Fit two links in the positions K2 and K3.
5a Exchange the 125mA fuse for a similar type rated at 63mA.
For conversion to 230Volt AC (previously set to 115Volt AC)
4b: De-solder and remove the two links marked K2 and K3.
Fit a single link in the position K1.
5b Exchange the 63mA fuse for a similar type rated at 125mA.In both cases:
6: Replace the power supply using the four screws.
7: Ensure the jumper connector (P2) is correctly aligned.
8: Replace the top cover using the seven screws.

CONTROL DESCRIPTION
Both channels of the MX50 are identical and may be used completely
independently or linked for stereo operation. In the linked mode, only the left-hand
channel controls are functional and serve as master controls, though the channel
bypass switches remain independent. In linked mode, both de-essers of the two
channels track together to avoid the inevitable image shifting that would occur if the
stereo signal were treated independently.
FREQUENCY
Variable frequency from 800Hz to 8kHz covers the full sibilant range, including
hard sounding harmonics and other side effects which can be generated when
treble frequencies are boosted or enhanced in some way to brighten lower
frequencies. This control should be set to the same frequency - or centre of the
unwanted frequencies - as the esses' in the signal being processed.
DE-ESS
This rotary should be treated as a more' control. It determines how much gain
reduction is applied at the chosen frequency, up to a maximum of 20dB, which
could be very noticeable in broadband mixes.
NOTE: that this control uses floating threshold circuitry which removes the need for
a De-Ess Threshold. So, during a quiet passage, the sibilants will be held to a level
which matches the quieter original signal.
GR DISPLAY
When the signal peaks are close to that of the Frequency control, the amount of
gain reduction taking place will be displayed on the LED meter: governed by the
position of the De-Ess control.
AIR
The AIR switch allows frequencies above the sibilant band to be retained during
De-Essing, thus preserving upper harmonics and increasing the transparency of
operation. Normally we would recommend leaving this switch depressed (In).
De-Ess Band
FULL
Full band operation will reduce the total signal level in response to signals in the
selected frequency band. This mode of operation will produce less phase shifting
of broadband material and single vocals.
SPLIT
Split band operation will only reduce the selected frequencies of the processed
signal, leaving lower frequencies as they were. This is particularly useful for
