Simple, direct front-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 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 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 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 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. 1 10B SWITCHING AND CONNECTIONS (E) (D) (C) (F) (B) (A) (H) (G) (A) (F) (A) (B) (C) (D) (E) (I) (K) (L) (K) (J) (I) (J) (F) HIGH PASS FREQUENCY SELECTOR 12 selectable crossover points (G) STATUS LEDS (H) POWER SWITCH (PUSH BUTTON) (I) INPUT RCA OR XLR (FEMALE) (J) LOW PASS OUTPUT RCA OR XLR (MALE) (K) HIGH PASS OUTPUT RCA OR XLR (MALE) (L) MODE SELECTOR SWITCH (A) MUTE SWITCH One each for low pass and high pass filters (B) LOW PASS FREQUENCY SELECTOR 12 selectable crossover points (C) LOW PASS SLOPE SELECTOR Sets low pass slope in decibels per octave (6, 12 or 18dB/Oct.)

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 resulting 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 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 PowerPac’s would be ideal for use in this capacity. POWERPAC 120 SST MONAURAL AMPLIFIER The Bryston PowerPac 120-SST amplifier, is a superior quality, modular, single channel power amplifier delivering 120 watts at 8 Ohms, or 200 watts into 4 Ohms. The PowerPac 120-SST is essentially a monaural version of our very popular 3B-SST stereo amplifier but intended for use in applications where portability and flexibility are of prime importance. POWERPAC 300 SST MONAURAL AMPLIFIER The Bryston PowerPac 300-SST amplifier, is a superior quality, modular, single channel power amplifier delivering 300 watts at 8 Ohms, or 400 watts into 4 Ohms. The PowerPac 300-SST is essentially a monaural version of our very popular 4B-SST stereo amplifier but intended for use in applications where portability and flexibility are of prime importance.
