Thank you for purchasing the DuTCH audio MC1 monitor controller. In this manual we will
explain how this device works and how to use it.
Basics:
The MC1 is a 1u 19 inch monitor-controller with durability and easy control in mind.
The MC1 is based around a passive 64 steps, 1dB per step, parallel relay-based attenuator.
Compared to a standard serial attenuator or even worse, a potmeter, a parallel attenuator
keeps almost the same impedance throughout it's complete range. This means that it's way
more transparent because of a constant load. Another plus is that because it has way less
resistors in-line, it also reduces the Johnson noise to an absolute minimum.
The MC1 has 4 balanced inputs, 2 balanced outputs, a class-A headphone amp and high
quality dual color LED lightened pushbuttons for it's functions (dim, mute, diff, mono,
monitor 1/2)
Rearpanel:
On the rearpanel you will find 4 balanced inputs, 2 balanced outputs and the AC input.
Input 1 and 2 are balanced Neutrik XLR's and input 3 and 4 have 6.3mm Neutrik jack
inputs. Both outputs 1 and 2 are balanced Neutrik XLR's.
Next to the AC input (100 to 240VAC) you will find the 1amp fuse.
Frontpanel:
On the left side of the frontpanel you will find the headphones output and level potmeter. In
the middle you will find the LED display and rotary encoder. On the right you will find the 5
enlightened push-buttons.
Headphone amp:
The headphone amp is a real powerful class-A based amp. The amp is working pre-
attenuator which means that the selected input is going directly into the amp and the
attenuator is not doing anything to the signal of the headphone.
