Ashly FX750.4 4-Channel Professional Power Amplifier

Save time, space, and money on your next audio amplifier installation with the Ashly FX750.4, a multipurpose installation amplifier with integrated DSP and a built-in WAP hotspot for simple connection and configuration via Wi-Fi as well as an intuitive web-based software UI. The amplifier also features an Ethernet connection for wired LAN connections—no network router required.

The four-channel Class-D amplifier supplies 750W of power per channel or 1500W per bridged pair. The onboard DSP provides all the facets of a standalone speaker processor, complete with EQ, delay, compression, limiting, phase, and more. It's a complete solution that's simple to set up and navigate. The FX750.4 includes a pair of rack ears, a power cord, and block connectors.

Intelligent DSP

Powerful DSP engine that can be configured to suit a wide range of tasks without the need for additional equipment. From processing input sources, routing, and output DSP that can fine tune the sound of any speaker. Everything you need is right there. These can route into Zones A-D and then into the 4 outputs.

4-channel DSP configuration including:

• Input processing

• Zone processing

• Output processing

• Speaker processing

• Device settings

The FX Series is capable of handling a variety of applications, such as:

• Multi-zone music distribution for retail and restaurant/bar

• Noise masking for offices and medical facilities

• Media playback for hotel lobbies, retail, and museum kiosks

• Mobile sound

The FX DSP engine provides a rich selection of functions for getting the most out of your system. Here’s what you get with the FX onboard DSP:

• Dashboard: status display, level control, and metering for Zones A-D

• Inputs: Gain/Trim, Sensitivity

• Zones: source select, mono/stereo, level control, and metering as well as GPIO assignment and Compressor for Zones A-D

• Outputs: Routing (from Zones A-D), Delay (up to 100ms), 10-bands of fully parametric EQ for outputs 1 through 4 

• Speaker presets: Save/Load/Select from Library, Custom: X-over and Gain, 11-band speaker EQ (fully parametric), FIR filter import, Speaker alignment delay (up to 10ms), Polarity, Limiter (Clip, Peak, and RMS), and Output mode (Low/Hi-Z)

• Settings: System and Device info, Backup and Restore, Speaker Preset Library, Power Management (standby/sleep, auto/manual), GPIO settings, LAN, and Wi-Fi

The amplifier provides 4 mic/line inputs, so you get the power of a 4-input mixer, zone matrix, plus output and speaker processing. With all that, FX can be a true “one-box” solution for many applications.

Intuitive Software UI

• To control FX’s powerful DSP, you’ll find its user-friendly software interface that offers an intuitive workflow and easy access to FX’s most advanced functions. A webpage-like directory on the left-hand side of the UI keeps all necessary functions clearly visible and accessible at all times. No multi-page layering, no right-click or hidden menus, and no getting “lost in the weeds”.

• FX Dashboard: Quickly see the amp’s status displayed, along with Zone controls. The directory then takes you through the signal flow from Inputs to Zones to Outputs, followed by general settings—easy and simple.

• Create, save, and load speaker presets to accommodate virtually any loudspeaker. These can be loaded independently per channel, so different speakers may be used for different zones, or satellites and subs may be used for a bar or auditorium.

• The FX UI screens are well laid out, with consistent controls from page to page that are informative and easy to read. All device information and operations are at your fingertips. From input / output settings and remote assignments to power and IP.
