6-Channel Mixer

The Doheny Audio 6-Channel Mixer is a versatile and compact addition to any studio or live setup. Hand-soldered with a combination of metal film and carbon film resistors, it offers a subtle tonal variety—precision where it counts, warmth where it matters.

The circuit is based around the reliable TL072 op-amp, with a few thoughtful modifications for added stability. During development, we included an inverted output as a design experiment—but in most setups, it has little to no audible effect. You’ll only need to use the main output.

This unit is mono, but if you’re looking for stereo functionality, using two units makes for a killer stereo mixer to add to your arsenal.

Where the DA Mixer really shines is when paired with a transformer, delivering enhanced depth, warmth, and rich overtones that elevate your entire signal chain.

Features:
• 6 mono input channels
• Individual volume control
• Clean analog summing circuit
• Standard 9V DC power
• LED power indicator
• Boutique-grade components
• Built for utility and tone

Great for summing synths, drum machines, pedals, or external FX loops—this compact unit adds clarity and character to your signal chain without getting in the way.
