PSB CS 500W Digital Subwoofer Amplifier at Vinyl Sound Toronto Canada

The CS 500W is a 500-watt digital subwoofer amplifier from PSB Speakers (Pickering, Ontario, Canada), available at Vinyl Sound in Toronto, Canada. Designed specifically for PSB's CustomSound passive subwoofer range, the CS 500W delivers 500 watts of Class D amplification to drive up to two PSB passive subwoofers simultaneously from a single 1U rack chassis. An integrated DSP provides both pre-configured EQ profiles tailored to specific PSB subwoofer models and adjustable sound mode presets for movies, music, and flat response. A front-panel LCD and rotary encoder allow in-situ configuration, while IR input with up to four selectable channels, 12V trigger, auto signal-sensing standby, and daisy-chainable RCA outputs give CI installers full control system integration. Compatible PSB passive subwoofers include the CSIR SUB In-Room Subwoofer, CSIW SUB10, and CSIW SUB28.

500W Class D Amplification and DSP Speaker Profiles

The CS 500W's Class D amplifier topology delivers 500 watts at 4 ohms, providing the headroom required to drive demanding passive subwoofer designs at full output without compression or thermal throttling. The integrated DSP performs two distinct functions: it allows the installer to build and store custom EQ calibration profiles matched to the specific subwoofer model and room conditions, and it provides pre-configured speaker profiles that are factory-tuned for individual PSB passive subwoofers including the CSIR SUB and CSIW SUB28. These factory profiles eliminate the need for manual EQ optimisation on PSB-to-PSB system builds, significantly reducing commissioning time. Three DSP sound mode presets — movies, music, and flat — allow the system to be switched between content-optimised playback curves without re-entering the configuration menu. A front-panel LCD display and rotary encoder provide direct access to all DSP parameters, and the DSP controls can be locked to prevent accidental changes after commissioning.

Built-In Limiter, Multi-Mode Power Control, and Rack Integration

The CS 500W includes a built-in limiter circuit that monitors the incoming signal continuously and prevents the amplifier from driving connected subwoofers beyond their safe operating parameters, protecting both the amplifier output stage and the driver voice coils during prolonged high-output use. The amplifier can be powered up through auto signal sensing, which activates the amp from standby when an audio signal is detected, or via a 12V trigger input for integration with AV processors, control systems, and receivers that support trigger-based power sequencing. The stereo RCA output allows the CS 500W to daisy-chain to additional subwoofer amplifiers in the system, triggering all downstream units simultaneously via the 12V trigger chain. The CS 500W ships with a removable rack ear kit for 1U rack installation and removable feet for shelf placement, giving the installer flexibility in how the unit is integrated into the equipment rack or AV furniture.

Frequently Asked Questions

What is the PSB CS 500W?

The PSB CS 500W is a 500-watt Class D digital subwoofer amplifier from PSB Speakers, designed to drive up to two PSB passive subwoofers simultaneously from a single 1U rack chassis. It features an integrated DSP with pre-configured EQ profiles for specific PSB passive subwoofer models, three sound mode presets, a variable low pass crossover from 40 Hz to 250 Hz, a built-in limiter circuit, and comprehensive control system integration via IR input, 12V trigger, and auto signal-sensing standby. It is the recommended amplifier pairing for the PSB CSIR SUB, CSIW SUB10, and CSIW SUB28.

How does the PSB CS 500W compare to the Crown XLS 1502 and Parasound ZAMP v.3 for subwoofer duty?

The PSB CS 500W, Crown XLS 1502, and Parasound ZAMP v.3 are all compact power amplifiers used in custom installation subwoofer applications, but they serve different use cases. The Crown XLS 1502 is a high-power two-channel amplifier primarily targeting professional audio and live sound applications, without subwoofer-specific DSP or PSB speaker profiles. The Parasound ZAMP v.3 is a low-power stereo amplifier suited to distributed audio rather than high-output subwoofer driving. The CS 500W differentiates through its purpose-built subwoofer DSP, factory EQ profiles for PSB passive subwoofer models, DSP sound mode presets, built-in limiter protection, and full control system integration with IR and 12V trigger, making it the most complete single-box solution for PSB CustomSound passive subwoofer installations.

What PSB passive subwoofers is the CS 500W compatible with?

The CS 500W is designed to drive any PSB passive subwoofer and includes factory-configured EQ profiles specifically tuned for the CSIR SUB In-Room Subwoofer, CSIW SUB10 In-Wall Subwoofer, and CSIW SUB28 Dual 8-Inch In-Wall Subwoofer. These profiles are pre-loaded and eliminate the need for manual EQ optimisation on standard PSB system builds. The CS 500W can also drive PSB passive subwoofers without factory profiles using its custom EQ calibration function, and it is capable of driving other compatible passive subwoofers from third-party brands at 4 ohms nominal load.

What is the difference between LFE input mode and stereo input mode on the CS 500W?

In LFE input mode, the CS 500W connects to the dedicated subwoofer or LFE output of an AV receiver or processor using a single RCA cable to the left RCA input, and the CS 500W's internal crossover is set to the LFE pass-through position. This is the standard connection method for home theatre systems with an AV receiver that handles bass management internally. In stereo input mode, both RCA inputs connect to the line-level outputs of a preamplifier or integrated amplifier that lacks a dedicated subwoofer output, and the CS 500W's variable crossover (40 to 250 Hz) is used to filter the signal before it reaches the subwoofer drivers.

Can the CS 500W be integrated with a whole-home control system?

Yes. The CS 500W supports IR input with up to four selectable IR channel assignments, allowing it to be controlled by IR-based whole-home automation and control systems such as those from Control4, Savant, Crestron, and URC. The 12V trigger input provides power-on sequencing with AV receivers and processors that support trigger outputs. The stereo RCA output allows the CS 500W to daisy-chain a signal and 12V trigger to additional CS 500W units in multi-zone or multi-subwoofer installations, enabling all amplifiers to power on simultaneously from a single trigger event.

Does the CS 500W need to be installed inside the wall alongside the passive subwoofer?

No. The CS 500W is designed to be installed in the equipment rack alongside the AV receiver, processor, and other source components. Speaker cable runs from the CS 500W's terminal block output to the passive subwoofer in the wall or room. For in-wall subwoofer installations such as the CSIW SUB10 and CSIW SUB28, PSB recommends using in-wall rated speaker cable rated to local building code standards, with 10 AWG cable appropriate for longer runs to minimise resistance losses at 4 ohm loads.
