In Auto Fast mode the compressor can be very fast, but only when it is really needed. German company Elysia clearly feel that compressors should be able to do far more than simply smooth out level fluctuations, and their Mpressor stereo compressor, reviewed, here aptly demonstrates this. As you'd expect from a compressor of this calibre, the bypass switch links the input directly to the output for a true hard bypass. Even the sidechain and power supply use discrete circuits. Its discrete audio path running in constant class-A mode combines a clear and open sound with a good lot of punch. This straightforward resolution saves the company both time and money, and promotes goodwill to customers.
Sidechain Filter A tunable low cut filter in the sidechain of the xpressor 500 avoids overcompression and pumping when there is a lot of low end energy in the mix. Stereo buss compression, processing single signals, approaching dynamics in creative ways — the xpressor shines in many different applications. This means that it will not affect the the audio signal itself, but the way in which it will be compressed. It seems odd that on a compressor of this sophistication there's no way to check on the levels passing through it — although it has so much headroom it is unlikely to overload before anything else in the chain. Its low distortion, ultra-transparent circuitry makes it perfectly suited to mastering and mixing in the traditional sense, while those weapons-grade extras make it invaluable for beefing up drums or bass — or just about anything else you want to energise. With its many unique features taken from Elysia's flagship products, you not only get great compression, but an amount of control on processing which is hardly ever experienced elsewhere. No matter if you want to set and forget or plunge deep into the secrets of compression, the xpressor 500 is for you.
Sidechain Filter: A tunable low cut filter in the sidechain of the xpressor avoids overcompression and pumping when there is a lot of low end energy in the mix. However, after many experiments we managed to create a smooth, anodized panel with all the details reflecting beautifully in changing light. Original and compressed signals can be crossfaded by using a mix stage, which provides onboard parallel compression. And what makes it even worse is that your mix can start to pulsate in the beat of the kick — cool for some electronic music, but certainly not always welcome. If the input level dropped below this limit, the fader would be moved up correspondingly.
For example, if a very short attack time is chosen, the compressor can catch the short peaks, but the sustaining signal will also be processed, which might result in audible distortion. The hardware alpha compressor is coveted for its professional dynamics processing, featuring innovative functions and absolutely uncompromising sound quality. Because the circuitry uses a feed-forward design based on monitoring the compressor's input rather than its output , it is also possible to set negative compression ratios expansion , which may be used to create seriously over-the-top compression effects. The designers claim to have made this equaliser sound more extreme than usual, yet only two knobs are needed to operate it. It's a switchable, semi-automated attack based on the value you set by ear. The unit offers oversized power supplies, incremental and encapsulated conductive plastic potentiometers with detents, internal heat sinks for critical components and four torodial transformers.
Afterward, the attack time automatically returns to its original setting. This function is basically a slew rate limiter that reduces the speed of the output amplifier stages. Features: Discrete Class-A Topology: As a true elysia specialty, the audio path of the xpressor is completely based on discrete circuitry and does not use any integrated circuits at all. ¢ 1:ˆž - After crossing the threshold, the output signal is constantly held at the threshold level without reacting to further increases at the input limiter. The xpressor has a low cut filter with a selectable frequency which is located in the sidechain. Warm Mode The xpressor 500 offers a second switchable sound flavor by altering its frequency spectrum, harmonics, and transient response. The class-A output stage is a low-impedance, high-current design, able to drive long cables without loss.
To get the best from the less obvious features requires a little experimentation, but the manual provides some clearly illustrated examples of different settings and goes into some detail to explain how and why they work. In other words, it boosts the high frequencies beyond the user-adjustable centre frequency and cuts the low frequencies at the same time, or vice versa. Compression can be exactly on time or totally against it, which can of course be varied on the fly. Contact one of our Audio Consultants for more details. No matter if you are a musician, producer or engineer maybe everything at the same time , we are sure that you will find truly useful solutions for your everyday work in our portfolio. This allows mid-level signals to be compressed quite heavily without reducing the dynamic range of very quiet or very loud signals. The creative options are almost infinite.
Auto Fast Inspired by Elysia's flagship compressors: Auto Fast enables you to set the perfect attack. So the range of compression that can be coaxed out of the Mpressor goes from the mild but precise dynamic-range control needed during mastering to extreme dynamic envelope modification and deliberate pumping effects. Longer settings reduce distortion significantly, but then the compressor is set too slow for catching fast impulses. In this way the xpressor 500 offers two different sound characters at the push of a button: the powerful transparency of the discrete class-A circuitry and the saturated richness of the Warm mode. The clearly laid out functions get you going straight away, while the extended features let you treat dynamics like never before. You don't want a one trick pony, but a flexible machine that covers all the standards and then some. External Sidechain: The external sidechain enables the compressor to control its processing totally independent from the audio material running through it.
And what makes it even worse, is that your mix can start to pulsate in the beat of the kick-cool for some electronic music, but certainly not always welcome. This means that no matter how high the input level might become, the amount of gain reduction will never exceed the value you've set. Hectic flicker indicates that the actual value must be somewhere in between. No matter if you want set-and-forget, or to delve deep into the secrets of compression, the xpressor 500 is for you. Elysia announced its debut product, the Alpha compressor, a high-end device designed for mastering and recording applications. If, for example, a duplicate of the input signal is processed with an equalizer and then fed into the sidechain input, the result will be frequency-dependent compression.
Where more brutality is appropriate, the Auto Fast button jumps on the fastest of transients, and in combination with high ratios this can be quite dramatic. Auto Fast Attack: Perfect attack in any situation. All components are of the highest grade available and exclusively chosen according to their sonic excellence. This means that the transistors are always conductive, resulting in the absence of crossover distortion and providing a pristine sonic base: the general sound character is always wide, open and punchy. Discrete Class A Topology A true elysia specialty, the audio path of the xpressor 500 is completely based on discrete circuitry and does not use any integrated circuits at all to color the signal path. The amazing 3D structured surface of this special aluminum was never meant to be used for front panels of high grade audio equipment, as the beautiful patterns it shows are the result of gigantic buzz saws used to cut the massive blocks into big slices. The compressor reduces the signal quickly and prevents it from slipping through.
