Output Stage
'OUTPUT GAIN'. This output volume control provides up to 10dB
of gain and also goes right down to nothing, so acting as a fader to
fade a sound out completely.
CONNECTORS
Two outputs are provided, jack and XLR, so you can
simultaneously feed (say) a recorder and a monitor amplifier. The
switch adjacent to the 1/4" jack selects the output operating level
to either +4dBu (suits most professional studio equipment) or
-10dBv (suits semi-pro or hi-fi equipment). The XLR output is
always +4dBu. Check with the handbook for whatever you are
feeding, to find out which level is required.
The XLR output is balanced and wired as follows:
Pin 2: + (hot)
Pin 3: - (cold)
Pin 1: ground
The jack output is balanced and wired as follows:
Tip: + (hot)
Ring: - (cold)
Sleeve: ground
Balanced or Unbalanced
To run the XLR output unbalanced, it will be necessary to ground
pin 3 of the cable connector.
To run the 1/4" jack output unbalanced, just plug in a mono jack
plug. Either way, this increases the gain of the "+" signal by 6dB,
so there is no drop in level compared with balanced gear.

Digital Interface
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 optical and RCA Phono
connectors, while the transformer coupled XLR connector
provides a balanced, AES3 compatible output.
Highly stable onboard master clocks give 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.
To avoid distortion, care should be taken not to overdrive the input
to the Digital Interface. The red LED at the right hand end of the
VU Meter 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!
Note the Digital Interface is a two-channel device, with channel
one fed by the sixQ
's internal circuitry. In order to utilize the

second digital channel, an external analogue input is provided in
the form of a balanced 1/4" jack on the rear panel. In this way both
