1、RadioFans.CN 收音机爱 好者资料库 RadioFans.CN 收音机爱 好者资料库 BRYSTON SST PERFORMANCE DRIVEN 1 Brystons Model 10B Electronic Crossover combines ideal signal-handling with an enormously flexible control function. Simple, direct front-panel switches allow any crossover curve to be set instantly, and the signal puri
2、ty is always maintained. MODEL 10B LR The 10B-LR, a fixed frequency plug in Linkwitz-Riley alignment with steep roll off curves of 24 dB/Oct. is 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
3、pass out to allow the use of one sub-woofer. The 10B is available in two stock versions, a 10B sub incorporating frequencies more suitable to sub-woofer applications and a 10B standard which is more applicable to speakers reacquiring frequency control in the midband and tweeter areas. All crossover
4、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
5、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 circuitry. This means the signal is always maintaine
6、d as “Audiophile Quality”, with stability and freedom from 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
7、. 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 curves for the drivers. You can also independently select crossover slope, from 6,
8、 12, or 18dB/Oct., where one driver requires raster cutoff than another in the same system.

The PowerPac Amplifiers are a perfect choice for use as a portable power amplifier which can be attached directly to the rear of your loudspeaker. This provides for the use of very short speaker leads resulti
15、ng in a much improved loudspeaker/ amplifier interface. The PowerPac Amplifiers can also be bolted on the wall for utilization in audio/video surround systems (left/right/center/rears/backs) where a non-conspicuous power module is required. A further application would be in multi-room audio systems
16、where single or multiple amplifiers are needed to provide music in adjacent rooms. Finally, with the recent popularity in passively or actively amplifying the individual drivers in your stereo loudspeakers the Bryston PowerPacs would be ideal for use in this capacity.
