Product Description
The Joemeek twinq2 is everything you ever wanted in a dual studio channel - and then some!
Joemeek started with high quality Burr-Brown IC's for the preamp, added an extremely musical EQ section and an optical compressor for that signature "Meek" sound. Then, they included some new and innovative features, like an "Iron" switch that switches the IC front end to a transformer - completely changing the topology of the circuit. It even has 24bit, 96k A/D converters built in.
All of this comes housed in a rugged 2u chassis with a beautifully sculpted aluminum faceplate.
With sonic quality rivaling mic pre's priced thousands of dollars more, the twinq2 sets a new standard for dual channels.
Specifications
- Input impedances: Mic: 1.2kohm; Line: 10k ohm
- Pre-amp overall gain: -2dB to 60dB
- Common mode rejection: 70dB
- Equivalent input noise: -128.5dBu (unweighted)
- Distortion: 0.001% (below Compressor threshold)
- Frequency response: 10Hz to 70kHz (-3dB)
- Maximum input before clipping: Mic: +24dBu, +45dBu
- Headroom before clipping: +29dBu
- Compressor threshold: -6dBu to -22dBu (variable)
- Compressor ratio: 1:1 to 10:1 (variable)
- Compressor attack time: 1 msec to 100 msec (adaptive)
- Compressor release time: 0.1 sec to 3 sec (adaptive)
- Nominal output levels: +4dBu/-10dBv
- Output impedance: 75ohm
- Output Level switch: 12dB attenuation
- Noise Floor: -85dBu (typical, with ~40dB mic gain)
- VU Meter: Analogue movement
- Power supply: 115V / 230V ac mains, 50/60Hz
- Power consumption: 30W
- Mechanical: 482W x 88H x 220D (overall)
- Weight: 3 kilos
- High Pass Filter: 12dB per octave cut below 80Hz
- EQ Boost & Cut: +/-15dB (zero phase-shift bell response)
- LF Frequency : 40Hz to 650Hz variable
- MID Frequency : 300Hz to 5kHz variable

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)
