The SP25B is the same microphone as the S25B however uses the “super pre-amp” which has 2 XLR outputs, one of which has a ground lifted isolation transformer split. A quarter inch line driver output with volume control is also included. The pre-amp runs off of battery, phantom power, or optional power supply.
The SP25B 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. 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, phantom power or optional power supply. The mic is connected to the pre-amp by a four pin locking connector.

The 'Super Pre-Amp' has 3 outputs. There are two XLR outputs. The one on the left is your regular output to standard use. The one on the right (in red) is the isolation transformer. If you are playing with a PA and start to hear a 'hum', move the connection from the standard XLR output to the isolation or red output. This should eliminate the 'hum'. The 1/4 inch output is your line driver. You can use the line driver in conjunction with your amp, and send the XLR signal to the house PA or recording device. The Pre-amp works with Phantom Power or a 9-volt battery. We recommend using the 9-volt battery all the time. The line driver and isolation transformer will not work unless you have a 9-volt battery in the pre-amp.
The external volume control is for the line driver / 1/4 inch output. The preamp also has an internal volume control that you can adjust with a screw driver. You should only use this if more or less gain is required to match the gain on your existing amplifier.
