The AMT S25B - TP(Tail Piece) is the newest addition to the bass microphone lineup from AMT. The TP systems are identical in sound to the standard S25B and SP25B systems however mount to the tail piece for a more permenant setup. For a microphone that can easily be moved from bass to bass while traveling, please see the S25B or the SP25B.

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.

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 pre-amp for the microphone is rugged anodized aviation aluminum, which houses the electronics that can be placed on the floor. This pre-amp utilizes a circuit that can change EQ, curve, and gain by exchanging EPROM-like chip. 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. The system includes a cable that disconnects from the microphone.
