6. CONNECTIONS AND CABLES
6.1 Inputs
The LX-308 stereo inputs use two 10KΩ unbal-
anced 1/4" phone jacks per channel, with (+) signal on
the tip and ground on the sleeve. If you wish to drive a
mono source into the stereo mix, simply plug your signal
into the right channel input. Channels 1 and 2 are swit-
chable to accommodate signals from low impedance dy-
namic microphones.
6.2 Sub Inputs
The Sub inputs are nominal 10KΩ unbalanced
types on 1/4" phone jacks. They feed directly to the mix
busses at a nominal +4dBu level and are useful for cou-
pling multiple mixers
6.3 Sub Outputs
The Sub Outputs are unbalanced types on 1/4"
phone jacks. Typically, they will feed sub inputs on ad-
ditional mixers. Nominal operating level is +4 dBu.
6.4 Main Outputs
Outputs are 200Ω "pseudo-balanced" 1/4" phone
jacks, which means they have balanced impedance with
a single-ended signal source and can be wired balanced
or unbalanced. Nominal operating level is +4 dBu and
maximum headroom is +22dBu.
6.5 Wiring Suggestions:
If low level and high level lines (e.g., micro-
phones and mixer line outputs), or if either of these lines
and speaker cables are run parallel for long distances,
crosstalk may be significant. In fact, the crosstalk (sig-
nal leakage between cables) can cause an electronic feed-
back loop, oscillation, and possibly damage to the
equipment. To minimize crosstalk, physically separate
low level (microphone) cables from speaker cables by the
greatest feasible distance. At any point where cables meet,
run low level cables perpendicular to high level or speaker
cables. If low and high level or speaker cables must be
run parallel and in close proximity to one another, they
should be bundled separately.
