citronic 170.862UK Compact Mixer with DSP, USB Play/Record/PC and Bluetooth

Compact format audio mixer with 2, 4 or 6 mono input channels, a stereo line input and a further mini jack stereo input. Each mono mic/line channel has a combo XLR/jack input with +48V phantom power switchable in pairs for the XLR inputs. Each mic/line channel has a Gain control for matching the input source and a low-cut switch to filter out rumble or handling noise from microphones. Each mono channel also has High/Low EQ controls and an FX level control. Pairs of mono channels can be linked to act as a stereo left + right pair as required. The onboard foot-switchable DSP effects engine has 99 presets for delay, reverb and modulation effects, each of which can be adjusted using two parameter controls. An onboard Bluetooth receiver has an illuminated pairing button and independent volume control. The USB type-A port on the top panel is for playback of audio files or can be used to record the main outputs to a USB storage device or as an external audio device when connected to a laptop. Output is delivered to a pair of balanced XLR connectors to provide low noise operation for high quality studio or live performances.

TS808 Tube Screamer Guitar Pedal Kit

This kit is based on the most iconic overdrive pedal ever, the Tube Screamer TS-808. Our version comes with a true-bypass 3PDT footswitch & daughterboard so your signal passes straight through the pedal when it is not engaged in order to preserve your tone. Using high-quality components, this pedal is less noisy and more reliable than the original (when assembled correctly).

As with the original, the three knobs allow you to control the Overdrive amount, output Level and the Tone. The Tone knob changes the peak frequency from ~220Hz (at 0%) to 1.1kHZ (at 100%) with approx. 6db/octave roll-off. In order to save battery life, the input jack is wired so the pedal turns off if the jack is unplugged while the pedal is powered by battery only. 

This PCB will fit nicely in a 1590B (G150) enclosure without the battery, or in a 1550D (G111) with a battery.

Please note: this kit comes with a Texas Instruments NE5532AP opamp; let us know if you want us to send a RC4558 opamp instead.
