LAGUNA 4 is a four channel mic preamp featuring dual-output technology. With both Transformer and Transformer-less outputs active on every channel, LAGUNA offers unique creative possibilities in tone and signal routing. Whether you need the purity of a DC-Coupled output, or want to take advantage of the qualities a massive Transformer brings to the table, LAGUNA has you covered. When unsure of which type to use, simply print both outputs and blend later at mix-down. Freedom and flexibility in a 1U chassis.
Standard features include switchable Hi/Lo Input Impedance, High Pass Filters and Phantom Power. When Phantom is switched off the input becomes dc-coupled and optimized for Ribbon mics. Indeed, with these features LAGUNA is ideal for any microphone. Precision Rotary Gain controls match every channel within ±0.1dB. With its wide gain range and impressive headroom there is no need for pads.
Of course, LAGUNA upholds Pueblo Audio's esteemed reputation for fidelity, resolution and 3D sound stage. But how to characterize its distinctive sonics? Well, maybe you're someone who likes classic/vintage preamps but sometimes wishes for less noise, more focus and tracks that easily stack in a mix. Or maybe you're a person who goes for clean, life-like sound but could use just one extra "click" of harmonic energy and punch. If so then we believe you'll find LAGUNA hits that sweet spot.

FAQ's (frequently asked questions)
Q: You already make so many preamps. Why add LAGUNA?
Over the years we have received suggestions and requests about our original JR-Series preamps. We finally condensed this wish list into LAGUNA, a universal studio workhorse which retains Pueblo's high product standards. We also recognized that customers sometimes find themselves unsure and maybe even anxious about which type of preamps to buy. Which design is best for the mics they use? Do they need transformers or not? Will the features cover enough bases or will they somehow get stuck down the line? With LAGUNA's flexible and straight forward capabilities we aimed to lay those concerns to rest.
Q: What's the difference between your LAGUNA and JR2/2 preamps?
It’s a little tricky to contrast the two preamps because both share some traits but differ in others. Pueblo Audio's strategy is to design gear that offers solutions to problems that are not yet solved (or at least not solved as well as they could be). Our style is to solve these problems at fundamental operational levels. The JR-Series solved the desire to better capture the tone, atmosphere and performer's personality under remote recording situations. Not with questionable voicing or saturation but by supporting both mic and preamp operations to reach their best resolution potentials. Even in the face of location recording challenges like high EMI, poor power service, long cable runs, etc..
To better tailor LAGUNA for the studio environment we took advantage of transformers for their properties of natural balance, galvanic isolation and (with our high performance units) tasteful harmonic relief. Please note that the transformers are not just "tacked on" the end. Rather they are integrated into the design itself, becoming an essential circuit element. Again, solving issues at fundamental levels.
Q: Why no Polarity Invert (aka "Phase Reverse") option?
Polarity Invert buttons are installed nearly everywhere these days. You find them in most DI's, Consoles, Computer Interfaces and DAW Software. Maybe it's good marketing but with so many opportunities to "flip the phase" along the signal path, why add yet another? It seems a bit superfluous and increases the chance of accidentally double-flipping, sabotaging the desired polarity. We felt it better to just omit this option and gain a little more signal path integrity. Besides, it helps with the price, too.
