Unprocessed multitrack going through the Interphase Audio Octa Rack with quite some Barium Reference Meter modules.
Barium is available by itself, but also gets used in the Interphase Audio Silicon, Iron and Zinc preamps.

Ark console - IP616 meter module
This module consists of 16 of our Reference Bargraph Meters, installed in the upper part of the master section, next to the group and aux master modules.

The IP616 meters can read:
* Inputs and outputs of the IP916 stereo channel module (each channel of the IP916 has meter input/output selection)
* Aux A and Aux B outputs
* Group outputs
* External Inputs
(selection is done on the IP616)

TopAmp99 ready to be shipped to a customer in the UK.
TopAmp is the finest op-amp available for audio applications, providing superior sound quality.
TopAmp is a Discrete audio operational amplifier that uses pure Class-A circuitry from input to output, designed to re-capture the clarity and character of classic audio recordings from the 1960’s and 1970’s

Derived from a long-held understanding that where sonic fidelity is concerned, “less is more”, the TopAmp uses the absolute minimum of components necessary to achieve the performance expected from a modern op-amp in terms of noise, distortion and power supply rejection.

When operated at ±24V, input and output signals of +26dBu are accommodated. Even at maximum signal level, distortion is only 0.004% and is mostly second harmonic.

TopAmp is used in the Ark console and all other Interphase Audio products, and is largely responsible for the exceptional sound quality of our products.

With the TopAmp 99 adaptor, the TopAmp can to be retrofitted to any existing audio equipment designed to accept the industry-standard 2520 / 990 footprint, upgrading that equipment with the superior TopAmp sound quality.

TopAmp and TopAmp99 are now available from our online store.

Our Series 8 prototype

Lead ...
Our Headphone Amplifier in 500 /51x series format.
Not much else like this.
If you need a headphone amp, this may very well be the way to go.
Two headphones can be connected, each with their own level control. And that's it.
We kept things simple, so Lead can be used anywhere in the studio - by engineers, singers, musicians - without anyone getting confused by unnecessary bells and whistles.
Lead gets it's sound quality from our custom, discrete OpAmps (the same as used in the Ark console and all our products)
Hook up a good headphone and be amazed.
You'll most likely hear things you've never heard before in any recording or mix you made, or any CD you may know very well.
Lead is the headphone amp which brings out the full details. Really.

Barium - Iron - Silicon
500 series modules now available

Barium is the Reference Bargraph Meter for 500 users.
20 LEDs with 42 dB scale and peak hold, calibrated for precise reading.
Available as single-channel or dual-channel module.

Silicon is the 500 module version of the much loved Microphone Preamp of the Ark console.
This preamp will amplify the signal coming from the microphone incredibly well - transparent, pristine, clear - without colouration, distortion or added noise.
Silicon brings out the best from any microphone, but can accept any signal source.

Iron is the 500 module version of the fabulous MicPre of the Ark console with our custom Input Transformer
This preamp will amplify the signal coming from the microphone incredibly well - transparent, pristine, clear - but transformer generated harmonics and distortion will be added when “running hot”. Iron brings out the best from any microphone, with that little extra “push” if needed.

Barium - Iron - Silicon are available as 500 and 51x series module with Silver or Black faceplate.

Prototyping Barium Bridge.
8 - 16 - 24 - 32 channels of reference metering in a beautiful wooden desktop box.
needs some work on the wood though :-)
