The Joemeek oneQ2 is the most full-featured, technologically advanced studio channel we've ever made!
Some changes we made to the oneQ2:
>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 combining Mic Pre (featuring Cinemag microphone transformers), four band EQ, the most flexible of any Joemeek ever, our "signature" optical compressor, De-Esser, and Enhancer, it's a master channel like no other.
Housed in a 2u chassis, the elegantly sculpted faceplate is intelligently laid out, with clear, easy to read legends and a large analog VU meter.
We even included 24bit, 96K A/D converters with word clock input and output.
The new oneq2 raises the bar for all studio master channels!

Digital Output Specifications
Sampling: 24 Bit
Resolution: 24-bit delta sigma using Wolfson WM8738 ADC
Sampling Rate: 44.1kHz, 48kHz, 88.2kHz or 96kHz selectable
Output Formats: AES3 compliant (balanced), S/PDIF electrical
Oversampling: 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
External Word Clock input: 75ohm, 1.25V - TTL level, 44.1kHz to 96kHz (auto synchronising)
Crosstalk: typically -67dB (20Hz - 20kHz)
The Joemeek Digital Audio Interface provides high quality digital audio outputs plus the ability to synchronize to an external word clock. 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, while the transformer coupled XLR connector provides an AES3 compatible output.
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.
Alternatively the oneq2 may be set to the frequency of an external master word clock, generated, for example, by the studio's recorder or DAW. When connected to the BNC socket provided, a suitable external word clock will be detected automatically and will override the twinQ's internal word clock.
The front panel LED labelled 'EXT CLK' illuminates when the oneq2 is successfully locked to an external word clock. To avoid distortion, care should be taken not to overdrive the input to the Digital Interface. The red LED next to the Output Gain control is labeled "PEAK FSD" which stands for "Full Scale Digital". Occasional flashes are OK but if it is on all the time, turn something down!
