Instrument Inputs
Both Instrument inputs are on the front for easy access. They support high levels to
allow the connection of active or passive instruments, and they have a corresponding
high impedance. Active instruments already feature a preamp circuit, passive do not
(pickups only). Connection examples: electric guitars and basses, acoustic guitars with
pickups, double bass, etc.
Specifications:
1/4" mono jack, unbalanced (Sleeve=Ground, Tip=hot/Signal)
Input impedance: 1.1 Mohms
Maximum input level: +24.0 dBu
Frequency Response: 10 Hz - > 200 kHz
Noise: -89 dBu (unweighted, unity gain, input termination 100 kohms)
THD+N Ratio: 0.003% (at 1 kHz unity gain, input termination 100 kohms)
Note:
Low impedance line signals (DA converter,
sampler, synthesizer, etc.) ought to be con-
nected to the line inputs on the rear panel.
