Upper Input Channel Module

The IP111 is our inline input / routing module, situated in the upper section of the Ark console, and a little over 4U high.
Like the rest of the
Ark, it is a fully discrete, class-A design and offers exceptional sound quality.
It’s designed to handle multiple sources, and to offer extended routing options for each of these sources.

Unlike most other inline consoles, The Ark features two fully independent audio paths per channel. Each of these audio paths has its own independent routing, insert, EQ, fader and auxes.

The IP111 has 3 inputs, each controlled with their own trim pot.
Like all Ark8 modules, the IP111 comes with Silver or Black faceplate (you choose).

Mic input
For pure sonic clarity, the
Ark’s transformerless, universal, solid-state Mic amp can accept signals from any type of microphone whatsoever. Even older Ribbon microphones, synths or guitars can be directly connected to the Mic input without a problem (so yes, you can also use this mic input as a line input).
With an extraordinarily low Equivalent Input Noise of -138dBu, our Mic pre will not add any noise over and above that coming from the microphone itself.
The Mic trim pot gain range has been limited from +20dB to +60dB to allow fine level control.
To allow for lower input level boost, we added a 20dB
[Range] switch, so the range can be changed to be 0dB to +40dB, keeping the same fine control of the input signal.

Note that the
[Range] switch is not a “Pad”, but changes the gain range of the microphone amplifier by modifying the following parameters:
- the value of the gain pot
- the quiescent current of the input stage
- the amount of feedback used to stabilise the circuit accordingly
All of these are necessary to preserve the exemplary noise, distortion and headroom performance at all gains.
In short: While a “pad” and our “range” have a similar effect, a “pad” adds noise to the circuit, our
[Range] switch does not

Line input
The Line input can be trimmed from -20dB to +20dB, and has centre detent.

[Line] switch selects between the external Mic or Line input.

[Phase Reverse] switch is situated after the Mic/Line selection, so phase reverses both Mic and Line input signals.

DAW input
The DAW input has it’s own trim pot with centre detent, and has a gain range of -20dB to +20dB.
Note that the DAW input is in reality another line input, so apart from return from your DAW (through your audio interface), it can also be used for any line level source or for analogue tape returns.

Audio Path
Standard (all switches out), the Mic/Line input is routed through the Small Fader (SF) path, while the DAW input is routed through the Large Fader (LF) path.

IP Rev
[IP Rev] switch reverses the signal path of Mic/Line and DAW.
[IP Rev] is active, the Mic/Line input is routed through the Large Fader (LF) path, and the DAW input is routed through the Small Fader (SF) path.

Both the SF (small fader) and LF (large fader) path have their own independent routing. This routing comes from the respective fader and pan on the lower input section (
IP311). Each of the paths can be independently send to pairs of subgroups and to 2 stereo master outputs.

Dual Inserts
Each path has its own insert send and return, standard just behind the input trim.
[Ins Post] switch moves the insert points just before the fader, post anything which may be in the middle input section (see middle input section).
[Ins On] switch activates the insert return.
Note that both Insert Sends are always active and can be used as additional pre-fader / pre- or post-eq outs or sends.

Direct Out
Each channel has one Direct Out which comes from the small fader, but can be changed to come from the large fader, using the
[Dir Out LF] switch.

All switches are illuminated.
Global Lights Dim on the master section controls the light intensity of
all switch LED’s. Turn it up if you work in a bright room, turn it down if you work in a darkened room.

To wrap up: With the IP111 input and routing module, you can route each of 3 inputs to the LF or SF path. The outputs of the faders can each be routed to 14 outputs. (subgroups 1 to 8, stereo master 1 and 2, insert send and direct out).
