Rack 500 Dual

Zähl 500 series desktop case with external PSU. The environment we would like to operate our 500 gear in. 

IM1

Stereo I/Os, insert with dry/wet and Mid/Side option, stereo base control, in the space of two 500 series modules.

EQ1

Zähl EQ from the state-of-the-art mixing console AM1 in the API 500 Format.

A1

The A1 is our first analog input/output only product. A state-of-the-art microphone/line pre-amplifier with a de-esser in the popular API 500 Series format. The side-chain of the de-esser uses a DSP – unique but advantageous for the precision of the side-chain and enabling the use of a very low noise gain element. Two modules can be side-chain linked for stereo operation.

AFI1

The AFI1 is a no frills digital only Firewire interface. 24 channels of digital I/O in a 1 HU unit. No A/D or D/A.

DAC2

The DAC2 is based on the renowned DICE Firewire chip of the TC Applied Technologies company on the digital side and on the equally well received Burr Brown D/A converter chips on the analog side. The combination leads to a flexible and very good sounding D/A Converter.

DAC1-MK3

The DAC1 is our flagship stereo D/A converter used for highest quality D/A conversion. The MK3 version uses one of the latest DAC chips on the market in conjunction with eight discrete operational amplifiers of our own design. The MK2 version is based on our proven class A design using high performance op-amps and discrete output stages. Both DAC1 versions deliver incredible transparency – the main objective in our designs.

ADC2

Two channel A/D conversion with Line/Mic inputs and AES/EBU/Firewire output – this summarizes the ADC2’s main capabilities, but doesn’t tell much about its stellar sonic quality and its plethora of features.

SFC2

The SFC2 is a versatile sampling frequency converter with two completely independent stereo converters in a single 19 inch (1HU) unit. A SFC basically consists of a high order, linear phase, digital low pass filter. With the proper design of that low pass filter the quality of the SFC process can be made “arbitrarily” good – independent of the conversion ratio. Like what we achieved in the SFC2.

DNA1

The Weiss DNA1 is an extremely versatile toolbox for restoration work. It handles broadband noise reduction as well as de-clicking and de-crackling. The K-Stereo Ambience Processor brings back life to the music in case it lost some during de-noising, or generates a pseudo stereo signal out of mono. Finally an M/S matrix allows to define the stereo width.
