The ACC3 is a multi condenser 3 microphone system for accordion. The system contains the latest components in micro electronics. The ultra low mass makes placement easier than other systems on the market today. The system comes with with the "Nano Blend" belt pack *Stereo Version. The stereo version is slightly different than the standard mono belt pack. The stereo version requires the player to use a Y cable. (1/4 in. stereo - Two 1/4 in. mono ends) The master volume control on the mono version is replaced with an on/off switch, and the GAIN contols on the mono version are replaced with volume controls.

Housing most of the electronics outside of the accordion makes installation less complicated. With fewer holes to drill, it is easier and more dependable over many years of use. The battery is changable outside of the accordion because it is located in the belt pack. It's small size and low mass gives the end user the ability to permanently or temporarily Nano Blend Belt Pack Controls.

mount the microphone without major modifications to the accordion.

The ACC3 comes with a wiring harness allowing installation of the bass mic through the bellows and mounted close to the bass machine. Some modification maybe necessary to accommodate the third microphone.

The system is best suited for mic level inputs (PA systems) but also works with line level amps. Both ACC1 & ACC3 will be wireless capable, able to be interfaced with major brand wireless products. The 9 volt battery life for operation is between 80-120 hours of intermittent use before replacement. The output of this system is activated by the quarter inch jack output when plugged in.

The ACC3 Stereo version has mixing capabilites right on the belt pack. The belt pack has two Volume controls to adjust the volume of the right hand microphones in relation to the left hand microphones. The belt pack also has trim filters. The trim filters only cut the highs / and or lows for both the right and left hand independently. You cannot boost highs or lows, this features is designed to help the players with feedback in certian rooms.

Stereo version must be used with a Y cable. (NOT provided) A Y cabel is a special cable with a Stereo 1/4 inch on one end and two mono 1/4 inch on the other. The player can pick a Y cable up usually at an accordion repair / install shop. Most AMT Accordion dealers should be able to offer this cable.

Wireless Ability:

The ability to use the ACC3 Stereo wireless is possible but maybe difficult. You will first need a short Y cable that it not supplied. Then you will need TWO wireless transmitters that accept 1/4 inch cables. You'll have three belt packs on at this point.

For an easier Wireless solution, we highly recomend using the ACC3 Mono version.

Other:

A typcial setup is for an ACC3 mono or stereo with a 120 bass accordion is to place two microphones in the grill and one microphone in the compartment which houses the bass machine. A wire / signal is wired from the left hand and into the right hand or grill side. In some situation, accordion players have no need to provide amplification for the left hand. If this is the case, during the install, you can choose to not wire the left hand with microphones. Instead you could either place the third microphone into the grill of the accordion to accompany the Right hand microphones or just choose to not install the single left hand microphone at all.

If the player has two accordions, it is possible to fit two seperate accordions with wiring and microphones and use the same belt pack. A common choice is for the player to have a mono and a stereo system, wiring two seperate accordions the exact same way. At this point, the player then has there choice of using the mono or stereo belt pack.
