PSB Speakers CS 500W Digital Subwoofer Amplifier

The new PSB Speakers CS 500W Digital Subwoofer Amplifier is designed for the optimal control of passive subwoofers in the custom installation sector. This is suitable for both stereo and home cinema and has been developed primarily for the new PSB Speakers PWM series and the new PSB Speakers CSIR SUB in-room subwoofer.


Subwoofers are indispensable for a surround system and thus home cinema, but they can also be very useful in the classic stereo range, especially if the actual speakers are of a more compact nature and therefore require some support in the lowest bass range. Such a configuration is often found in the field of custom installation, where loudspeaker systems have to be integrated as unobtrusively as possible into the living environment, be it in the form of ceiling and wall speaker systems or wall mounting systems. Although all these solutions often show a consistently appealing performance, an additional subwoofer for the lowest frequency range does not harm the design.

Accordingly, specialists in the field of custom installation offer solutions that have been specially developed for discreet integration into the living environment, such as the Canadian company PSB Speakers, which is now also launching a matching subwoofer, the new PSB Speakers CSIR SUB In-Room Subwoofer, in conjunction with the presentation of the new PSB Speakers PWM series.

It is noticeable that the PSB Speakers CSIR SUB In-Room Subwoofer is a passive subwoofer, so it requires suitable electronics, and of course PSB Speakers has the right electronics at hand, namely the new PSB Speakers CS 500W Digital Subwoofer Amplifier.

With the PSB Speakers CS 500W Digital Subwoofer Amplifier, PSB Speakers is presenting the appropriate electronics, first and foremost for the new PSB Speakers CSIR SUB In-Room Subwoofer, a class amplifier in the form of a 1 U 19″ rack mount. This solution delivers a whopping 500 watts and also provides all the DSP-based signal processing needed to optimally drive two passive subwoofers at the same time, and to adapt their reproduction to the individual room conditions in the best possible way.

The manufacturer itself refers to the new PSB Speakers CS 500W Digital Subwoofer Amplifier as a 500 Watt Digital Subwoofer Amplifier, which, as described, can drive not just one but two passive subwoofers.

Most importantly, the PSB Speakers CS 500W Digital Subwoofer Amplifier offers DSP-based signal processing that performs two tasks. On the one hand, EQ Calibration Speaker Profiles can be created, and DSP Profiles can also be used to influence the playback according to the source material, be it movies, music or simply neutral.

The user is in control via a display on the front, next to which a rotary encoder can be found.

However, these control options are only needed for configuration anyway; for daily operation, more complex control solutions are probably required. For this purpose, the new PSB Speakers CS 500W Digital Subwoofer Amplifier is equipped with all relevant interfaces, including an IR input with up to four selectable IR channels, as well as a 12 V trigger connection. Of course, this solution has an auto standby function and both low level inputs and outputs are available on audio connections. The connection to the subwoofers is made via Terminal Block Speaker Connectors, which are common in the Custom Installation segment.

“Together with our other CS-Subs, the new PSB CSIR SUB and its dedicated amplifier offers the professional system designer numerous design and application options for solid low frequency performance. Our goal was to create a powerful sub amp that could drive up to two of the new models simultaneously, and with a series of pre-calibrations for each of our subwoofers, we were able to ensure much better tuning. The subwoofer will take much less time to install and will be much more compact and precise. This will create enormous synergies with our new subwoofers and amplifiers.”

As mentioned above, the new PSB Speakers CS 500W Digital Subwoofer Amplifier is a 19″ device, but the rack ears can be removed and placed on the included feet instead.
