “system-in-a-box” and includes all the critical components for creating the ideal solution for a wide range of applications. These include:

A 16-input (8 Balanced Mic/Line inputs + 4 Stereo Unbalanced inputs) Mixer, which incorporates programmable Class A mic-preamps, full block-assignable DSP on every channel (Gain, Meters, Compressor, Leveler, Gate, Limiter, 10-band Parametric EQ, HPF & LPF, 31-band Graphic EQ, Signal Generator, Delay). Up to 6 independent functions can be assigned to every channel. Everything you’ll need to handle just about any source signal

  • 4 Independent Matrix Mixers, which are assignable to any or all of the unit’s 4 outputs. Each mixer can take any of the 16 inputs, each with fader control and metering, plus mute. Each mixer also incorporates a full-featured priority Ducking system for paging or priority miking and also a gain-sharing Auto-Mixer for all mic channels for use in meeting spaces. Create one mix for all outputs, or an independent mix for each output.

  • 4 Output channels with full DSP. Same functions as inputs, but adds Ambient Noise Control, Universal X-Over functions and FIR Filter import capability. This makes the mXa-1502 one of the most advanced zone and speaker system processors available.
  • 2-channel x 150W multi-mode Class D amplifier. Each channel of the amp section can be set to drive loads from 2-8 Ohms or constant voltage (25/70 or100V), You can mix and match speakers loads as needed, with one side driving up to four 8 Ohm speakers and the other a string of high-impedance ceiling speakers. Of course, the channels may also be bridged for a total of 300W, that can be used to drive a subwoofer or a larger 70/100V load. When you need to expand, the mXa-1502s dual AUX outputs can be used to connect to additional power when required.

  • Programmable Scheduler with Real-Time Clock. For those situations where unattended operation is required, the mXa-1502 can be programmed to operate in automated fashion. You can easily create a schedule for the mXa to automatically turn on/off, change presets, mute/unmute channels, activate triggers, page to zones, select sources and more. A built-in Real-Time Clock can be synced to other devices or a network time server for years of accurate timing reference. With this and many of the automatic mixer functions, the mXa-1502 practically drives itself.

  • Built for integration. To top it all off, we’ve equipped the mXa-1502 with a full complement of integration I/O: 8 GPI trigger inputs, 2-GPO Trigger outputs, 2 fault outputs (one for each amp channel), standby on/off port & 3 VC control ports. And of course-Ethernet. All programmable using the AquaControl interface to operate according to project requirements

  • Integrated Software Remotes. As if all the above weren’t enough, the mXa-1502 even provides built-in Remote pages, which can be served up on virtually any PC, Tablet or smartphone. No extra hardware required. Just intelligent control.
    • Mixer Remote: Provides access to any of the four available mixer sections in a simple, easy-to-use interface with faders, meters and channel On/Off functions
    • DVCA Remote: Up to four DVCA groups may be created and served as a remote -page
    • Virtual WR-5 Remote: One or more virtual WR-5 remote panels may be accessed on any small-format mobile device with preset recall, source select, channel mute, meter and fader functions, all accessible.

Collectively, these add up to a powerfully capable solution that can handle just about any task. All in a compact and affordable 1RU package. It’s an unbeatable combination!

Version History

mXa mXa-1502 Firmware V1.2.8.bin


Revision History

Updating AquaControl™ firmware on your Ashly mXa-1502.

NOTE: if firmware update fails, make sure v1.2.2 or higher is installed and try again.

The mXa-1502 uses embedded programs that run within the device, also known as firmware. On occasion, Ashly will release new firmware updates to improve operation or add features. In most cases this can be deployed in the field by the system administrator.

It is important to review the firmware revision history to determine if the update will add value to your installation. Although a firmware update is typically a routine procedure, there is a low level of risk that it can cripple the Ashly device, explained below:

Associated risk when updating.

If power to the Ashly mXa-1502 device is interrupted during the update procedure, there is a risk of disabling the device. Once the firmware update procedure has begun, any interruption can leave the Ashly device in a “crippled” state.

The crippled state can occur because the firmware update routine first erases the old firmware on the Ashly device, then writes in the new firmware code. If an interruption occurs during that process, the Ashly device can be left without a valid program to function or communicate further with a computer, tablet or mobile device. If this happens, the mXa-1502 may need to be returned to the Ashly Service Department to restore the factory flash program.

Installation Instruction:

Log into the mXa-1502 AquaControl(TM) software using an Admin level account.

The current firmware version is shown on the Dashboard landing page, in the Device information section.

To update the firmware navigate to the Settings -> General settings page, and click or press the “Update” button next to the current firmware revision text.

Click or press the “+ Firmware File” to locate a new firmware ‘bin’ file on your computer or mobile device, that you have downloaded from the Ashly Audio website.

Click or press “Install Update” to start the update process.

Hear from the engineers who built the mXa-1502

Remote Controllers


WR-1 Is a single-gang, wall remote that allows control of volume for any two (2) Input or Output channels on the mXa-1502. This is useful for maximizing the number of zones or areas that require control, while keeping hardware and installation cost to a minimum.


WR-1.1 Is a single-gang, wall remote that allows control of volume for any single Input or Output channel on the mXa-1502. This is great for when individual volume controls need to be located in each zone. Provides a simple and cost-effective remote option.


WR-1.5: This “combination” remote offers two control knobs in a single-gang, wall format. One knob allows control of volume for any Input or Output channel on the mXa-1502 and the other is for selection of exclusive functions such as any four Presets, Sub-presets or Sources. The WR-1.5 offers total zone control in a simple, intuitive form-factor.


For easy preset scene or source selection, the WR-2 remote’s 4 push-buttons allow selection of exclusive functions (Preset, Subpreset, Source Select 1-4) in a single-gang wall-mount format.

Virtual FR Remote Mixer Page

This virtual remote is built right into the AquaControl software, so it comes at no extra cost. It may be accessed from any iOS or Android browser-enabled device (such as a tablet or smartphone) connected to the mXa-1502 using a Wi-Fi router. It allows control of up to 16 Mixer channel levels as well as mutes (using the device’s touchscreen) and also meters per mixer page (1-4) that are set up using the AquaControl Software interface. It’s a convenient and easy-to-use fader interface for when live mix control is needed.

DVCA Remote Page

DVCA Remote Page Another “virtual” controller, the DVCA page is also a remote feature that is incorporated into AquaControl software. The DVCA remote provides touchcontrol of up to four (4) DVCA groups, which work as “Master Faders” for any assigned group of mXa-1502 Input or Output channels. Any wireless iOS or Android device may access the DVCA page for convenient control channel groups or zones.

Virtual WR-5 Remote Page

The Virtual WR-5 remote is designed to duplicate the hardware version wall remote for PnES-enabled models. It provides the same control functions for AquaControl, including 6 buttons, which may be used for Preset, Source Select, Muting and Fader Mode, as well as a programmable Channel fader and “LED” meter. It can be viewed from any browser-enabled smart phone
