Information on the disposal of old devices

Phase-linear filters – no distortion

The t.racks FIR DSP 408 is a substantial improvement on its predecessor, the t.racks DSP 408, primarily thanks to its integrated FIR filters, a major advantage for anyone seeking phase-linear processing. The front end has also been extensively updated, providing a much clearer interface that makes operation significantly more intuitive, while a variety of remote control options further enhance usability. Despite these improvements, the device retains its four inputs and eight outputs, ensuring that the t.racks FIR DSP 408 remains perfectly suited for larger setups – with no compromises.

No distortion thanks to FIR filters

FIR, or Finite Impulse Response, refers to filters with a finite impulse response, offering the key advantage of linear phase so that the filtered signal experiences no phase distortion. The t.racks FIR DSP 408 provides integrated FIR high-pass and low-pass filters for all eight outputs, supporting up to 1024 taps per filter, while users also have the option to load their own filter coefficients. It's important to note that higher tap counts increase latency, with 1024 taps producing an adjusted latency of 10ms, so using more than 512 taps per filter is generally not recommended. The inputs are also equipped with FIR filters, although here only user-defined filter coefficients can be applied.

High performance at low cost

The t.racks FIR DSP 408 is a digital speaker management system that has no trouble competing with far more expensive models, offering a wide range of options for precise speaker system adjustment and signal processing, along with the benefits of phase-linear filtering. The device can be seamlessly integrated into existing setups both analogously and digitally via AES/EBU connectors, while the software included provides full access to all functions from a computer, greatly simplifying the calibration of larger systems. For added convenience over long distances, the LAN connector enables integration into a local network, and operation via Wi-Fi is possible too.

About the t.racks

The in-house brand the t.racks has been an integral part of the Thomann music store range since 1997. A wide range of different rack devices, effects, power distributors, and accessories appear under the t.racks name and prove that quality, reliability, and attractive pricing do not have to be mutually exclusive. Whether for home studios, the stage, or the rehearsal room – the t.racks offers a convincing and affordable solution for every situation.

A huge selection of options

The t.rack FIR DSP 408 comes with intuitive software that presents a clear matrix for interconnecting all four inputs with the eight outputs, while a simple visual display instantly shows how each input is routed. Designed with larger speaker systems in mind, its wide range of functions and flexible I/O options make it perfect for applications such as delay lines, side-room reinforcement, under-balcony fills and more, and with its extensive set of filters – FIR and IIR, parametric and graphic EQs, as well as high-pass and low-pass filters – the device provides all the tools needed to handle virtually any acoustic challenge.

Surprisingly good

Hellogoodbye 04.09.2020

Our engineers were surprised by the quality of this product, they work with far more expensive gear and said this is very competitive, specially for this price.
It is much more quiet than our previous dbx dsp.
We are buying a second one.

Great DSP for the money!

Oddsound 16.09.2020

Using it in my Hi-Fi setup, to electronicaly crossover and romcalibrate my biamped speakers.
FIR filter can be generated on computer and transfered.
Sounds good also as a HiFi component. No signalnoise. But the cooling-fan is making some noise in the livingroom.
