Tri-amplifies your sound for serious high-fidelity tone.
The K4 amplifier is an advanced and extremely versatile stereo keyboard amp that delivers a wide spectrum of tones. More importantly, it has the ability to sound right with a minimum amount of tweaking. The Traynor K4 consists of three separate, built-in amplifiers, for true stereo operation with a mono-summed woofer. A 200-watt Low Frequency amplifier drives a 12-inch, 200-watt woofer, while a pair of 50 watt amps drive the left and right channels, delivering the mid and high frequencies through a set of 4.5-inch, 30-watt midrange drivers and a pair of 20-watt 2.5-inch compression drivers with horns.
One unique feature of the K4 amp is how Channel 1 utilizes a pair of 12AX7 tubes, one for each channel, left and right. These preamp tubes supply warmth and smooth out the harsh harmonic overtones often associated with many modern Digital keyboards. It also excels at maintaining the warmth and character of vintage synthesizers and organs where it isn't always practical to use the much larger powered speaker cabinets they are typically associated with.
There is also a select switch to toggle between using either the tube or a Solid-State signal path, bypassing the tube on the input altogether, for those times when the cleanest signal path possible is preferred. Channel one also features a foot switchable Tube Overdrive control, for those who like to add a small amount of grit to their playing. Depending on the level, a small amount of warmth right up to full grit can be had from the Tube Overdrive. Natural tube compression is a very desired tone as the subtle dynamics can't be properly emulated by most of today's digital workstations. Use this feature to add some grit to an otherwise sterile keyboard tone to make it a truly vintage, tube-based one. A single button latching footswitch, like the AFS-1 can be used to engage the Lead/Overdrive feature. If a footswitch is connected, it will disable the front panel switch. Additional tonal control can be had thanks to the three band EQ and 5 position (Bypass, Studio, Live, Piano, Organ) selectable voicing presets.
Like Channel One, Channel Two also features its' own Gain control as well as a 3 band EQ. Available inputs include a stereo pair of balanced 1/4-inch TRS inputs and a single XLR, for mono only operation.
Channel Three uses an independent Gain control to set the levels for the stereo pair of balanced 1/4-inch TRS inputs and stereo pair of RCA inputs. All three channels feature their own input clip LED's for simple monitoring of input levels from the darkest of stages and a single Master Volume and Power Switch let you be heard when you want to.
Channel 4 inputs and Gain control can be found on the rear panel. The possibilities are endless with it. Use it to bring in an external click track or drum monitor mix, or get a microphone feed from the FOH or monitor console. The two inputs can even be used for monitoring two different sources if desired. The signal goes directly into the power amplifier, so it bypasses the Master Volume and Line Outs entirely.

