Creek Audio

The Creek Audio Sequel mk4 is a high-performance phono pre-amplifier designed to integrate seamlessly with Creek amplifiers, including the new 4040 A Integrated Amplifier. It enhances the signal from moving magnet (MM) and high-output moving coil (MC) cartridges, ensuring high-fidelity playback with optimized RIAA equalization.

Key Features

• Flexible Gain Settings: User-selectable 40dB or 50dB gain to accommodate different cartridge outputs.
• Adjustable Capacitance: Configurable input capacitance at 100pF or 200pF to fine-tune cartridge matching.
• IEC Low-Frequency Roll-Off: Selectable option to enhance bass clarity and reduce subsonic noise.
• High-Quality Components: Multi-layer PCB with mini-MELF resistors, WIMA capacitors, and low-noise LM4562 operational amplifier.
• Plug-and-Play Installation: Designed for direct integration with Creek amplifiers from 1993 onwards.
• Compact and Efficient Design: Maintains ultra-low noise and power stability through capacitance-multiplying filtering.

Detailed Description

Superior Circuit Design

The Sequel mk4 employs a multi-layer printed circuit board (PCB) to optimize circuit performance by minimizing noise and improving signal integrity. The top layer primarily handles circuit interconnections, while the bottom layer ensures power supply stability, acting as a magnetic shield against interference.

Optimized RIAA Equalization

Designed to meet the RIAA standard, the Sequel mk4 ensures accurate frequency response adjustment, enhancing clarity and detail in vinyl playback. It incorporates precision WIMA capacitors and low-noise active gain stages to maintain sonic purity.

Compatibility and Installation

The Sequel mk4 is compatible with a broad range of Creek integrated amplifiers and pre-amps, including:

• Evolution 100A, Evolution 50A, Destiny 2, Evolution 2
• Evolution 5350, Classic 5350 SE, 5350 SE, 5350 R, and 5350
• 5250, 5250 R, 5250 SE, 4330, 4330 R, 4330 SE, 4240, 4240 SE, and P42 Pre-amp

For optimal performance and safety, the Sequel mk4 must be installed by a certified dealer or Creek Audio when used with the Voyage i20. However, users can install it themselves in compatible Creek models.

High-Fidelity Performance

The Sequel mk4 integrates high-precision mini-MELF resistors and LM4562 operational amplifiers to achieve exceptionally low noise and high signal clarity. Its switchable low-frequency filter prevents unwanted subsonic frequencies, improving overall sound precision.
