1 Brystons Model 10B Electronic Crossover combines ideal signal-handling with an enormously flexible control function. Simple, direct f ront-panel switches allow any crossover curve to be set instantly, and the signal purity is always maintained. MODEL 10B LR The 10B-LR , a fixed f requenc y plug in Linkwitz-Riley a l i g n m e n t w i t h s t e e p ro l l o f f c u r ve s o f 2 4 d B / O c t . i s also available. The crossover may be used in any of three connections: 2-way stereo, 3-way mono, and a special configuration, 2-way stereo with summed low pass out to allow the use of one sub-woofer. The 10B is available in two stock versions, a 10B sub incorporating f requencies more suitable to sub-woofer applications and a 10B standard which is more applicable to speakers reacquiring f requency control in the midband and tweeter areas. All crossover selections are extremely accurate and repeatable, being implemented with 1% selected metal-film resistors and polystyrene capacitors. All switches are heavily gold- plated, for lifetime protection f rom corrosion. The level- controls are precise 1dB increments, also derived f rom gold-plated switches and 1% metal-film resistors. Most important, however, is that the Bryston 10B Crossover uses NO integrated circuits in the signal path. All internal buffer and amplification stages are Brystons exceedingly linear and superbly quiet discrete op-amp circuitr y. This means the signal is always maintained as Audiophile Q uality , with stability and f reedom f rom noise and distortion unapproached in other crossovers. From the point of view of adaptability, flexibility and signal integrity, the Bryston 10B Electronic Crossover is the ideal choice for the widest range of multi-way speaker installations. 10 B ELECTRONIC CROSSOVER The Model 10B features independently selectable crossover points for high-pass and low-pass, in case the speaker installation requires slightly overlapped, (or slightly staggered), response cur ves f or the drivers. You can also independently select crossover slope, f rom 6, 12, or 18dB/Oct., where one driver requires raster cutoff than another in the same system.
