The S25B is the original acoustic bass system.  In 2013, AMT has released yet another refinement of the bass systems.  The S26 series adjustable tail piece mounting bass system is the most current tail piece mounting which is intended to quickly attach to the tail piece while allowing plenty of adjustable goose-neck in order to place the microphone in many positions.  You can view the optional models, mountings, and preamps by choosing “optional models”.

The S25B is an electret-condenser microphone that has been designed for acoustic bass. All of the parameters that are problematic for the double bass have been addressed. To be able to get the most gain before feedback it uses a very tight pattern to give a high rejection to surrounding noise, at the same time reproducing accurately the subtleties of the bass. As placement is especially important with an instrument that has a fine finish and varying dimensions, this microphone’s attachment mechanism is designed to secure the mic to the bass in different positions taking seconds to attach. This mechanism is fitted with natural soft suede so as not to mark or mar instrument.

Made from aluminum to keep the mass low yet extremely strong, this microphone will remain durable through many years of use.  The flex arm is easy to position yet retains it’s placement throughout the most active of performances.  The mic has an LED that can be easily seen while performing.  This indicates status of a battery or phantom power.

The pre-amp for the microphone is rugged anodized aviation aluminum, which houses the electronics that can be placed on the floor.   The pre-amp runs off of battery or phantom power.  The output is terminated with a male XLR type connector for balanced use.  The mic is connected to the pre-amp by a four pin locking connector.
