HiFonics TRX4004DSP

The HiFonics TRX4004DSP from the THOR series combines powerful, sound-oriented Class A/B amplifier technology with a high-performance 8-channel digital signal processor. With an output power of up to 4 × 150 watts RMS into 2 ohms, the amplifier offers ample power reserves for demanding car audio systems.

The integrated 32-bit DSP processor allows for extensive customization of the sound system to match the vehicle's acoustics. Using the M-CONTROL 2 software for Windows, you can individually configure crossovers, equalizers, time alignment, volume levels, and phase settings. A total of eight DSP channels are available, which can be adjusted individually or in pairs.

With six RCA inputs, an additional stereo AUX input, and an optical digital input, the TRX4004DSP offers flexible connectivity options. Four built-in amplifier channels drive the speakers directly, while four additional RCA outputs allow for the integration of additional power amplifiers.

Its high-quality features include screw-mounted RCA jacks, low-noise input operational amplifiers, a double-sided laminated circuit board, and solid die-cast aluminum end caps. The illuminated HiFonics logo, the blue-illuminated heat sinks, and the illuminated connection terminals highlight the distinctive design of the THOR series.

An included wired remote control allows you to conveniently adjust the master volume and subwoofer level, as well as select input sources and saved DSP configurations.
