Legacy AXS API
locally switched ON or OFF via the front panel switch. An LED meter indicates output level in dBu. The
low noise floor, together with a clip point over +28dBu, makes this preamp suitable for the most
extreme applications requiring the highest quality audio.
The controls for the 212 Mic Preamp function as follows:
GAIN: Sets the preamplifier gain across a 55dB gain range
METER: The 5-segment LED meter indicates the mic pre output level in dBu
48V: Provides 48 Volt Phantom Power to the MIC PREAMP INPUT and MIC TIE-LINE patch points
• Illuminates when engaged
-20: Inserts a -20dB pad
• The level feeding the mic transformer is reduced by 20dB, while keeping the proper load on both
the mic and transformer
• Illuminates when engaged
205 Direct Input
Features
• Wide range GAIN control
• Hi-Z ¼” input, like a tube amp
• Thin < > Fat TONE Control reduces low end mud
• BRIGHT Switch boosts the presence
• -20dB PAD lowers the input level
• 100 K LOAD switch changes the tone of instruments
• 5-segment LED Meter shows output level
• Transformer coupled output to +28dBu
• All Discrete Design
The API 205 Direct Instrument Input is specifically designed to accept a guitar or
bass direct into it, without any loading on the pickups. The Gain Control is used to
normalize the instrument's input level, up to a +4dBu output level. With the use
of the unique TONE control, the low end "mud" can be reduced. Turning on the BRIGHT switch adds
clarity, like the bright switch on any amp. The combination of these two functions may eliminate the
need for any EQ on the instrument when recording, keeping the signal pure.
The input is designed specifically to load a pickup the same way that a tube guitar amp would, retaining
all of the tone, and minimizing the loading effect on the pickup. This minimal path eliminates the need
to use a standard direct box, which more times than not only converts the signal to a balanced mic
level output, which still requires a mic input, equalizer, and fader to get the signal to a recordable level.
The 205 is capable of boosting any instrument to a hefty line level without additional amplifiers. With
the 100 K LOAD switch, the tone of the pickup can be altered slightly, which tends to darken the high
frequency content. The BRIGHT switch adds a treble boost in the same manner that most instrument
amplifiers do, clarifying the instrument and adding presence to it without the need for outboard
equalization. When inserting an instrument with an internal preamp or a line level instrument such as
a sampler or a keyboard, the 205 has a -20dB PAD switch to drop the level without loading, thereby
retaining the full range of the 205 and its features.
Also, the output of the 205 can be fed to multitrack or the input of a guitar amplifier. The artist can
then be in the control room while the instrument amp is isolated in the studio. The 205 Direct Input
makes use of the 2510 and 2520 op-amps and therefore exhibits the reliability, long life, and uniformity
characteristic of API products.
The controls for the 205 Direct Input function as follows:
IN (in/out switch): Activates the module
• Illuminates when engaged
Hi-Z IN (¼” input jack): Instrument input jack
• High-impedance
