Tech 21 SansAmp RPM

Preamp boarding the famous home Systm SansAmp Tech 21; rack version of the Para Driver DI.
For the record, it is also the-board preamp in the bass heads Landmark ddies (bottom).
This is actually the little brothers of the RBI, the less publicly known but equally good (or better?), Including the difference is a major parameter of the medium rather equalizer. It is also more oriented multi instruments, but simply to consult the manual to show how it is destiny bass.
Clearly, you like the RBI? You'll love the RPM. The connection is very complte. Lacks a mute output XLR to me, that would have triggered the silent footswitch presents dj. Also lacks a ground / lift my view, to offset another portion that would not have. The RPM is very quiet operation on the other hand.

Control:
- Drive to adjust Gain and Overdrive.
- Contrl active bass and treble to cut or increase frequency drives these ranges of 12dB.
- Equalization of parameter to medium rather of choosing the central frquence of medium rather contrle. Its operating range stretches from 170 Hz 3.0 kHz.
Contrle of the medium rather is also active to cut or increase these frquences 12dB.
- Contrl of Blend to mix the instrument signal and the signal amplifier circuit formulation lamps.
- Effects Loop with Mix 50/50 slecteur to configure the serial loop or PARALLEL.
- Between the rear jack and XLR output with adjustable levels.
- XLR output for Resort not affect the signal of the instrument alone.
- Between footswitch.
- Exit for Chan footswitch with another RPM or RBI.

UTILIZATION

Very simple configuration, the manual provided more avenues of work for those who have difficulty.
The manual is very clear.
It gets very good sounds, very quickly.

SOUNDS

It conveitn very well all kind of music. However, for sounds very modern, prfrez him the RBI. The MPR is in line oplus vintage, classic "in the ligneno metal.
The sound of the RPM is really excellent. It works wonderfully with any type of distortion (overdrive, distortion) and Fuzz.
It is also perfect to saturate the signal from any instrument, thanks to its knob drive which allows the sound to tarnish.
As with habiude TECH 21, there is presence of a high-end gear, well thought out. A true Swiss Army knife.
Direct to disk, it is a good compression coupled rgal.
The ideal is the couple RBI / RPM, whose connections are Pipelines Limited.

OVERALL OPINION

I've had it 6 months after you had a head 300 Landmark for years. I use it as prampli, I balance a Fender Bassman Fifteen TV, because its legalization is very UNESCORecords, more than the Bassman.
It allows very good bass sounds, thus typ Bassman, but Ampeg Vintage.
If he had a mute output of DI, I shall have made a good 10 to 10, but I am forced to "punish"
