Tiptop Audio: Buchla Model 207t Mixer/Preamp
3,8 / 5,0 | 
The Buchla modules keep coming; this time, it’s the classic Model 207t Mixer/Preamplifier that can mix modular and bring in line and guitar signals.
Model 207t
The Buchla 207t is straightforward and good-looking. It has six inputs along the bottom, a stereo output and two mono monitor outputs. It has another stereo input called Expansion In which, very handily, you can plug the output of another 207t to give yourself a 12-channel mixer.
The Preamp section offers a 1/4″ microphone input with a gain knob. You can switch between 55dB and 70dB amplifier range that should cover most microphones and enable you to bring it up to Eurorack levels. You could also plug in an electric guitar or line-level source or match it up with the 296t filter bank for some vocoder action. To tun it through the mixer, you just have to patch the preamp output to any of the six inputs.
Routing and control
Above the inputs are two rows of switches. The yellow ones send the channel to the monitor outputs; the blue ones send it to the main signal output. The sliders are attenuators for the signal output; it has no effect on the monitor outputs.
Along the top is a row of four knobs which control the panning of channels B through the E. Channels A and F are special. Channel A is panned all the way to the left and has a CV input that can move it further right, depending on the amount of voltage you pump in there. Channel F does the exact opposite. It’s a nifty way to add some movement.
The Model 207t is open for preorders at $245.
Art Coming soon
In other Tiptop Audio news, the innovative ART polyphonic modular system should start to ship after NAMM. Maybe soon we’ll be able to work out what it’s all about.
