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 curves for the drivers. You can also independently select crossover slope from 6, 12, or 18dB/octave, where one driver requires faster cutoff than another in the same system. A fixed-frequency plug in Linkwitz-Riley alignment with steep roll-off curves of 24dB/octave is also available.
The crossover may be used in any of three internal 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 crossover is available in three stock versions; 10B-SUB incorporating frequencies more suitable to sub-woofer applications (40Hz to 500hz), 10B-STD which is more applicable to speakers requiring frequency control in the mid-band and tweeter areas (70Hz to 4500Hz) and the 10B-LR, which uses plug in resistor programming cards to set the crossover frequency. Both the 10B-SUB and 10B-STD crossovers include a mode called Mono Low Pass (see below) which replaces the Two Way Mono (Linkwitz-Riley) mode in older model 10B’s. The Two Way Mono mode (see below) is retained in the 10B-LR allowing for very steep (non Linkwitz-Riley) 8th order filters.
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 from corrosion. The level controls are precise 1dB increments, also derived from 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 Bryston's exceedingly linear and superbly quiet discrete op-amp circuitry. This means the signal is always maintained as "Audiophile Quality," with stability and freedom from noise and distortion unmatched 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.
