Introduction to the SIP-301:
In the early 1980’s Roland produced some of its most acclaimed rack mount effects processors. This series included the SIP-300 Guitar preamp, the SIP-301 bass preamp, the SBF-325 voltage-controlled, stereo rack-mount flanger, the famous SDD-320 Dimension D chorus unit, the SRE-555 rack-mount version of the RE-501 tape-delay/chorus, and the SPV-355 pitch-to-voltage analog synthesizer.
The SIP-301 is a versatile analog bass preamp. There is a high and low gain input, followed by an excellent analog compressor. The compression can be disabled using a foot switch. After the compression section is an optional effects insert, then a very flexible three-band equalizer, with high and low cut filters. Each band in the equalizer has two selectable frequencies as well. After the equalizer there is another effects insert! Then a volume control which feeds directly to the front panel XLR output, and a master volume control that feeds to a pair of unbalanced outputs, one of the front panel, and one on the rear panel. The master volume also feeds a built-in crossover network, with high and low outputs on the rear panel as well.
The SIP-301 is a fully professional unit that can be used simply as a direct box for Bass or any high-impedance input, or it can be used as a additional processor to add some analog quality sound to any sound source.
