QR Code Link to This Post
A pair of 50 watt amplifiers powers 4.5-inch midrange and 2.5-inch high-frequency drivers mounted in stereo pairs on an angled front baffle. This variation of the 2.1 speaker configuration allows a stereo image to be amply felt onstage.
One of the most versatile amplifiers of its kind, the K4 offers four channels and a switch-selectable choice of tube or solid-state input stages. The tube circuit uses a pair of 12AX7As for adding warmth and smoothness to the often-sterile sound of modern digital keyboards. Thanks to Lead Level and OD Trim controls, you can create natural tube compression and recreate the subtle dynamics that can't be properly emulated by most of today's digital workstations. For greater effect, this preset can be footswitched in and out.
The crisp, clean solid-state input stage is ideal for those times when precise definition of acoustic samples or instruments is required.
Versatile inputs allow two stereo sources to be connected to Channel One, while an additional stereo source or a microphone can be connected to Channel Two. Channel Three can handle an additional stereo keyboard or any other source including MP3 player or laptop where additional EQ control isn't required. Channels One and Two have separate 3-band EQ's for tone shaping, while Channel One offers an additional 5-position Voicing circuit with four presets - Studio, Live, Piano & Organ - plus an Off setting.
An indepenant fourth stereo input channel with its own Gain control can be found on the rear panel of the K4. It directly feeds the power amp section, bypassing the Line Out and Master volume. This versatile feature allows an external click track, drum monitor mix or monitor feed from the PA or recording console to be played through the K4 as if it were a monitor and without being in the audience or recorded mix.
Built for the rigors of the road, the Traynor K4 is manufactured using a solid, void-free plywood cabinet construction and an all-metal grille to protect the high quality speaker components.
