MX A-170 170W PA Mixer Amplifier with USB MP3 Player
The MX A-170 PA Amplifier is a PA mixer amplifier rated at 170 watts, built for fixed public-address installations: schools, temples, mosques, churches, offices, factories, showrooms and small auditoriums where announcements and background music must reach many speakers from one central unit. It combines a mixer, a power amplifier and a digital media player in a single rack-mountable chassis, so a complete small PA system needs only speakers, microphones and this amplifier.
The front panel is the whole control surface. Five microphone inputs each have their own volume control, two AUX inputs cover music sources, and bass and treble controls shape the overall sound. A built-in MP3 player with an LCD display and remote control plays from a USB disk or an SD or MMC card, and it also supports radio, Bluetooth, equaliser settings and recording, so background music does not need a separate player. A preamplifier and line output allow a booster amplifier to be added later or a programme to be recorded.
Why Choose MX A-170 170W PA Mixer Amplifier with USB MP3 Player?
Why choose the MX A-170 PA Amplifier over a simple power amplifier? Because most PA jobs are mixing jobs, not just amplification jobs. An announcement microphone, a second microphone at another counter, a music source and perhaps a wireless receiver all need different levels at different times, and the A-170 gives each microphone its own volume knob plus independent bass and treble control. The resettable circuit protector and the output short-circuit protection with alarm, overheating and saturation-distortion warnings add the safety margin a permanently installed unit needs.
The output section is equally practical. A 100-volt constant-voltage output suits long speaker lines with many ceiling or wall speakers tapped to different wattages, while 4-ohm, 8-ohm and 16-ohm outputs cover direct low-impedance speakers. Provision for a 12-volt battery keeps announcements possible during a mains failure, and the emergency-broadcast erase function lets an urgent message override the programme. These are the features that separate a PA amplifier from a home stereo amplifier.
Key Features
170W rated PA output: a PA mixer amplifier of 170 watts rated output, with 175 watts RMS at 10 percent THD and 150 watts RMS at 5 percent THD as listed for this model.
5 microphone and 2 AUX inputs: five microphone inputs with independent volume control and two AUX inputs, plus a line output for a booster amplifier or recording.
Built-in MP3 player with remote: a digital MP3 player with LCD display and remote control for USB disks and SD or MMC cards, with radio, Bluetooth, equaliser and recording support.
100V and low-impedance outputs: a 100-volt constant-voltage output together with 4-ohm, 8-ohm and 16-ohm resistance outputs for different speaker layouts.
Protection and emergency functions: a resettable circuit protector, output short-circuit protection with alarm, overheating and saturation-distortion warnings, and an emergency-broadcast erase function.
12V battery provision: provision for connecting a 12-volt battery, so announcements can continue when mains power is interrupted.
Best Suited For
The MX A-170 PA Amplifier suits schools and colleges, places of worship, offices and factories, hospitals and clinics, showrooms, restaurants and small auditoriums that run ceiling or wall speakers from one point. It is the right unit when several microphones and a music source must be mixed and sent to many speakers, and when a 100-volt line is the sensible way to wire the building.
Setup and Connection Guide
Decide the speaker layout first: 100-volt line speakers with matching tappings for long runs and many speakers, or low-impedance speakers on the 4, 8 or 16-ohm terminals for a small direct setup. Never connect both output types to the same speakers.
Connect microphones to the mic inputs and music sources to the AUX inputs, set each microphone volume individually, and use the bass and treble controls to keep speech clear without boom.
For background music, insert a USB drive or SD card with MP3 files, select the player source, and use the remote to change tracks; the player signal can be mixed with most microphone and AUX inputs.
To add a booster amplifier later, use the preamplifier and line output rather than overloading the speaker terminals, and keep the 12-volt battery connection ready where uninterrupted announcements matter.
If the protection trips, reduce the load and check for a shorted speaker line before resetting; repeated tripping means a wiring fault, not a faulty amplifier setting.
Frequently Asked Questions
Can the MX A-170 PA Amplifier drive ceiling speakers across a building?
Yes. Its 100-volt constant-voltage output is made for exactly that: many speakers on long cable runs, each tapped to a suitable wattage, without the impedance calculations a low-impedance system would need.
Do I need a separate music player?
No. The built-in MP3 player with LCD display and remote control plays USB disks and SD or MMC cards, supports radio and Bluetooth, and can be mixed with the microphone and AUX inputs for background music between announcements.
What happens during a power cut?
The amplifier provides for a 12-volt battery connection, so announcements can continue on battery power where a battery is installed. Battery capacity and speaker load decide how long that backup lasts.
