The OBL-2-2 is a special version of the OBL-2 that has been designed specifically to work with organs having built in speakers and a separate reverb channel, like the Hammond A-100, E-100, M-100 and S-100. Like the standard OBL-2, the OBL-2-2 allows the organ to be connected via a 1/4" output jack to an external amplification system. The unit has both an overall output and one that is low pass filtered. The low pass output provides a signal with the upper frequencies attenuated and is useful when using a bass amp to reinforce the organ low end. A level control is provided to allow the output signal to be adjusted to match the amplifier input requirements. For applications requiring a very low signal level, a jumper allows further attenuation of the output.
