Front Panel
A Master Volume control is located on the front panel along with the Power switch and LED. Front panel controls for Channel 1 include: Two parallel pairs of balanced 1/4-inch TRS inputs for mono or stereo operation
Gain, Bass, Mid, Treble controls with a boost/cut of 15db
A five position voicing selector (Bypass, Studio, Live, Piano, Organ)
Tube/Solid State input switch
Lead Level control
Overdrive Trim control
Lead Bypass switch
Input clip LED Front panel controls for Channel 2 include: Parallel pair of balanced XLR (mono only) and stereo balanced 1/4-inch TRS inputs for mono or stereo operation
Gain, Bass, Mid, Treble controls
Input clip LED
Front panel controls for Channel 3 include: Gain control
Parallel pair of unbalanced RCA and stereo balanced 1/4-inch TRS inputs for mono or stereo operation
Input clip LED
Rear panel 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 our 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. Traynor Keyboard Amps Series Overview
