The Joemeek sixQ2 packs a wealth of features into a single rack space studio channel.
Some changes we made to the sixQ2:
>The microphone input transformer is permanently assigned to the “Mic” Input. The “IRON” switch now optionally sends the “Line” input through the transformer, to add some colouration to Line sources.
>The input “GAIN” control now operates over the range 18dB to 60dB, with improved resolution in the crucial 25dB-45dB range. Microphone inputs up to +4dBu can be accommodated without distortion
(+24dBu by using the “PAD” switch).
>As before, with the “LINE” input selected the gain is unity (0dB) at the top of the dial; the gain range is now -19dB to +22dB.
>The “INSTRument” input now has a gain range of 0dB to +40dB.
>”PEAK” LEDs now light at +16dBu (2dB below Full Scale Digital).
A single channel mic pre, three bands of highly musical EQ, and our signature optical compressor make for a highly capable recording instrument. With a front panel instrument input

Digital Output Specifications
24-bit delta sigma using Wolfson WM8738 ADC
44.1kHz, 48kHz, 88.2kHz or 96kHz selectable
S/PDIF electrical, S/PDIF Optical
This is [sample frequency divided by twice the bandwidth]. So for a 20kHz bandwidth sampled at 96kHz, oversampling = 2.4x.
However the term oversampling is sometimes confused with [clock frequency divided by sample rate]. In the DB-1 that would be 256x at 96kHz
Noise Floor: typically 92dB A-weighted (referenced to 0dBFS = +18dBu). So for a +4dBu signal, the SNR is 78dB
Distortion: typically 0.01% @ 0dBu (20Hz – 20kHz) at 96kHz sample rate
typically 0.02% @ 0dBu (20Hz – 20kHz) at 48kHz sample rate
typically 0.02% @ -1dBFS (20Hz – 20kHz) at all sample rates
typically -67dB (20Hz – 20kHz)
The Joemeek Digital Audio Interface provides high quality digital audio outputs. The digital audio outputs are compatible with most digital recorders, as well as Digital Audio Workstations and mixers. S/PDIF format is available from the RCA phono connectors.
The Joemeek Digital Interface has highly stable onboard master clocks for low-jitter, hi-fi results. Internal sample rates of 44.1kHz, 48kHz, 88.2kHz or 96kHz are selected by means of rear panel switches. 44.1kHz is the standard used for audio CD’s, while 48kHz and 96kHz are widely used in recording studios. In general, the higher the sample rate, the better the audio fidelity, but the more disk space is required for the recording. For example, recording at 96kHz requires twice as much storage as 48kHz. Consult the manual of your recorder or DAW as to what sample rates it will accommodate.
