In the world of professional recording, the EQP-1A is one of the most admired equalizers you’ll want to hear ever, and the all-tube EQP-1A is beloved by recording and mastering engineers for its almost magical ability to pass it almost Can improve the sound of any signal.

    RCKODLE After extensive research and development, the RCK-518 captures the essence of the EQP-1A and includes it in the compact and popular 500 series format. The RCK-518 retains the original EQ section design, control layout and beautifully smooth musicality intact.

    The RCK-518 uses a self-developed output transformer, as well as Wima and nichicon audio-specific capacitors. In addition to the EQP-1A’s classic EQ circuit, layout and exceptionally pleasant sound.

   The RCK-518 also offers fully balanced, noise-free performance and modern impedance specifications for easy operation and quick studio integration. The amplification part is achieved through the use of a 1731 module Class A amplifier, adding a slightly unique and modern twist to the classic design of the past.
