The quality of that amplification shapes everything you hear — every movie moment, every music performance, every spatial detail.\u003c\/p\u003e\n\u003cp\u003eThe Bryston 9B³ is the five-channel version of Bryston’s legendary 9B series. It delivers 200 watts per channel. And unlike most multi-channel amplifiers, it is not a single large amplifier divided into five sections.\u003c\/p\u003e\n\u003cp\u003eEach of the five channels is a fully independent, self-contained module — its own circuit board, its own power supply, its own toroidal transformer. No channel shares power with any other. The five channels are independent in the same way that five separate monoblock amplifiers would be.\u003c\/p\u003e\n\u003ch3\u003eWhy Independent Power Supplies Matter\u003c\/h3\u003e\n\u003cp\u003eIn most multi-channel amplifiers, all channels share one power supply. When one channel demands a surge of power — a loud film effect, a bass transient — it draws from the same pool as the others. That competition shows up as compressed dynamics and a flattened sense of space.\u003c\/p\u003e\n\u003cp\u003eThe 9B³ eliminates this problem. Each channel draws from its own dedicated supply. A loud moment on the center channel has no effect on what the left or right channels can deliver. All five channels can run at full rated power at the same time.\u003c\/p\u003e\n\u003ch3\u003eThe Salomie Circuit — Bryston’s Patented Innovation\u003c\/h3\u003e\n\u003cp\u003eEvery Cubed Series amplifier uses Bryston’s patented Salomie input circuit, developed with the late Dr. Ioan Alexandru Salomie. According to Bryston, the circuit uses an array of 12 active devices at the first gain stage to act as a super-linear input buffer.\u003c\/p\u003e\n\u003cp\u003eThe buffer’s job is to catch and remove distortion and noise before they enter the main signal path. In most amplifiers, anything that gets into the input gets amplified right along with the music. The Salomie circuit stops that before it starts.\u003c\/p\u003e\n\u003cp\u003eBryston describes the results as dramatically less input-stage distortion, improved rejection of electromagnetic and radio-frequency noise, and standby power below 500mW. The 9B³ is the first five-channel Bryston amplifier to include this circuit.\u003c\/p\u003e\n\u003ch3\u003eModular Design — Built for the Long Term\u003c\/h3\u003e\n\u003cp\u003eThe 9B³ is orderable in three-, four-, or five-channel versions. Additional channel modules can be added later as your system grows. And if a channel ever needs service, it can be removed and replaced independently — without returning the whole amplifier.\u003c\/p\u003e\n\u003cp\u003eThis modular serviceability is rare in multi-channel amplifiers. Most competing designs require the entire unit to be returned for even a single-channel repair. The 9B³’s construction makes long-term ownership significantly more practical.\u003c\/p\u003e\n\u003ch3\u003eNetwork Monitoring and Control\u003c\/h3\u003e\n\u003cp\u003eThe 9B³ has a built-in Ethernet port that hosts its own web page. From any browser on your network, you can monitor each channel’s temperature, see clipping alerts, mute individual channels, and power the amplifier on or off. Firmware updates can also be applied this way.\u003c\/p\u003e\n\u003cp\u003eFor custom installation and home automation, an RS-232 serial port integrates with Crestron, Control4, Savant, and similar platforms. A DC trigger input and output handle automated power switching with processors and other components in your system.\u003c\/p\u003e\n\u003ch3\u003eSoftStart — Protection Built In\u003c\/h3\u003e\n\u003cp\u003eSoftStart is a microprocessor-controlled startup sequence. When the 9B³ powers on, it gradually ramps up its current draw instead of pulling full load all at once. This protects your speakers from startup transients and prevents tripping household circuit breakers — a real concern with a 65-pound amplifier drawing significant startup current.\u003c\/p\u003e\n\u003ch3\u003eBuild and Finish\u003c\/h3\u003e\n\u003cp\u003eThe chassis is machined and anodized aluminum. The black faceplate carries green LED status indicators — one per channel. The 19-inch version includes front-mounted handles for rack installation. The amplifier is fully convection cooled: no fans, no noise in operation.\u003c\/p\u003e\n\u003cp\u003eEvery 9B³ is built by hand in Dwight, Ontario, Canada. Bryston backs it with a 10-year parts-and-labor warranty.\u003c\/p\u003e\n\u003ch3\u003eWho Is This Best For?\u003c\/h3\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/2714.svg\" alt=\"✔\" width=\"15\"\u003e \u003cstrong\u003eHome theater builders who won’t compromise\u003c\/strong\u003e — A shared-power amplifier will always make dynamic tradeoffs under load.

