ansAmp RPM, an Overview
Simply put, SansAmp RPM is a rackmount version of our popular SansAmp Acoustic DI
pedal with the addition of a dedicated Drive control. With sweepable, semi-parametric
EQ and variable gain, SansAmp RPM offers detailed tone shaping for any signal source.

Tech 21’s proprietary, 100% analog circuitry gives your instrument a natural warmth
and presence as if you were miking your instrument through a tube pre-amp. For studio
and live applications, our SansAmp Tube Amplifier Emulation technology enables you to
go straight into the mixer of a recorder or PA system via the XLR Direct Output.

SansAmp RPM will complement any pre-amp system, particularly our own SansAmp

FRONT PANEL
SansAmp RPM is designed with
active
controls, which cut and boost, rather than
traditional passive controls which only cut. This effectively doubles many of the
control’s capabilities, giving you a much larger range of adjustability and, ultimately,
more variety. It should be noted that you need not necessarily set everything at max to
achieve maximum results. As you experiment and become familiar with the interrelation-
ship of the controls, you’ll easily be able to customize your own sounds.

Input Jack
1/4" Input is 4.7MOhm. The unusually high impedance was designed with piezo pickups in
mind to provide maximum output and dynamics. It is factory set at -20dB instrument level.
A second input jack (Input 2) is located on the rear panel. Plugging into the front Input jack
overrides and disconnects the rear panel jack. This allows you to set up your SansAmp
RPM as a permanent part of a rack or patch-bay system, with its usual input source
plugged into the rear panel jack. Then, if you want to plug straight into the SansAmp RPM,
bypassing other gear in the system, you can use the SansAmp RPM’s front Input.

Mid Shift and Mid
Mid Shift is a parametric EQ control, with a sweep ranging from 170 Hz to 3.0 kHz,

Blend
Blends the direct instrument signal with the SansAmp circuitry. In most cases, you will
probably have this set at maximum (100% SansAmp). For certain applications, however,
such as an ultra-transparent sound or for use with piezo pickup-equipped instruments,
you may want to blend-in the direct signal to achieve your desired sound. While the

Input 2 Jack
Plugging into Input 2 lets you match the SansAmp RPM’s input circuitry to the signal
level being fed into it, thereby assuring the best signal-to-noise ratio and least distor-
tion. This input is ideal for rack and patch-bay applications, especially if you use other
signal processors or multi-track recorders before the SansAmp RPM. Note: Whenever
you plug into the front panel’s Input, the rear panel Input 2 is disconnected. Also, you
can set the Input level selector switch to its -20dB position when you plug in extra-hot
signals, such as the output from active bass guitars.
