User Manual

Flash-Memory:

All data for the MIDI presets reside in a state-of-the-art serial flash memory chip.

This technology has the advantage that it stores information without requiring a

power source, which of course means it doesn't need a battery to do its thing.

The data required for the optoelectronic components' control algorithm as well as

the serial number of the preamp are also stored in the flash memory.

Hi Speed Preset Select mode:

Ultra-fast scrolling option for selecting presets via UP or DOWN when you're in a

hurry.

Manual:

More a status than an operating mode, Manual activates after you switch the

preamp on. 000 appears in the display telling you that the preamp is in Manual

mode.

In Manual mode, the preamp responds just like any conventional preamp that

isn't ready for MIDI.

You can't store settings in Manual mode. However, any settings that you dial in

while the preamp is in Manual mode can serve as a source, and you can copy this

configuration to a target MIDI preset.

MSF is disabled in Manual mode.

MIDI Channel Select Mode:

You can activate this routine to select MIDI channels Poly 01 to 16, OMNI or MIDI

Off for MIDI preset banks A and B.

MIDI-Volume:

This feature lets you control the preamp's Master knob via an external MIDI

volume pedal. The pedal must be connected to a suitable MIDI foot board (for

example, the ENGL Z-12-EXP) and it must be able to send MIDI data via MIDI

controller number 7. You must enable this option in MIDI Volume setup before

you can access and control the preamp's Master volume.

MIDI Volume Setup Mode:

You can activate this routine to switch the MIDI volume controller on (external

MIDI volume control is enabled) or off (external MIDI volume control is disabled).

Microcontroller:

A semiconductor chip by any other name. In this preamp, three microcontrollers

slave away for your tweaking pleasure, carrying out a mind-boggling amount of

arithmetic operations. Powered by custom-designed, extremely complicated

software, these chips control the different functions of the preamp and constantly

monitor the settings of the various components that are responsible for shaping

tube-driven signals.