Because each channel has its own power supply and transformer, these figures are available on all five channels simultaneously. Demanding speakers on every channel do not reduce what any individual channel delivers.\u003c\/p\u003e\n\u003ch3\u003eFive Independent Modular Channels\u003c\/h3\u003e\n\u003cp\u003eEach channel is a removable assembly with its own circuit board, power supply, toroidal transformer, inputs, and speaker outputs. No channel shares components with any other. If one channel needs service, it can be pulled and replaced without taking the rest offline.\u003c\/p\u003e\n\u003cp\u003eModules can be purchased separately and added later. Start with a 3- or 4-channel unit and install the additional module when your system is ready for it.\u003c\/p\u003e\n\u003ch3\u003ePatented Salomie Input Circuit\u003c\/h3\u003e\n\u003cp\u003eEvery channel uses Bryston’s patented Salomie input circuit — 12 active devices at the first gain stage that act as a super-linear buffer. According to Bryston, this removes distortion and filters out EMI and RFI interference before they reach the amplification stage. Standby power is less than 500mW.\u003c\/p\u003e\n\u003ch3\u003eSwitchable Gain — 23dB or 29dB\u003c\/h3\u003e\n\u003cp\u003eA front-panel switch selects between two gain levels. 23dB suits processors with a higher output level. 29dB suits lower-output sources or when extra sensitivity is needed. Correct gain selection keeps the processor’s volume control in a comfortable, usable range and avoids amplifying the noise floor along with the signal.\u003c\/p\u003e\n\u003ch3\u003eBalanced XLR and Single-Ended RCA Inputs\u003c\/h3\u003e\n\u003cp\u003eEach channel has both a balanced XLR input and a single-ended RCA input. Balanced connections reject common-mode noise picked up along the cable run between processor and amplifier — the longer the run, the more relevant this becomes. Noise at the XLR input measures -110dB; the RCA input measures less than -108dB.\u003c\/p\u003e\n\u003ch3\u003eNetwork Monitoring and Control\u003c\/h3\u003e\n\u003cp\u003eAn Ethernet port on the rear panel connects the 9B³ to your local network. The built-in web interface lets you monitor per-channel temperature, view clipping alerts, mute individual channels, power the unit on or off, and install firmware updates — all from a browser on any device.\u003c\/p\u003e\n\u003cp\u003eRS-232 serial control integrates the 9B³ with Crestron, Control4, Savant, and similar home automation platforms. DC trigger input and output handle automated power sequencing with other components in your system.\u003c\/p\u003e\n\u003ch3\u003eSoftStart and DC Trigger\u003c\/h3\u003e\n\u003cp\u003eSoftStart is a microprocessor-controlled startup sequence that ramps current draw gradually at power-on. This prevents speaker-damaging transients and stops the amplifier from tripping circuit breakers — a genuine concern with a high-power amplifier drawing large startup current. DC trigger in and out provide automated power switching with processors and control systems.\u003c\/p\u003e\n\u003ch3\u003eConvection Cooled — Fanless\u003c\/h3\u003e\n\u003cp\u003eThe 9B³ uses convection cooling exclusively. There are no fans. This means no fan noise during quiet passages in film or music. It also means no fan motors to wear out over the life of the amplifier. Adequate ventilation clearance is still required — see the FAQ below for placement guidance.\u003c\/p\u003e\n\u003ch3\u003eBuild and Finish\u003c\/h3\u003e\n\u003cp\u003eMachined and anodized aluminum chassis with a black faceplate and green LED channel status indicators.

