2 input mixer with filters, mute, thru, phase reverse,

2-input mixer with LPF & HPF filters, mute-output, THRU, phase-reverse and volume controls
Custom 2-input Mixer with Filters / THRU outputs / Phase Reverse / MUTE
This is a custom 2-input mixer features two variable filters: a Low Pass filter (LPF, 220Hz-16.5kHz) and a High Pass Filter (HPF, 20Hz-300Hz) both with a 12dB/octave steepness. The filters are placed in series (LPF → HPF), both affecting the mixed signal.
Each input (A, B) has its own dedicated volume knob and its own THRU-output which gives you the ability to route the original signal to a different chain of effects or another device. Additionally, a phase reverse switch is available for channel-A in order to help you overcome any phasing problems when mixing signals that are 180º out of phase.

A foot-switch gives you the ability to silently mute/unmute the output in real time. The foot-switch affects only the mixer output and not the THRU outputs.

The mixer can handle instrument level signals and higher line level signals as well. If you need more headroom you can use a power supply larger than 9V (max. 24V).
The very high impedance of the inputs and the very low impedance of the outputs ensures the best possible inter-connectivity with your gear and that your signal will maintain its clarity and tone.
