Multi-Pattern FET Condenser Microphone
Thank you for choosing the NEW VANGUARD V4 gen2 Microphone!
From day one at Vanguard Audio Labs, we have always sought ways to improve our products
and we always will…that is part of our mission. As a result, on the NEW gen2 mics we have
upgraded nearly all of the key signal-path components to audiophile-grade parts, sourced from
American parts manufacturers. These upgrades have netted us a lower signal-to-noise ratio
(even though we already had a superb reputation for low noise mics), and vastly improved
sound staging. In addition, we also made physical design improvements in several areas, as well
as giving the finish a beautiful upgrade. In short, we feel the new V4 gen2 microphone is a true
world-class mic.
Enjoy!
Your VANGUARD V4 microphone is carefully packed at our workshop. The padded pinewood
mic box and aluminum carrying case are designed to protect the microphone during shipping
and storage. In addition, before any microphone is released, the final assembly and testing is
performed here in sunny Southern California to make sure the mic is ready for you to reliably
enjoy in professional recording situations.
TO AVOID DAMAGE TO YOUR MICROPHONE, PLEASE READ THIS ENTIRE MANUAL
BEFORE PLUGGING IN THE V4 FOR THE FIRST TIME!
OVERVIEW
The Vanguard V4 is a large-diaphragm multi-pattern FET condenser microphone lovingly crafted
by experts over the course of 2 years. It is designed to be a versatile & reliable professional tool in
the vein of highly-sought-after vintage “workhorse” microphones of yesteryear. With a
custom-voiced 3-micron capsule with 3 selectable polar patterns, pad switch, premium

transformerless cryogenically-treated FET circuitry, and our heavy-duty VLSM shockmount, the V4
will be one of your favorite utility microphones.
PERFORMANCE
The VANGUARD V4 was conceived and commissioned to establish a new performance standard
at a very affordable price point. While being visually stunning, the V4’s audio performance will
inspire confidence from any artist, engineer or producer, with a sonic signature that is rich, yet
natural, with no high-frequency hype or distortion. We designed the V4 with the character of
yesteryear’s iconic vintage microphones in mind, while also utilizing the latest technology to
ensure that every nuance and detail of the performance is faithfully recorded. The
custom-voiced Vanguard capsule is switchable between cardioid, omnidirectional, and figure-8
pickup patterns and the pad switch allows the V4 to accurately capture virtually any source
material.
DESIGN
The VANGUARD V4 is very different from other mics in its price range. It is designed and
precision-built in limited quantities to “no-compromise” standards.
The V4 is a response to demand for a “mono” version of our V44S stereo microphone. While it
utilizes largely the same circuitry, we also included a pad switch on the rear of the V4
microphone to make it even more useful.
We started with a 34mm edge-terminated, gold-sputtered Mylar 3µm dual-capsule assembly
and custom-voiced it with a proprietary hand-tuning process, placing the capsule in an
open-weave headbasket for a natural sound with low internal reflections.
We then created a transformerless solid-state circuit that matches the unique musical properties
of our capsules and loaded it with premium-grade, over-spec components sourced from
manufacturers around the world. We cryogenically treated critical components in the signal &
power paths, including an ultra-high-grade FET.
Aesthetically, the precision-machined stainless steel body is coated with our signature Pinot Noir
finish with a deep, lustrous gloss. We accented the color with polished nickel trim and a
precision-cast Vanguard badge. Your V4’s serial number is laser-engraved on the lower rear of
the microphone.
The V4 was designed by a team of experts with more than 65 years of experience and vetted by
world-famous engineers and producers.

