Vanguard Audio Labs V34C Gen2 “LOLLI” Interchangeable Large-Diaphragm Capsule Head

The Vanguard Audio Labs V34C Gen2 “LOLLI” is a patent-pending interchangeable large-diaphragm capsule head that converts any small-diaphragm pencil condenser with M21x0.5 threading into a multi-pattern large-diaphragm recording tool — switchable between cardioid and omnidirectional via a top-mounted switch. At its core is the same proprietary 34mm edge-terminated, gold-sputtered 3µm Mylar dual-capsule assembly used in the Vanguard V44S and V13 microphones, custom-voiced through a hand-tuning process for warm, full lows, a precise midrange, and smooth high-frequency response. The capsule assembly is seated in a precision shockmount saddle inside a CNC-machined aircraft-grade aluminum chassis with open-weave mesh, carefully radiused interior geometry, and precision-machined venting to prevent standing reflections and support an open-air acoustic voicing. Designed in the USA and assembled in Portland, Oregon, every V34C Gen2 undergoes 100% audio and visual quality control before shipping, and is backed by a five-year warranty.

Key Features

• Converts pencil condensers to large-diaphragm multi-pattern operation — fits any microphone with M21x0.5 threading, including small-diaphragm instrument condensers from a wide range of manufacturers; transforms an instrument microphone into a large-diaphragm, switchable-pattern studio tool in seconds
• 34mm edge-terminated dual-capsule assembly — shared with V44S and V13 — the same proprietary capsule used in Vanguard Audio Labs’ V44S and V13 microphones; 3µm gold-sputtered Mylar diaphragms; edge-terminated design provides high sensitivity and transient detail; custom-voiced by hand for warm lows, precise midrange, and smooth high-frequency response
• Switchable cardioid and omnidirectional polar patterns — top-mounted switch allows instant pattern selection between cardioid and omnidirectional; adds multi-pattern versatility to microphones that would otherwise be fixed-pattern
• CNC-machined aircraft-grade aluminum chassis — precision-machined from solid aluminum billets; open-weave mesh and carefully radiused interior prevent standing reflections; precision-machined venting supports open-air acoustic voicing; retro-aesthetic design references classic broadcast microphone styling
• Custom suspension saddle — internally shockmounted capsule assembly — capsule seated in a custom shockmount saddle within the chassis for mechanical isolation; reduces vibration transmission from the microphone body to the capsule assembly
• Designed in the USA — assembled in Portland, Oregon — designed by a team with over 65 years of combined experience; vetted by professional engineers and producers; every unit undergoes 100% audio and visual quality control before hand-packing
• Five-year warranty — Vanguard Audio Labs backs every V34C Gen2 with a five-year warranty
