ANALOG AUDIO – UNBALANCED INPUTS

INPUT JACK CHARACTERISTICS

The XT includes eight unbalanced, phono jack inputs. These are compatible with low - impedance, unbalanced, -10 dBV outputs typical of equipment such as mixers, synthesizers, samplers, direct boxes, etc.

The unbalanced input jack wiring convention is as follows:

Signal Ground

TYPICAL INPUT JACK HOOKUPS

The input jacks are typically hooked up in one of three ways:

To the console’s direct tape outs (these patch a single channel directly to tape, bypassing most mixer circuitry). This is preferred when the signals going to tape require none of the mixer’s features (effects, grouping, routing, etc.).

To eight mixer bus outputs. You can use the mixer for grouping, premixing, effects, etc. This puts more circuitry between the input signals and XT, although since most routing can be done at the mixer, you’ll seldom need to do any repatching.

To a combination of direct outputs and bus outputs. Some situations require a combination of the two approaches. Example: Consider a live gig you want to record with two vocal mics, four mics on drums, two direct feeds from guitar and bass amps, and one direct feed from keyboards. The vocals, bass, guitar, and keyboards could be taken direct and go to five XT tracks. The four drum mics can be mixed to stereo within your mixer sent to the submix outs, then go to two XT tracks. The remaining XT track could be used to record audience sounds or capture one of the instruments in stereo, if applicable.

ANALOG AUDIO – UNBALANCED OUTPUTS

The -10 dBV outputs use RCA jacks, and carry signals at a nominal -10 dBV level. These should be connected to your mixer’s channel line inputs or tape returns. The unbalanced outputs wiring scheme is similar to that of the unbalanced inputs (see previous section).
