  • Our take on the 4-Channel Headphone Amplifier, Cleaner Audio, 4 TRS Outputs

    The Pyle PHA40 is a compact four-channel headphone amp that lets four people listen to one source at once, each with their own volume knob. It uses four high-power stereo amplifiers and low-noise op-amps to keep the sound clean at high levels. It suits small studios, rehearsal spaces and bands tracking together who need cheap, simple monitor distribution. Against pricier multi-channel amps it gives up balanced inputs, metering and per-channel tone control, but it does the basic job of splitting one mix to four pairs of headphones.

    What reviewers say

    Owners of the PHA40 generally describe it as a simple, reliable way to give several people their own headphone volume from one source. Most praise its clean sound and small footprint for the money; some note the basic feature set and unbalanced connections limit it to home and small-studio use.

    What people mention
    • Sound qualityPraisedOwners say it stays clean and quiet at normal levels and holds up when pushed.
    • Volume controlsPraisedFour independent knobs let each listener set their own level, which reviewers find useful for tracking.
    • Build and knobsMixedThe compact chassis is liked, but some find the knobs small and light-feeling.
    • ConnectivityCriticisedOnly one unbalanced 1/4-inch input is offered, so separate mixes and long balanced runs are not possible.

    Questions and answers

    Can each listener control their own volume?
    Yes. Each of the four outputs has its own rotary volume control, so four people can set different levels from the same source.
    What kind of headphones can I plug in?
    Any headphones with a 1/4-inch TRS plug. Headphones with a 3.5mm plug need an adapter.

    Yes. It runs on the included DC 12V/150mA power supply and has no battery option.
    Can I connect a mixer or interface?
    Yes, through the single 1/4-inch TRS input. All four listeners hear that one source, so it does not create separate mixes.
    How does it compare with a multi-channel amp with balanced inputs?
    It is simpler and smaller, but it lacks balanced connections, metering and per-channel routing that larger studio amps offer.
    What is in the box?
