The Tiptop 207t is a modern reimagining of the classic Don Buchla 207 Mixer/Preamplifier from the 1970s 200 Series. The 207t model mixer/preamplifier from Tiptop includes a built-in preamp, providing the ability to amplify external instruments and microphones. Its six-channel mixer offers multiple signal routing choices, such as the capability to route channels to the monitor and L&R signal outputs, with individual loudness and panning control for each channel. This makes the 207t a versatile addition to any modular setup.
Each channel has a Mon switch that sends the channel’s signal to the monitor outputs, which are always full-volume and summed to mono, making it useful for basic monitoring applications or rudimentary mixing. The Prog switch sends the signal to the L&R signal outputs, with loudness controlled by the Level Adjustment slider and panning determined by the Channel Assignment knobs. The first and sixth channels offer voltage control of panning; these channels are hard-panned when no CV is applied. Get full control and precision with Tiptop Buchla Model 207t Mixer/Preamplifier. The Mon and Prog switches allow you to tailor your signal for different monitoring or mixing needs, and the voltage control of panning on the first and sixth channels offers even more versatility. Elevate your mixing experience and take your sound to the next level!
The preamp section features a 1/4″ input and multiple gain settings, making it suitable for use with external line level instruments, electric guitars, or dynamic microphones. The continuous amplification control provides added flexibility for your audio needs. Finally, the Expansion In is a stereo input that sums to the left and right main outputs, which is great for chaining multiple 207t modules or adding another stereo source at the final output.
While the 207t’s functionality may be simple, it is an essential part of any 200t system, serving as the glue that holds everything together. The Tiptop 207t is a fantastic mixer/preamp option that delivers quality sound and reliable performance.
