PureBand¢â Crossover System
Crossover Filter: Linkwitz-Riley 24dB per Octave
:NAMESPACE PREFIX = ST1 />Crossover Frequency Range: 50 HZ - 3 kHz
Crossover Mode: Crossover (CH1=LPF, CH2=HPF), LowPass (both channels LPF), HighPass (both channels HPF), Bridge (LPF or HPF).
Peakx¢â limiters: Channel independent clip limiter designed to provide maximum output while protecting your loudspeakers |
Input/Output |
Input Connectors: XLR (one per channel), 1/4-Inch (one per channel), and RCA (one per channel). 1/4-Inch connectors can be used as loop-thrus to distribute signal to additional amplifiers.
Output Connectors: Two 4-Pole Speakon? Output Connectors accept 2-pole or 4-pole Speakon? connectors. The top Speakon connector is wired for both channels so it can be used for bridgemono wiring or for stereo wiring of two speakers to a single Speakon connector.
One pair of back-panel binding posts per channel; accepts banana plugs or bare wire. (European models do not accept banana plugs.) |
