API Audio 205L Discrete Direct Input - Manual

205L DIRECT MODULE
“Thin it out and make it bright”
METER: Output Level, VU scale
BRIGHT: Brightens the high end
-20 PAD: -20 dB PAD switch for high level inputs
100K LOAD: Adds a 100K load for changing the
tone of a guitar or bass pickup (coil types)
ON: Turns ON the signal
HI-Z IN: 1/4” Hi-Z input
Guitar level to Line level
GAIN: Input Level Control
TONE: THIN to FAT
(Fat is Flat)
215L HI/LO PASS FILTER
“Schweet”
ON: Hard Wire Bypass
HI-PASS: 20 to 600Hz at 12 dB/oct
LO-PASS: 500 to 20KHz at 6 dB/oct
NOTE: The filter design is a simple passive
circuit, using the API 2510, 2520 and the
same discrete buffers used in the 550 series
EQs.
FILTERING: This filter is very gradual, at 6dB/oct for the LO-Pass filter and 12dB/oct for the HI-Pass filter. Its primary design
is intended for reducing the low-end leakage into a Hi-Hat or overhead mic, or reducing the noise and flap on a bass guitar.
Basically, it is not for “fixing” problems, but for contouring the response of a signal without the drastic curves of many EQs and
their associated phase shift.
FAT/THIN: The FAT/THIN knob is designed to take out the mud in the lower strings of a guitar or bass, evening out the
relationship of the lows to the highs. With the addition of the BRIGHT switch, you can add clarity the same way as a guitar
amp bright switch would. The input impedance is 470K ohms, like a tube amp input stage, preventing pickup loading. The
LOAD switch adds a 100K ohm load to the input, changing the tone of a coil pickup slightly.
