Can both inputs on the Hartke LH1000 be used simultaneously?

Can both inputs on the Hartke LH1000 be used simultaneously?

I play bass and synthesizer and I'd like to be able to use both at the same time (I have MIDI bass pedals to trigger sounds/samples while I play bass, a la Geddy Lee). I just want to be sure that plugging something into the 2nd input won't disable the 1st.

I'm looking to ditch my puny 75-watt keyboard amp in favor of this bad boy. I realize I'll lose some top end and I'll need to keep the gain turned down low (unless I'm playing a gritty Hammond B3 patch, that is ).

Thanks in advance!

pretty sure the answer is no.

You mean the active and passive inputs on the front? A lot of amps you can run both, not sure if the lh is that way or not. May actually sound pretty good depending on the cab. Watch the levels on the keys and the clip light if there is one.

Thanks, guys...both reasonable responses. I guess, I have a 50/50 chance of being wrong...lol

I'm hoping that someone who has an LH1000 knows. Otherwise, I'll probably wind up contacting Hartke customer service.

You can use both inputs. At rehearsals I use it with a drum machine. I have no problems at all.

I don't own the LH series but I do own a HA3500, you can use both inputs on it at the same time. You also may want to try plugging the midi into the effects return on the back of the amp.

I wouldn't suggest it. I have a guitar player who does this; a guitar and loops. He's blown his share of speakers doing this.

You can probably do it but the results will probably be less than satisfactory. Some issues you will face is the output from your synth is line level and the input of the amp is instrument level. You can probably use the active input to better match the levels. You will also be sharing the EQ section in the preamp which may colour your synth in undesirable ways. A better way to approach this may be to use the effects loop on your amp in conjunction with a small mixer so you can mix in your synth signal without going through your amp EQ. As someone has mentioned, your cab will also shape the tone of your synth. If you have a pretty hifi cab with a flat response like an Acme or Fearful then you're all set.

You could run the bass into your normal input, through the EQ, then out of the effects send. Then, add your synth to your bass with a Y-Box back into the effects return.

Thanks for all your replies, everyone. I'm not so sure I want to go with the LH1000, now. No aux in...but 1000 watts sure sounds sweet! ;-)

Thanks, in particular, to bassomane for clarifyng the dual input functionality. :-)

Just plug the keys into the effects return and adjust your volume from the keyboard since there is no mix knob on the LH1000. Effects loops are typically low impedance in order to accommodate rack gear, so it handles keys without adding noise. The LH1000 effects loop is 100 ohms so you should be good.

I do it all the time at rehearsals with my Roland D-Bass combo (keys go through the PA live though). You don't get the full spectrum of sound through the bass amp but it definitely does the trick for volume.

If he blew guitar speakers doing it, it was likely from low frequency stuff from the drum loops at volume, no problem for a bass cab.

+1 to using a small mixer in front of the amp. There are several inexpensive mixers that'll fit on a pedalboard. I'm doing exactly the same thing with bass and synth, and the mixer is the best solution.
