Then there's the MIDI In, which accepts the Z-9 for use as a simple MIDIfootcontroller or any other MIDI footcontroller. Finally, the preamp is equippedwith a stereo jack that takes a dual footswitch, allowing you to switch the fourchannels remotely.

    Among the hallmarks of this fine preamp are painstaking workmanship and finishingas well as rigorously tested and carefully selected quality components. You'll findguidelines on care and maintenance of tube amps on page 24. Under the heading Tipsfrom the designer, you'll come across practical tips on the aforementioned featuresthroughout the manual. All critical information concerning the operation of thispreamp is preceded by "NOTE", "CAUTION", "Read and heed" or some other eye-catching comment.

  • Front Panel FeaturesAt the back of the manual, you'll find fold-out diagrams of the front and rear panels.As you're reading the descriptions of the preamp's features, you'll gain a betterunderstanding of the topic of discussion if you unfold and refer to them as we go!

    This option comes in handy when you want to insert another preamp or an effectprocessor into a serial loop along with the ENGL Preamp 570. If the other preamp canalso be bypassed, you can switch between the two preamps on the fly or even runthem both at the same time. If you want to connect a second preamp, insert it into thestereo effects loop and set the Preamp Defeat status and FX Loop status active whenyou want activate the second preamp. You could even daisy chain several preamps oreffect processors.

    Clean channel Gain control. This knob determines the preamp's input sensitivity inClean mode; use it to set the desired input level.

    The amount of distortion depends on your guitar's pickups and the Gain Boost (3)setting. In Clean mode, single-coil pickups may begin saturating the preamp when theknob is set to about the two o'clock position; pickups with very high output levels(humbuckers or active pickups) will evoke mild overdrive at even lower settings. If youwant squeaky clean tone, simply back off the Gain knob accordingly.

    Boosts the input sensitivity of Main Channel 1, and . The red LED abovethis button lights up to indicate is on. can also be switched viaMIDI program change command or the Custom Z-9 Footswitch.

    As its name would imply, serves primarily to up Clean and Crunch channelinput levels, extend both channels' gain ranges. In effect, this feature gives you twoadditional variations on these two channels' basic sounds. For example, you could setthe Clean channel Gain knob to the highest setting at which your guitar signal remainsdistortion-free, just under the preamp clipping threshold. Then when you activate

    , you will overdrive the Clean preamp slightly, yielding a grittier tone well-suited for rock riffs.Another Clean channel option is to use the as a volume booster. To do this,activate and dial in a Clean Gain knob setting, making sure not to push thepreamp into clipping zone. Consider this your high-volume clean tone, say for cluckinglead lines. Switching off gives you a softer clean tone for chord work.Switch back and forth between the two as desired.
