QUICK START INSTRUCTIONS
Here’s how you can get your Bass Power Engine up and running before you read the entire manual. By not reading the entire manual, however, you’ll miss out on how to get the most out of your new investment!
1. Plug your amp or pre-amp/processor output into the XLR input (preferably) or 1/4” input of the Bass Power Engine.
2. Be sure your amp or pre-amp/processor is already turned on. (See “Noteworthy Notes” #1: Powering Up and Powering Down.)
3. Be sure the volume of the Bass Power Engine is turned down. Attach the AC cord to the Bass Power Engine, plug it into a wall socket and turn the Bass Power Engine on.
4. Adjust the volume and play your bass. If you do not hear sound through the Bass Power Engine, check that all volume controls are turned up, recheck your connections, and be sure your cable isn’t faulty. If there is still no sound, refer to factory or qualified technician.

TECH 21, THE COMPANY
Tech 21 was formed by a guitarist possessing the unusual combination of a trained ear and electronics expertise. In 1989, B. Andrew Barta incorporated Tech 21 and made his invention commercially available to players and studios around the world. His highly-acclaimed SansAmp™ pioneered Tube Amplifier Emulation in professional applications for recording direct and performing live, and created an entirely new category of signal processing. While there have since been many entries into this niche, SansAmp continues to maintain its reputation as the industry standard.
After developing a full line of SansAmp models, Tech 21 expanded its offerings to include effect pedals; a compact, battery operable MIDI footcontroller, the
MIDI Mouse;
as well as “traditional” style amplifiers for guitar and bass. Each product is thoughtfully and respectfully designed by B. Andrew Barta himself with the player in mind.
Our goal is to provide you with flexible, versatile tools to cultivate, control, refine and redefine your own individual sound. Tech 21 takes great pride in delivering consistent professional quality sound, studio to studio, club to club, arena to arena.

BASS POWER ENGINE 60, AN OVERVIEW
Like most Tech 21 products, the Bass Power Engine 60 is designed to be multi-functional. For studio and live applications, it can be utilized as a pre­amp amplifier system and as a personal monitoring system.
These rugged cabinets are compatible with any direct recording device or pre-amp, analog or digital, tube or solid state, in stomp box or rackmount for­mats, from any manufacturer! (We are, of course, partial to SansAmp, but, hey, that’s just us.) Now you can take all those great direct recording sounds you’ve spent so much time creating out to a gig without having to tweak all of your presets. Simply plug your SansAmp or pre-amp du jour into the Bass Power Engine, and run the XLR output to the house P.A. You can amplify all your personal settings without getting any additional coloration --just volume. You can even take this set-up into the studio and take advantage of employing various miking techniques.
As a live stage monitor, you control what you need to hear. We’ve even included convenient, 3-band active EQ controls to compensate for difficult rooms. Ground independent inputs and output allow you to endlessly chain Bass Power Engines together --even in stereo. There’s no limit to how many you can have --for yourself, your drummer (who will most certainly appreciate the individual level control), or whoever else would benefit from being able to hear you.

THE INS AND OUTS
1/4” INPUT
Accepts 1/4” output of your pre-amp/processor or amplifier. This specialized input features an isolation transformer to eliminate ground loops when using the Bass Power Engine in conjunction with an amplifier. Be aware that this transformer loads down passive pickups. If you would like to plug your instrument directly into the Bass Power Engine, either use an active guitar or any buffered type of effect pedal (Boss®, Ibanez®, Tech 21, etc.) in bypass mode in order to drive the low input impedance of the cabinet.
WARNING: Do NOT connect the speaker output of ANY amp to the Input of the Bass Power Engine, or damage may occur.
XLR IN
Balanced XLR input accepts XLR output of your pre-amp/processor or amplifier. This spe­cialized input is also linked to the isolation transformer to eliminate ground loops when using the Bass Power Engine in conjunction with an amplifier or chaining with additional Bass Power Engines.
NOTE: If you have a choice, we recommend utilizing the XLR output of your pre-amp/ processor or amp into the XLR input of the Bass Power Engine. The only difference between the two inputs is that the XLR balanced lines provide increased hum rejection. Additionally, we advise against using both inputs at the same time.
XLR OUT
Balanced low impedance XLR parallel output bypasses the tone controls. For live gigs, you can use this output directly into the P.A. system so you won’t need to mic the Bass Power Engine.
GROUND LIFT
Connects or disconnects the ground between the XLR output of the Bass Power Engine and the mixer. We recommend starting with the ground lifted. If necessary, connect the ground by pushing the button in.

TONE SECTION
LOW, MID, HIGH
Boost or cut ±12dB from the center point (12 o’clock). Low is 80 Hz. Mid is 1kHz. High is 3.2 kHz.
These convenient, on-board
active EQ controls cut and boost, rather than traditional
passive controls which only cut. This gives you greater control over a larger range of adjustability to compensate for virtually any venue.
Be aware that you need not set everything at max to obtain maximum results. (See “Noteworthy Notes” #3.)
NOTE: Tone controls only affect the power amp and speaker, not the XLR output. The signal going into the 1/4” input or XLR input passes straight through. So you can tailor your stage sound to the room without affecting the sound out of the P.A.
ODDS AND ENDS
LEVEL
Adjusts the volume level of the Bass Power Engine. (See “Noteworthy Notes” #4.)
SPEAKER

NOTEWORTHY NOTES & CONSIDERATIONS
1) Powering Up and Powering Down. To avoid the typical loud pop and
potential harm to the Bass Power Engine speaker, power up in this order:
For Mono Applications: 1st: Amp or pre-amp/processor
2nd: Bass Power Engine 60
Power down in reverse order.
For Stereo Applications: 1st: Stereo processor
2nd: Amp or pre-amp/processor 3rd: Bass Power Engine 60
Power down in reverse order.
With PA System: Be sure to keep the PA volume fader down until all connections are made and everything is turned on. Before shutting anything off, remember to turn the PA volume fader down.
2) Hum. If nothing is plugged into the input of the Bass Power Engine, you may notice a slight hum caused by the open input transformer. When you plug something into the input, the circuit will be completed and the hum will disappear.
3) EQ. We recommend starting with all controls flat. Then use each sparingly as
needed for whatever room you’re in. Remember, you need not set everything at max to obtain maximum results. It would be rare that turning all the tone controls up would accomplish a favorable sound. In most instances, a slight cut of the Mid control should be adequate.
4) Volume. When chaining the Bass Power Engine with an amp, be sure to set the Level control to match (approx.) the output volume of the amp. If the Bass Power Engine is set higher than the amp, it may cause undesirable distortion. Note: Rely on your ears. The position of the level knobs of the amp and Bass Power Engine may not necessarily be the same.
5) Enjoy!
