10 B ELECTRONIC CROSSOVER

Bryston’s 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 purity is always maintained.

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 f or the drivers. You can also independently select

crossover slope, from 6, 12, or 18dB/Oct., where one driver

requires raster cutoff than another in the same system.

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.

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 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 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 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 unapproached

in other crossovers.

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

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.