Your processor needs dedicated pre-out connections, one per channel. From there, the 9B³ drives your speakers directly. You’ll also need speaker cables from each output to each speaker. Balanced XLR connections are recommended.\u003c\/p\u003e\n\u003ch3\u003eIs the 9B³ compatible with my speakers?\u003c\/h3\u003e\n\u003cp\u003eAt 200 watts per channel into 8 ohms and 300 watts into 4 ohms, the 9B³ handles the vast majority of home theater speakers, including demanding low-efficiency designs. Because each channel has its own independent supply, all five can run at full power simultaneously. Call us at \u003ca href=\"tel:+18009420220\"\u003e800-942-0220\u003c\/a\u003e if you’d like help confirming a match.\u003c\/p\u003e\n\u003ch3\u003eCan I start with fewer than five channels?\u003c\/h3\u003e\n\u003cp\u003eYes. The 9B³ is available in three-, four-, or five-channel configurations. If you start with three or four channels, you can add modules later. The chassis and internal infrastructure are already in place. Bryston sells individual channel modules separately for this purpose.\u003c\/p\u003e\n\u003ch3\u003eWhat is the Salomie circuit?\u003c\/h3\u003e\n\u003cp\u003eIt is Bryston’s patented input circuit, developed with the late Dr. Ioan Alexandru Salomie. According to Bryston, 12 active devices at the first gain stage act as a super-linear buffer, removing distortion and filtering EMI and RFI noise before they reach the signal path. The 9B³ is the first five-channel Bryston amp to use it.\u003c\/p\u003e\n\u003ch3\u003eWhy does modular construction matter for service?\u003c\/h3\u003e\n\u003cp\u003eEach channel module is a self-contained, removable assembly. If a channel needs repair, that module can be pulled and replaced without returning the whole amplifier. This matters over a 10-year ownership horizon. Most competing multi-channel amplifiers require a full return for any single-channel failure — the 9B³ does not.\u003c\/p\u003e\n\u003ch3\u003eDoes the 9B³ work with home automation systems?\u003c\/h3\u003e\n\u003cp\u003eYes. The built-in Ethernet interface provides a web page for monitoring and control from any browser. RS-232 serial integrates with Crestron, Control4, Savant, and similar platforms. DC trigger in and out handle automated power sequencing. Network control allows per-channel temperature monitoring, clipping alerts, muting, and firmware updates.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between the 17-inch and 19-inch versions?\u003c\/h3\u003e\n\u003cp\u003eThe 17-inch faceplate fits standard home audio furniture. The 19-inch version adds front handles and suits rack installation. A 19-inch PRO version is also available — it adds a rack-mountable dress panel and rear per-channel trim pots for fine level adjustment.\u003c\/p\u003e\n\u003cp\u003eThe amplifier electronics and specs are identical across all faceplate options. Both versions’ dimensions are listed in the spec table above.\u003c\/p\u003e\n\u003ch3\u003eWhat does SoftStart do?\u003c\/h3\u003e\n\u003cp\u003eSoftStart is a microprocessor-controlled power-on sequence. Instead of pulling full current at startup, the 9B³ ramps up gradually. This protects your speakers from the transient that would otherwise occur at power-on, and prevents the amplifier from tripping household circuit breakers — a practical concern with a large, high-power amplifier.\u003c\/p\u003e\n\u003ch3\u003eDoes the 9B³ need ventilation? Can I rack-mount it?\u003c\/h3\u003e\n\u003cp\u003eYes, it needs ventilation. The 9B³ runs warm and uses convection cooling — heat rises through the chassis naturally. Leave clearance above and around the unit. Do not install it in a sealed enclosure.\u003c\/p\u003e\n\u003cp\u003eFor rack use, leave at least one rack unit of open space above the amplifier, or use a rack with active ventilation. The 19-inch PRO version is the correct rack-mountable configuration.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003eWhat’s in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBryston 9B³ Five-Channel Amplifier — Black, 19-Inch Faceplate, Green LED\u003c\/li\u003e\n\u003cli\u003eIEC AC power cable\u003c\/li\u003e\n\u003cli\u003eOwner’s manual\u003c\/li\u003e\n\u003cli\u003eWarranty and registration documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy Audio Advisor?\u003c\/h2\u003e\n\u003cdiv class=\"ec-titlebox-text\"\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f3b5.svg\" alt=\"music note emoji\" width=\"20\"\u003e \u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e40+ Years of Expertise\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e— Since 1981, we’ve helped over a million music lovers find the right gear.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f504.svg\" alt=\"repeat emoji\" width=\"20\"\u003e \u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e60-Day Money-Back Guarantee\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e— Take your time.