Channel 4 Monitor
Channel 4 has been added as an extra channel for monitoring purposes, the signal does not mix in with the Main stereo bus and thus the Line Out is not affected by it. The input has it own level control. The left and right inputs can even be used as two separate monitoring sources and the signal goes directly into the amplifiers, bypassing the master volume entirely.
Rear panel controls for Channel 4 include: Gain control
Stereo balanced 1/4-inch TRS inputs for mono or stereo operation
Subwoofer Out
Subwoofer out is provided via a TRS 1/4-inch jack. This mono signal features no filtering, so it can be used to feed a powered sub, remote powered speakers or any other device requiring a mono-summed Full range signal.
Balanced Stereo XLR Line Outs
These are used to connect directly to a mixing console, or for direct recording. The Line Out jacks are Pre-Master control, turning the Master control up or down will not have any affect on the level of the Line Out jacks.
Ground Lift
The ground lift switch is located beside the XLR jacks. It lifts the balanced Line out ground (Pin 1) when pushed in.
Footswitch Jack
When used in conjunction with any single button latching footswitch, like the AFS-1, the Tube Overdrive mode can be activated or deactivated remotely at will.
Cooling system
Two 3-inch fans cool the K4, The fans, normally operate at a low speed, the speed increases depending on how hard the amplifier is working. The air intake vent is located at the top of the cabinet and the exhaust vents are located at the front and back of amplifier.
Caution: The top vent must be kept clear in order for the air to enter into the amplifiers. The rear and front vents are used to allow the warm air out of the unit.
Head Phone Jack
A 1/4-inch headphone jack is provided on the rear panel as well. When the jack is used, it mutes the signal that comes out of the amplifier, with the exception of the monitor channel 4.
Jam with tube/solid state sounds, stereo/mono speaker array, and plenty of power for your sound. Call or click today to order.
The Traynor K4 amplifier is great for a multiple-keyboard rig run in stereo. I've owned mine for about 8 months now and I love it! Compare the features this amp has to other options on the market, and overall, I believe you'll come to the conclusion that this product is a winner. I use my K4 to amplify 4 keyboards, all run in stereo: A Korg Triton Extreme 88, a Hammond XK-3c, a Yamaha Motif XS-6, and an Alesis Micron. I use it in my 80s/90s/current rock/pop 5-piece band, with a praise band at church, and for my solo gigs with a Yamaha P-140 digital piano. Its great to have a built-in direct box with XLR outs, with a level independent from the main amp volume. Its also cool to have a seperate monitor in - this has occasionally been a lifesaver for me when soundguys show up with not enough monitors. For these occasions, I usually keep a couple XLR - trs adaptors, so the soundguy can pass me a monitor feed from the stage snake. I also find myself using the "Tube Lead Mode" when my band covers material with two guitar parts - the "grunge" added by the tubes goes a long way towards making me sound like that second guitar, especially when taken in context of the total mix. (Given a good guitar sample to start with, of course.) Traynor also adds versatility by having twin RCA connectors plus and XLR mic slot. I've even occasionally used the extra mono-summed balanced output on back to feed xtra reinforcement monitors when there's no soundguy. Overall, when you look at the features this amp has, and the versatility it will give you, you won't want to accept one of the lesser "vanilla" amps available. The 3-way speakers and tri-amped setup sound great in just about any live situation. I find I almost have a relationship with this amp like that of most guitarists and their amps...along with my keyboards, its part of my sound palette.

I've owned mine for four months. I spent a lot of time checking out amps before I bought this one. I was very pleased with this amp from day one, but it really began to come to life after about 30-40 hours of use. It is very flexible, has all the features I need and its built like a tank. Its a great Canadian product I'm proud to own. Its a little pricey, but worth every penny.

The best I have found

I use a Hammond xk-1, Roland Piano, and Fantom with this amp. The K4 has plenty of power, but also has the best sound I've heard. I have used the other popular amps, in fact I still own them , but they stay in my studio. I was a little uneasy buying this amp without ever hearing it, but it has so much flexibility and looks like it is built much sturdier than any other amp I own. I would suggest letting the amp cool down completely after a gig before moving it, to save the tubes.
I use an amp stand to get it up off the stage and that seems to work well for projecting the sound.
Other amps (Bose, Motion Sound) can suffice in certain applications, but overall I have not found a better sounding amp.
A little pricey, yes. You can get soundthing that is just OK for much less, But remember, You get what you pay for.

This little beast is very impressive!! I never really tried a keyboard amp that big in term of wattages, the closest I have been was a Roland KC350 which is about the weight as this one. If you are searching for a loud amp that can keep its quality going there, this one is something to consider. I was debating between the Motion Sound and this one and I took this one. I got no regrets whatsoever. I am still amazed about the quality and loudness this amp can give.

Killer Amp!

I use the Traynor K4 with a Roland RD700SX keyboard and the Roland VK-8M organ module. The amp produces piano and organ sounds far superior to the equivalent Roland and Hartke amps. The tones are natural and I have power to spare. I'm asking the guitarist to turn up his stack. If you are a gigging pro, it doesn't make sense to use anything else. You will pay more, but you will get an amp that's substantially lighter, with much more power, and with much better tone.
