color LED lightened pushbuttons for it’s functions (di , ute L/R, diff, ono) and a 3 steps
switch for setting the output.
Rearpanel:
On the rearpanel you will find 5 balanced inputs, 3 balanced outputs (2x stereo, 1x ono), a
balanced buffered pre attenuator direct output and the AC input.
Input 1 and 2 are balanced Neutrik XLR’s and input 1B, 3 and 4 have 6.3 Neutrik jack
inputs. Outputs 1, 2 and 3 and the buffered direct output are balanced Neutrik XLR’s.
Below the AC input (100 to 240VAC) you will find the 800 a fuse.
Frontpanel:
On the left side of the frontpanel you will find the headphones output and level pot eter. Next
to that you will find the AB function for input 1. In the iddle you will find the LED display and
rotary encoder. On the right you will find the 6 enlightened push-buttons.
Headphone amp:
The headphone a p is a powerful but clean transistor based a p. The a p is working pre-
attenuator which eans that the selected input is going directly into the a p and the
attenuator between 01 and 64 will not affect the signal of the headphone. When the attenuator
is set to 00, the headphone a p will be uted.
Input 1 A function
Input 1 has 2 inputs on the back of the unit. An XLR which is passive and is send directly to
the attenuator and input 1B (6.3 jack) which is first sent to the active gain co pensation
circuit. When the input 1 ab’ pushbutton is set to off (green), the passive input is used. When
the button is pressed (yellow) input 1 switches to 1b and the active circuit beco es active.
With the pot eter you can now AB between two sources with level- atched gain. The gain
range of the active gain is +/-10dB.
Rotary encoder and display
Monitor level
In the centre of the panel you will find the ultifunctional rotary encoder and the LED display.
When you turn the encoder, you will change the onitor output level with a 64 steps range.
Every step is ~1dB attenuation, 64 is no attenuation and the axi u attenuation at 01 is
approxi ately ~-64dB, 00 eans silence/ uted (also the headphone a p will be uted).
Input selector
The input selection is done by pushing the encoder, the display shows the selected input (C1 to
C4). After about 3 seconds the display reverts back to showing the attenuation value.
Balance control
When you push and hold the encoder and at the sa e ti e turn it to left or right you have a
balance/pan control. The range goes fro -9 (left) to 9 (right), centre is shown as 0.
Standby and soft start
When you push and hold the encoder for 2 seconds the attenuator goes in bypass and the
display just shows a ‘deci al dot’ and all push-switches are off. When you push the encoder
again, it co es out of standby with a soft start and shows 00 and after about 3 seconds it
reverts the last known value again (just like when powering on).
