100-watt Keyboard Amp/Monitor with Built-in 4-channel Mixer

If you're a working keyboard player you know this story: the guitar player's amp is on 11, the bass player is vibrating the stage, and the drummer needs to lay off the caffeine, while you're begging the sound man to give you more keys in your monitor. Well, there's still hope! The Harke KM100 gives keyboard players some much-needed attention. The Hartke KM100 is the ideal solution for the player who needs a flexible mix/monitor system to handle a sophisticated instrument rig, and who demands a high quality amplifier that faithfully reproduces the sound, nuances, and soul of their performance.


Hartke KM100 Keyboard Amplifier at a Glance:
  • 2-way, 100-watt keyboard amp with 12" driver and 1" tweeter.
  • Built in 4-channel mixer.
  • Hartke kickback-style cabinet.


2-way, 100-watt keyboard Amp
The KM100 has 100 watts of power driving a 12" aluminum cone driver and a 1" titanium compression driver, enclosed in an innovative kickback design, giving you a powerful full-range 2-way professional monitoring system.

Built-in Mixer
For players with multiple keyboards and sound modules an additional mixer isn't needed because the KM100 has one built-in. The mixer has a Mic/Line input on channel 1, as well as three additional line inputs, and a stereo Aux in. The amplifier also features a 7-band graphic equalizer, and an XLR direct output.

Convenient Kickback Cabinet
Hartke's famous kickback design lets you tilt the KM100 back so that the speaker points up to your ear, so you can use the KM100 as a stage monitor or point it upwards toward the audience for better projection. The KM100 is easy to transport, plus, the KM100's solid construction makes it a reliable performer from night-to-night and venue-to-venue.

So far so good

by Kevin B. Selby from Tri-Cities, WA

Music Background: Semi-Pro musician
I have used my KM100 twice now.

First in my carpeted studio with another musician (guitar/vocals) we had plenty of power and nice decent sound. Be careful of jacking the highs too mu... read more [+]ch because this thing can CRANK the high EQ frequencies and it hurts!!

Second experience: today I was outdoors in a medium space with a guitarist and a sax player.

I had my Yamaha PSR-S700 keyboard (drums, bass, keyboard sounds) connected via stereo 1/4" to stereo RCA plugged into the Auxiliary jack of the KM100 and the aux volume on the KM100 at noon.

The sax player had a little Yamaha mixer and he plugged his sax condenser mic and my Shure beta 58 into the little Yammy mixer and then we routed that via a single 1/4" to Input 4 on the KM100 and put Input 4's volume at about 10:00.

The guitarist had his own Line 6 amp and was self-contained.

The overall volume knob on the KM100 was at noon.

The KM100 was on the ground tilted back on its wedge shape so that it projected up a little. We had it between and behind myself and the sax player.

EQ-wise: I pulled the mids down a tad and boosted bass and highs very slightly.

Overall impression:
This thing has PLENTY of power. The 12" cone looks pretty rugged and indestructable. We were at maybe half power and quite easily filled the grassy lawn area where we were. Even with that many "instruments" (drums, bass, keyboard sounds, sax, and vocals) pouring into the KM100 it reproduced everything cleanly. In retrospect I could have boosted the bass a little more.

I fully expected to wrestle with feedback from the two microphones, but partly because we carefully pointed them off axis and partly because they're good mic's we had NO feedback problems.

I am very impressed with this little guy so far. It sounded so good that for medium to larger outdoor gigs I think I may go get another KM100 and do everything stereo and have twice the power and have two point sources of sound. For most indoor gigs (smaller to medium rooms), ONE of these is plenty. VERY solid sound. I had considered the Behringer 15" keyboard amp because it has effects on board, but I'm totally okay with the Hartke KM100 not having effects because I'll just use an outboard mixer or recording unit (like the Zoom R16) to run vocals through and get a little splash of reverb. For instrumental jazz you're basically done. Plug a keyboard (like the Yamaha arranger series that have drums bass and keyboard sounds) into the KM100 and maybe a sax mic and you're good to go!

VERY happy with this purchase. Maybe down the road I'll use my Zoom H2 to record a duo/trio where I'm using it for the "PA" so you can at least hear a rough approximation of what it can do. Well done Hartke/Samson!! close [-]

Great sound - quite heavy!

No question the sound quality of this baby is awesome. Received many compliments from different audiences. Kick back design doesn't add much. Resting on a chair sounds better. But it weights 75 pounds... read more [+] so be careful when you lug this thing. Check out the Roland KC150. Save your back! close [-]

Sweetwater Advice

Carson McClain
Just reading the specs makes me want one. Hartke amps sound great, they are versatile and they are loud. If you're a keyboard player consider Hartke for your next purchase. They balance quality with useful features.

Our Customers Say...

I can talk to my Sales Engineer about any piece of equipment, and he always steers me in the right direction. He truly knows what he's talking about, and he never tries to over-sell me on anything. If he worked in the Nashville area, I'd probably owe him about 20 dinners by now!
