Mosque sound made simple

Digital Mixer Amplifier MX-6224D


You just found the perfect solution for your community’s mosque sound system: the all-in-one compact

Digital Mixer Amplifier MX-6224D

TOA’s MX-6224D was designed specifically for mosques – making it the perfect choice for every small and medium sized mosque sound system. Two 240W amplifiers, a mixer with digital sound processor and a built-in effector have been combined to obtain an ­all-in-one system that best supports your every requirement.






Compact all-in-one device
The Digital Mixer Amplifier MX-6224D incorporates a DSP function, a built-in effector, and 2 x 240W class-D amplifiers.

Optimized microphone sensitivity
Microphone sensitivity corresponds to the distance between the microphone and the imam.

Pre-programmed sound effects
Digital effects for microphone inputs. Built-in effector realizes celestial sound even in small mosques. Selectable reverberation out of 12 patterns.

Easy operation
TOA has created the MX-6224D specifically to cater for medium and small houses of worship. The MX-6224D is a reliable and simple system, needing very little technical knowledge to operate, yet still maintains exceptional sound quality.

Superior sound quality
Built-in amplifiers and digital signal processing with pre-set special effects combined with technically matched microphones and speakers comprise perfect sound and voice intelligibility.

Optimize the sound according to your premises
Control the output level meters for inside and outside, reduce feedback with the built-in 3-band equalizer, use the pre-set effects for your voice and for your rooms: delight your congretation with celestrial sound even in small mosques.

Built the sound solution for your mosque

Combine the MX-6224D with matching speakers and microphones for perfect sound



The built-in speaker EQ, optimized for TOA’s TC Series Horn Speaker and ­BS-1030 Universal Speaker, reduces acoustic feedback and ensures voices are more intelligible. Furthermore, loudspeakers for outside are less vulnerable to damage, thanks to the high-pass filter, and thereby last long time.

Outdoor Speakers

TC Series Reflex Horn Speaker

High durability, heat-resistance, and improved low frequency, thanks to polyamide diaphragm and weatherproof materials.

TH Series Reflex Horns

Shock-resistant aluminum round horn. Superb weatherproofing and corrosion-resistance thanks to the external stainless steel hardware and powder-coated horn and bracket.

TU Series Driver Units

Designed to be used in combination with TOA’s TH-650 or TH-660 Reflex Horns.

Indoor Speakers

BS-1030 B/W
Wall-Mount Box Speakers

High (100V) impedance with 30W of rated output. Easy to install with included bracket. Comes in black (B) or white (W).


Lavalier Microphone

Electret condenser element with hypercardioid pattern. Works best when attached to the chest area.

Unidirectional Microphone

Dynamic, cost-effective performance.

Unidirectional Microphone

Dynamic, rigidly constructed and minimal handling noise.

System Advantages

Sophisticated options
Make your system easily usable for a single person with the remote control. The speakers are not only proteced by a high-pass filter, they can also be boosted by driver units.

Adjust the system to your needs
The internal and external zones are individually adjustable – allowing for you to set the system up just the way your building requires.

Long-lasting Japanese quality
Japanese engineering brings you high-quality performance and regularly tested products. TOA ensures that products comply with various regulations and standards around the world – so that our customers have complete peace of mind when using our quality products.

Solutions for acoustically difficult environments
TOA developed a software for the simulation of an acoustic setting. The TOA speaker placement viewer allows virtual placement of speakers to plan the setting of a sound system beforehand – so you can be sure that everything actually goes according to your plan.
