PreSonus HP4 4-Channel Headphone Amplifier and ATH-M50X Bundle

In this review the PreSonus HP4 and Audio-Technica ATH-M50X bundle is evaluated as a compact personal monitoring solution for project studios and mobile rigs. The main reason to consider this bundle is its combination of a reliable four-output headphone amplifier that can double as a control room monitor device and the ATH-M50X headphones known for clear, accurate bass and wide frequency response. Together they deliver a practical, studio-oriented monitoring setup for engineers, producers and musicians who need clean headphone mixes for tracking or mixing.

Key Features

• Four independent outputs: The HP4 offers four stereo headphone outputs so multiple performers can monitor simultaneously with individual level control for each feed.
• 130 mW per channel: Each HP4 output supplies enough power for a wide range of headphones, providing solid headroom and a low noise floor for critical listening.
• Daisy-chainable monitor control: The HP4 can be daisy-chained to expand monitoring and also serves as a simple control room monitor control for small studio setups.
• Accurate sound signature: The ATH-M50X headphones deliver exceptional clarity and accurate bass response across an extended frequency range, useful for critical tracking and reference listening.
• Durable, professional build: ATH-M50X features a circumaural design with 90 degree swiveling earcups and professional-grade durability for studio and on-location use.
• Personal monitoring focus: The bundle pairs powerful amplification with a highly regarded closed-back headphone to create an unmatched personal monitoring experience for many audio professionals.

Who It's For

This bundle is aimed at small studios, home recordists, mobile recording engineers and bands who need to send mixes to several performers at once without sacrificing clarity. The HP4 is especially suited to sessions where independent level control and low noise are important, while the ATH-M50X give a dependable, revealing sound for tracking and initial mix decisions.

Those who need advanced routing, integrated DSP mixing or more than four discrete headphone mixes should look elsewhere; this kit is not a replacement for a large-format monitor controller or a multi-output in-ear monitoring system with individual mixes and talkback functionality.

Pros & Cons

Cons

• Not a substitute for multi-channel monitor mixers if you require individual mixes or integrated talkback for each performer.

Yes, the HP4 provides per-channel level control so each performer can set their headphone volume independently.

Are the ATH-M50X suitable for critical mixing?
The ATH-M50X are praised for clarity and accurate bass response and are excellent for tracking and reference listening, though some mix engineers prefer open-back models for final mastering choices.

Can the HP4 be expanded for more outputs?
The HP4 can be daisy-chained to add monitoring stations, but expands relatively simply and is not a full substitute for dedicated large-format monitor mixers.
