500 Series Tape Emulation Processor with Transformer Balanced Input & Output
The Roger Mayer 456HD-500X is a tape emulation processor in 500-series format from the British engineer, Roger Mayer. The 456 HD is a solid-state tape emulator, using a discrete Class-A ultra-high-speed analogue design to accurately simulate the harmonic and dynamic properties of the Ampex 456 used with a Studer A80 tape machine.
The Roger Mayer 456HD facilitates "high definition tape recording" - bring all of the desirable sonic advantages of analogue tape processing to your DAW with zero-latency and no tape hiss.
Transformer Balanced Input and Output
The 456HD-500 X's custom hand-wound ferrite wideband transformers are made in house by Roger Mayer and feature exceptional wide-band tonal transparency and are superior in performance to electronic balancing circuits.
These are the same transformers that are used in the Classic RM58 Limiter, Microphone Pre-Amplifiers and the new Rack Mounted 2U
Having true balanced transformer inputs and outputs enables this unit to be inserted in a DAW hard insert without any signal loss. Modern electronically balanced inputs are actually in fact differential inputs and this can cause signal level loss problems from unbalanced sources. By using both Balanced Input and Output Transformers an optimal successful interface is obtained in your signal processing chain.
Hand-built in the U.K. This is a completely discrete analogue design using only selected low-noise transistors, low-noise metal film 1% resistors, and metallised film capacitors from the world’s top manufacturers, all combined in a design to provide ultimate studio-quality audio.

B-Stock Gear FAQs
What does B-Stock mean?
In the UK you can only sell items as New if they are in their unopened, original packaging. But what happens to the items that may have been sold and returned within the purchase cool off period? They can’t be sold as new anymore because the box has been opened. It’s not new, but it’s also not second-hand, so it is then classed as B-Stock and typically priced somewhere in between. The same also applies for items that might have been scratched or dented in the manufacturing process or during delivery.
All of our B-Stock items are sold on behalf of our manufacturing partners and are under 3 month Make Noise Pro Audio warranty and in certain circumstances the original manufacturers warranty too.
All units will have been either fully tested by us in-house or a factory QC by the manufacturer where appropriate.
What advantages are there to buying B-Stock?
B-stock units are usually in "as new" condition. You get the reassurance of being a relatively unused product with the lower cost vs buying new.
Do B-Stock units have any warranty?
3 month manufacturer warranty through Make Noise Pro Audio.