QUALITY
The V4 was designed in the USA, and undergoes final assembly in sunny Southern California. We
perform 100% quality control - every single microphone undergoes a series of stringent audio
and visual tests here in Southern California before being hand-packed.
Every part of the V4 was designed to be robust and reliable. Wherever possible, over-specced
components were utilized. The deep-cycle cryogenic treatment improves the lifespan,
efficiency, and performance of critical electronic components. Stainless steel, brass, aluminum,
and zinc are part of the heavy-duty construction. Every Vanguard microphone is confidently
backed by our FIVE-YEAR WARRANTY.
ACCESSORIES
When you buy a V4, you also get a VLSM Heavy-Duty Shockmount. We wanted to rethink the
standard “spider-style” shockmount of old, and designed the VLSM with a few nifty features. First
is the open front, which allows you to position the microphone as close to the source as
necessary. Second, we install aerospace-grade suspension rings that won’t break, sag, crack, or
stretch over time.
When not in use, your V4 should be stored in its padded pinewood box. We also include a
microfiber sleeve so you can Practice Safe Storage™ even when the mic stays on the stand in
between sessions.
The black aluminum carrying case with the V4 keeps your microphone and shockmount in one
place.
USAGE
The VANGUARD V4 excels in a multitude of recording situations. It is a superior choice for vocals,
acoustic guitar, strings, brass, drum overheads, room mic’ing, and the delicate nuances of
piano, choral, and orchestral recording - essentially any acoustic instrument. Tested in a diversity
of situations, acoustic environments, styles, and genres, we found that the V4 was most often the
top option, despite being matched against microphones several times its cost.
POLAR PATTERNS
The V4 capsule is independently switchable between three polar patterns - cardioid,
omnidirectional, and figure-8/bidirectional.

HOW TO SET UP YOUR V4 MICROPHONE FOR USE
1) Set up your audio cables.
-The V4 takes a standard 3-pin XLR cable. Plug the male end into the XLR jack on your
preamp, and run the female end to the mic stand for your V4 microphone. Make sure to
leave enough slack and route the cable safely so it won’t be a tripping hazard. You may
need to reposition your mic stand so you have enough cable length.
-The V4 requires phantom power to operate. Do not apply phantom power until all cables
are routed and plugged in at both sides
2) Set up the V4 microphone.
-It’s always best to set up your V4 microphone last, and take it down first, whenever setting
up or putting away your gear. During other stages of setup, the microphone might
accidentally be bumped or knocked over.
-Remove the VLSM Shockmount from the aluminum carrying case. Thread it onto the
microphone stand until tight, and then position the shockmount.
-Remove the V4 microphone from its wood storage box and storage bag. Hold the
microphone carefully and thread the base of the V4 microphone into the threaded locking
nut of the VLSM shockmount until tight. Don’t over-tighten - you might need to re-adjust the
microphone’s angle.
-Plug the female end of the XLR cable into the bottom of the V4 microphone, taking care to
align the cable correctly before plugging it in. You can look at the bottom of the
microphone and see the slotted insert on the side of the XLR jack, and correctly align the
slotted insert of the XLR cable with it. Phantom power should always be off when plugging
and unplugging the V4 microphone. Incorrect alignment of the cable when phantom
power is on may result in electric shock or damage to your V4 microphone.
-Position your V4 microphone as desired towards your sound source. If you are using the V4
microphone on vocals, it is important to use a high quality Pop Filter to protect the capsule
against breath moisture, as well as plosive blasts like “P”, “K”, “T”, etc. Failure to use a pop
filter may result in damage to your microphone.
3) Turn on the phantom power on your mixer, preamp, interface, or other device.
-NOTE: You won’t hear any sound for several seconds as the microphone voltages stabilize.

CARE AND PRECAUTIONS
• When not in use, please store your V4 microphone in the provided padded wooden
microphone case. We recommend keeping the plastic sleeve that the microphone is shipped
in along with the silica gel desiccant packet and keeping it on the microphone when not in
use to prevent debris or moisture build-up on the capsule. The provided microfiber storage bag
can also be used for this.
• When using for close-mic’d vocals, it is important to use a high-quality Pop Filter to protect the
capsule against breath moisture, as well as plosive blasts like “P”, “K”, “T”, etc. Failure to use a
Pop Filter may result in damage to your microphone.
• Always protect your V4 from any hard jolts, drops, and vibrations. Although it is ruggedly
constructed, it is a professional tool and should be treated with respect. Always handle with
care.
