The Alpha Omega Ultra is the most versatile bass preamplifier we?ve designed: With its two distinct distortion circuits (Alpha and Omega), extremely high dynamic range, six-band active graphic EQ, dedicated headphone output and balanced direct output with switchable digital impulse-response cabinet emulation make for an incredibly complete tool for the modern bass player.
Features:
Input & Outputs
Input: Connect your instrument or output from your pedal board to the ¼? mono jack.
Aux In: This 3.5mm stereo input allows you to practice with backing tracks from e.g. your smartphone or laptop. Auxiliary input can only be used with the headphone output.
The pedal does not control the level, it must be set from your audio source. Remember to always first set the level low before connecting anything to the aux in!.
Headphone Output: Alpha·Omega Ultra has an internal stereo headphone amplifier capable of driving a minimum load of 16 ohms from the 3.5mm stereo jack. Use the Master volume control to adjust the level.
9V DC: Only use a regulated 9V DC adapter with a center-negative plug
Current draw : 130mA
Output: Connect from the ¼? Output jack to the input of your amplifier or another effects pedal.
Direct Output: Balanced XLR output for connecting the pedal to a microphone preamp, PA system etc.
Ground lift: Disconnects the signal ground on the Direct Output to break any ground loops. Set this switch to either position that has less noise. The switch does not affect the ¼? output.
Cab Sim: Toggle the cabinet simulation on/off on the Direct Output. This switch completely bypasses all digital circuits and allows you to get a zero latency signal when needed.
USB: A Micro USB B connector allows you to connect the pedal to PC/Mac to load cabinet simulation impulse responses to the pedal and control various other settings.
