The A4s is a Complete Redesign of 64 Audio’s 4-Driver Platform That is Elevated by a Dynamic Low Frequency Driver, Making it 64 Audio’s Second Ever Hybrid Custom IEM
VANCOUVER, Wash., Nov. 15, 2021 – 64 Audio, the leader in custom and universal fit in-ear monitors, is proud to announce the launch of the A4s 4-driver custom in-ear monitor. Now available with an MSRP of $1,099 and with a special introductory offer of $989 for a limited time, 64 Audio’s second hybrid custom IEM is the ideal choice for musicians looking for a rich enveloping monitoring experience.
“The A4s is a complete redesign of our four driver platform that is elevated by a dynamic low frequency driver, making it 64 Audio’s second ever hybrid custom IEM,” explained Vitaliy Belonozhko, 64 Audio founder and chief sound designer. “Along with this major update, inside A4s is our tia™ technology, LID™ and our patented apex and 3Dfit technologies. The frequency response, detail, and soundstage capabilities of A4s exceed other audiophile products at almost any price point.”
The A4s is a true audiophile-grade IEM in every aspect as the frequency response follows proven targets for fidelity and preference. The dynamic driver produced bass is powerful, enveloping, and deep while avoiding being muddy. The mids are revealing and present, contributing greatly to its wide stereo imaging and separation. Its high frequency response toes the line between neutral and detailed…balanced enough to mix a record with while offering the extension needed to make a recording really come alive.
Additional A4s specifications and features include:
- Frequency Response: 10Hz – 20kHz
- Crossover: Integrated 4-way passive crossover
- Transducer Configuration: 1 dynamic low, 1 BA low-mid, 1 BA high-mid, 1 tia high
- Sensitivity: 107dB/mW @ 1kHz @ 1mW (94mV)
- Impedance: 11Ω @ 1kHz
- Isolation: 20dB w/ m20 module, -15dB w/ m15 module. Ships with M20 Module standard
tia is a technology exclusive to 64 Audio that works by eliminating sound-altering tubes and dampers. Sound produced by the tia system is able to disperse freely and effortlessly, yielding an incredibly smooth and musical frequency response.
LID is a correctional circuit that presents a flat impedance to the amplifier, resulting in a sound devoid of artificial coloration. Exclusive to 64 Audio, LID ensures a consistent frequency response regardless of the source, making it perfect for musicians plugging into a variety of equipment.
3DFit is a new way of manufacturing custom in-ear monitors that preserves the details of your ear impressions for the most comfortable-fitting IEMs possible.
64 Audio’s patented Air Pressure Exchange (apex) is a pneumatically interactive vent that releases air pressure in a sealed ear canal. This venting alleviates listener fatigue and opens the soundstage. Unlike competitor venting solutions, apex preserves the bass frequencies and produces a more open soundstage, which helps the listener distinguish individual instruments. The apex module is also engineered with features to prevent vent-clogging and wind noise. Its compact and durable construction is virtually maintenance-free, designed for the most demanding users.
From studio to stage to sophisticated home audio environments, 64 Audio has created the industry’s most innovative universal and custom-built in-ear monitors available to date. The company was founded in 2010 by Vitaliy Belonozhko, a sound engineer who has been working with musicians and production companies for nearly two decades. He discovered the advantages of IEMs over traditional floor “wedges” and recognized that a better solution to in-ear monitoring was needed. Today, 64 Audio supplies products worldwide to some of the best-known musicians, singers, and engineers in the world, as well as discerning audiophiles who demand nothing but the best sound reproduction from their systems. With new and unrivaled technologies such as apex®, LID™, tia™ and 3D-Fit™, 64 Audio excels in challenging traditional earphone designs to bring-to-market unique and innovative audio products.
