TK 9004
4 X 2400W Class H, Audio Power Amplifier
Product at a Glance
The TK 9004 is a robust 4-channel Class H amplifier delivering up to 2400W per channel at 4Ω and 5400W bridged, engineered for heavy-duty touring, installation, and live sound applications requiring uncompromising power and clarity. It features an over 800 damping factor at 1kHz and 8Ω for tight low-frequency control and high SPL fidelity, with a wide frequency response from 20Hz to 20kHz and THD under 0.1% for clean, transparent output. Built for operational efficiency and durability, the amplifier includes advanced protections against short circuits, DC offset, and inrush current, with user-friendly rotary volume knobs, signal limiters, LPF and sensitivity toggles, and LED indicators for real-time monitoring. Housed in a sleek black aluminum chassis with a matte star white front panel, it fits seamlessly into modern racks, operates quietly with a 32 dB fan, and supports 4 analog inputs plus link outputs, offering flexible connectivity and reliable performance in demanding environments.
CRAFTSMANSHIP
Painstakingly Perfect Production
Over the years, craftsmanship has been closely linked with small scale individualistic production. Back in 1972, we started the same way. As we grew in scale & size, it was difficult to build each speaker individually, but quality control was of utmost importance as so switching to a general assembly line was simply not an option. So we wrote up a code, one quite like enigma, to ensure quality control. We selected the right partners, got the right tools, and in cases where those weren't available, we invented them. We grew slower than most as our aim was to last longer than most.
