- About Us
The MPL-2 is housed in a 1U 19" rack mount alloy case.
A minimum of controls is used due to automatic time constants and optimisation techniques for the gain reduction. The advantage is not only simple operation but also increased performance for highly dynamic and inconsistent materials without the need for continuous readjustments.
The input gain does not reduce the wide dynamic range of the limiter. It can be used at its maximum setting with no increased risk of distortion. This eliminates the need for excessive levels, which could cause clipping in equipment feeding the input of the limiter. A further benefit is that the maximum peak output level (set with the threshold) is independent of different gain settings.
High Frequency Limiting is primarily intended for use as a de-esser, reducing unattractive high frequencies. Part of the high frequency limiter circuit is also used to reduce distortion from the wideband limiter.
Users of the MPL-2 will notice the removal of spurious peaks, and an increase of subjective levels, without the coloration and increased distortion so often associated with soft clippers and other ultra fast limiters.
The Phoenix SB is now the standard production version of the Phoenix compressor. Alongside the now classic circuit design of the original Phoenix, it incorporates the side chain filter controls from the previous standard Phoenix SC model with the new addition of an HT standby switch.
The additional HT Standby switch allows the user to put the Phoenix into a low power standby mode that is designed to increase the life of the unit's valves and capacitors. When first switching on, or if the unit's not in use for a while, have the Standby on. Switch off Standby and it will instantly come back to full life.
We have also placed the meter zero controls on the front panel for much easier access. Both meters should read "0" when the Phoenix is off standby and not compressing. They can be adjusted easily by any user without harm to the unit.
The side chain filters can be used to cut the Phoenix's compression response to bass frequencies. The filter operates below either 150Hz or 300Hz on each channel and when stereo link is engaged the filters operate at the average of the two sides. This enables the user to choose from 5 filter frequencies when in stereo operation.
The Phoenix is well known for its smooth "soft knee" compression characteristic and excellent specifications. This means that it can be used as a compressor that will not harm your signal quality, whilst subtly controlling dynamic range. It is also possible to drive the unit harder to produce harmonic distortion and higher ratio compression if desired. Many users have found these features bring life to mixes or individual instruments, and control vocals, with a natural "warm" quality.
Contrary to the above, users have found that if the unit is operated in standby mode (it still passes audio) a "symmetrical" distortion occurs, not unlike that produced by overloading analogue tape. Perhaps this fact alongside an exaggerated compression curve lends to the Phoenix in standby mode another dimension.
