Dual transformer voicings
The United Replay Box is equipped with two distinct re-amplification circuits, Transparent and Harmonic, each featuring its own custom transformer. The Transparent circuit incorporates a US-made 5043 step-up transformer, renowned for its exceptional signal isolation and noise rejection capabilities.
This transformer is designed to provide a completely clean, uncoloured signal, ensuring that the output retains the integrity of the original recording. It accepts both balanced and unbalanced line-level inputs and delivers an isolated, unbalanced output that can drive any amp, pedal, or processor. The transformer’s passive gain offers an additional 3 dB above its +4 dB rated input, allowing for pristine signal amplification without introducing noise or distortion.
The Harmonic circuit, on the other hand, is designed for those who prefer a more coloured sound. This circuit engages an alternative transformer that adds character to the signal. It offers a steeper gain ratio and gently rolls off the upper high frequencies, enhancing the warmth and richness of the low mids. The Harmonic circuit introduces both harmonic and phase distortion, providing a fatter, more aggressive tone that is ideal for adding depth and warmth to your recordings.
Ultra-quiet design
One of the primary challenges in re-amplification is managing noise. The Replay Box addresses this issue head-on with its ultra-quiet design. When re-amping, any noise present in the signal chain can be amplified, compromising the quality of the final output.
The Replay Box’s design ensures that unwanted noise is minimised, preserving the clarity and purity of the re-amped signal. This is achieved through meticulous engineering and the use of high-quality components, which work together to eliminate sources of noise and interference. Additionally, the true ground isolation feature ensures that ground-loop hum, a common issue in re-amping, is effectively prevented. This results in a clean, noise-free signal that maintains the integrity of the original recording.
Exceptional signal isolation
The Replay Box’s custom-wound transformers are key to its exceptional signal isolation capabilities. These transformers are specifically designed to provide superior noise rejection, ensuring that the signal remains pure and free from interference. The Transparent circuit’s transformer, in particular, excels at isolating the signal and providing clean gain, without the need for additional noise-inducing preamps or boost pedals.
Built for durability
The Replay Box is not only designed for outstanding performance but also built to withstand the demands of both studio and live environments. Its robust aluminium chassis provides durability and protection against the rigours of daily use. The recessed design safeguards the unit from accidental knocks and bumps, whether in the studio or on stage.
Additionally, the screw-mounted removable feet offer flexibility for various mounting options, making it easy to integrate the Replay Box into any setup. This combination of rugged construction and thoughtful design ensures that the Replay Box is a reliable tool for engineers and musicians alike, providing consistent performance and durability over time.
