Advanced hub for Mid-Side processing and creative imaging
MCAudioLab LUNA Vari-Amb is a fully analog ambient processor and Vari-Amb is for Variable Ambience. You can manipulate a stereo sound landscape by two mono audio channel: the Mid and the Side.
The stereo technique is the first and the most popular you came in mind but, inside LUNA, the audio path is converted into two independent channels called Mid and Side. The Mid-Side technique is often used by engineers because of it’s own flexibility on keeping separately two main information concerning a stereo image: the sound source and its early reflections the ambience generates.
LUNA frontpanel controls
Three main sections: INPUT, ENHANCE and CONTROL. On the left side are located some toggle switch that basically change the signal path inside the processor.
The INPUT section shows up four controls as in a standard Mid/Side matrix. Each Mid and Side are furtherly splitted into two controls: the input and the trim. This topology allows you exactly reproduce the L/R scenario in M/S technique.
The ENHANCE section mainly features two knobs labeled MONO and DEPTH. These Two very controls are the processor’s core.
MONO and DEPTH simply act on the correlation held in the Mid and Side information:
The Mono enhances the monophonic information. Actually the Mono control puts into the foreground the monophonic message of the stereo track.
The Depth control gives the 3th dimension to the stereo track we are processing. For a more flexibility, two simple 3 band EQ act on each Mono and Depth control. Left sided on each EQ you find a switch that invert the phase of Mono and Depth. One each control.
The CONTROL section counts three knobs: SWAP, BALANCE, MASTER OUTPUT.
The SWAP (Share With Analog Processor) allows you to share the Mono and Depth controls with the internal processor. If the two output channels have different level, after your knob setup, you may want to balance them acting on the knob: BALANCE.
Next to the Balance is the MASTER OUTPUT that is an active main output control providing gain when hard clockwise (MAX).
The unit features two independent insert points: one for the Mid and one for the Side channels. Two toggle switch lte the unit working in insert mode. Two LED – between the two insert switches – labeled H and L blink at the same time when the return level matches the send one. The unit allows two different input mode: Stereo (L-R) or Mis/Side (M-S) just acting on the switch inside the “input” square.
An (hard) BYPASS switch forces the unit (when on) to be cutted away from the signal path.
Connectors type on the back of the unit:
XLR sockets for the input signal in L-R or M-S mode.
XLR plugs providing the output in L-R mode only.
A (post-fader) Mid – Side output on 1/4″ TRS Jack.
A complete insert matrix for both Mid and Side channels on 1/4″ TRS Jack.
