Frequently Asked Questions - SGT-DI AMPEG
What power supply does the Ampeg SGT-DI require?
The SGT-DI can be powered by a standard 9V DC adapter (center negative, 2.1mm barrel) drawing about 30 mA, or by a 9V battery (not included).
How do I connect the SGT-DI to a mixing console or audio interface?
Connect the XLR output to your mixer or interface's XLR input. If needed, engage the Ground Lift switch to eliminate hum. Use a balanced cable for best performance.
Can I use the SGT-DI as a standalone preamp for recording?
Yes. The unbalanced 1/4" output can be used to connect to an amplifier or audio interface, while the XLR provides a balanced DI signal with optional speaker simulation.
What is the SGT (Super Grit Technology) control?
The SGT Drive control adds distortion and grit to your bass tone, emulating an overdriven Ampeg amplifier. Adjust the Gain and Master controls to balance the effect.
How do I activate the speaker simulation?
The built-in speaker cabinet emulation is activated via a toggle switch on the unit (consult the manual for exact location). It is typically labeled Cab Sim and affects only the XLR output.
What instruments can be used with the SGT-DI?
The SGT-DI is primarily designed for bass guitar, but it can also be used with electric guitar, keyboard, or other line-level instruments. The input impedance is high to preserve passive pickup tone.
How do I use the EQ controls on the SGT-DI?
The 3-band EQ offers Bass, Mid (semi-parametric), and Treble controls. Additionally, Ultra Low and Ultra High switches boost or cut frequencies at the extremes for deeper or brighter tones.
Can I run the SGT-DI into an amplifier's input?
Yes. Use the 1/4" Preamp Out jack to connect to your amp's input. This bypasses the DI's speaker simulation, sending a pre-EQ/pre-drive signal.
What is the phase switch used for?
The Phase switch inverts the polarity of the signal. This can help eliminate phase cancellation when using multiple microphones or DI signals simultaneously.
How do I maintain the SGT-DI?
Keep the unit dry and clean. Use a soft, dry cloth to wipe the surface. Do not use harsh chemicals. Ensure the power adapter is unplugged during cleaning. For repairs, contact an authorized Ampeg service center.
