Setup/Connections
Q: Is there a direct out on the Lowdown 400/750 HD series amplifiers?

Q: Can I use a Line 6 controller Lowdown 400/750 HD?
A: Yes, we recommend using the FBV Shortboard with the Lowdown series. The FBV will work with the Lowdown series (although there will be numerous buttons that have no effect), and the FBV Express will not scroll through the banks.
Q: Do the Lowdown 400/750 HD series amplifiers have an effects loop?
A: No, none of the Lowdown 400/750 HD amplifiers has an effects loop.
Q: Can I connect an external pre-amp (i.e. Line 6 POD unit) to the Lowdown 400/750 HD?
A: Yes, an external preamp can be connected to the instrument input of the Lowdown, be sure to send an instrument level signal rather than a line level signal to avoid clipping and/or damage to the Lowdown. An external pre-amp can also be run into the MP3 input jack, which would relegate the Lowdown amplifier to a powered speaker.

A: The Lowdown 400/750 HD series has two (2) parallel Neutrik Speakon outputs to connect a single 4 ohm cabinet or an 8 ohm pair of cabinets.
***Connecting a single Line 6 LowDown cabinet (8 ohms) to the LowDown 400/750 HD single 4 ohm output cuts the power output to the cabinet in half. 375 watts from the LowDown 750 HD, and 200 watts from the LowDown 400 HD.
