Ahuja MX 15 Mixer (12 Channel)

Ahuja MX-15 Mixer

The Ahuja MX-15 is a general-purpose PA mixer preamplifier for venues that run many microphones through one simple control point. It provides 12 microphone inputs and 3 auxiliary inputs — 15 inputs in total — each with its own on/off switch and LED indicator, plus a master control, active bass and treble controls, four line outputs and a headphone output for monitoring. It is a preamplifier mixer: it combines and controls sources at line level and feeds separate power amplifiers, which keeps a hall, conference room or place of worship system easy to operate and easy to expand.

Key features

• 12 microphone inputs rated 0.6 mV at 4.7 kilohms
• 3 auxiliary inputs for music and line-level sources
• On/off switch with LED indicator on every input
• Four line outputs to feed several amplifiers or boosters from one mixer
• Two preamplifier outputs and a headphone output for monitoring
• Active bass and treble controls, plus or minus 10 dB
• Runs on 220 to 240 V AC mains or a 12 V DC supply

Inputs for speech-heavy venues

Twelve microphone inputs cover the reality of halls and houses of worship: a main speaker, panel or choir microphones, and spares for guests, all live at once without repatching. The three auxiliary inputs take music players and other line-level sources — two at 100 mV into 470 kilohms and one at 500 mV into 100 kilohms. The per-input switch and LED remove the most common operating error in shared venues: nobody has to guess which channels are live, and unused inputs are switched off rather than left open to add noise. One master control then sets the overall level for the whole mix, so a non-technical operator can run the system confidently.

Outputs and system building

Four line outputs at 1 V let one MX-15 feed multiple power amplifiers — for a main hall and overflow rooms, or for staged expansion as a venue grows — while two preamplifier outputs at 200 mV serve recording or an additional booster. The headphone output lets the operator check the mix before and during an event without walking the room. Frequency response is 20 Hz to 20 kHz within plus or minus 3 dB, distortion is under 1 percent and signal-to-noise ratio is 50 dB, figures suited to speech and programme material in PA service.

Power and installation

The MX-15 runs from 220 to 240 V AC at 50/60 Hz, and it also accepts a 12 V DC supply such as a vehicle battery, so announcements can continue where mains power is unreliable or unavailable. The cabinet measures 350 x 145 x 200 mm and weighs 3.9 kg, compact enough for a tabletop, a small rack shelf or a portable PA trolley. Setup practice is simple: start with channels down, raise the master, bring up one microphone at a time, switch off idle inputs, and keep microphones behind the loudspeaker line to control feedback.

For auditoriums, seminar halls, schools, temples, churches and community venues that need many microphones combined into one clean, controllable PA feed, the MX-15 is a proven, deliberately simple answer — input count and operational clarity first, with no features an operator has to work around.
