Five (5) Studio-Grade microphone capsules. 

The AC 501-HQ is currently the best value-for-money professional treble-only accordion microphone on the market, as it combines the quality and innovation developed by HARMONIK® with excellent performance microphones. Designed specifically for TexMex 31-34 button diatonic models and small piano models.  

High-Fidelity Electronics

The conditioning circuit of the AC 501-HQ microphones utilizes electronic components and amplifiers with the lowest noise, with high precision and low harmonic distortion, producing excellent sound fidelity. The production of the AC 501-TM uses the latest electronic manufacturing processes, which ensure a product of high quality and a finishing touch.

Uniform Sound Capture

With three directional microphones, this system is able to capture the full extension of buttons at the same level, from the lowest to the highest notes.

High Feedback Resistance

The AC 501-HQ is a system with high feedback resistance, as the combination of its directional microphones with high fidelity electronics enable the system to ignore external sound up to 10dB.

Applied Innovation

Harmonik has developed a unique Shock-Mount® system for its microphones, which mechanically isolates the microphones in the body of the accordion, absorbing the mechanical vibrations that are produced whilst playing. This results in a much clearer and more natural sound. 

Reliability

The AC 501-HQ system uses a Neutrik® jack, which guarantees the musician the best electrical contact the moment the cable is plugged in. The high quality, sealed potentiometers prevent any dust particles from entering into the electrical contacts, guaranteeing a longer volume control circuit life. In addition, the AC 501-TM uses the highest-standard locking connectors, ensuring the best connection quality.

Versatility

The AC 501-HQ has no need for external circuits in order to work, simply requiring a P10 mono cable or your choice of wireless system. No need for phantom power – just plug and play! 

Easy installation

No need to worry about installation problems, as the AC 501-HQ comes with cables and adapters that are easy to use and replace, on top of their intuitive layout.
