Mackie MP-240: Hybrid Dual-Driver Sound With Studio Detail

The Mackie MP-240 is a hybrid dual driver professional in-ear monitor that pairs a single dynamic driver with a single balanced armature in each earpiece, splitting the work through a custom crossover so bass and treble each get a purpose-built transducer. Tuned across 20 Hz to 20 kHz with a sensitive 108 dB/mW rating, it draws on the live-sound engineering Mackie has refined in Woodinville, Washington since 1988. The first time the low end lands with the highs still crystal clear, you understand what a hybrid design is for.

Two Driver Types, Each Doing What It Does Best

A dynamic driver moves the most air and delivers deep, physical bass, while a balanced armature is tiny, fast, and exceptionally detailed through the mids and highs. The MP-240 combines both and uses a custom passive crossover to route low frequencies to the dynamic driver and the upper range to the armature. Because neither driver is asked to cover the whole spectrum, you hear tight, clear bass under impeccably articulate vocals and cymbals, the sonic signature that separates hybrid IEMs from single-driver designs.

Sensitive, Easy to Drive, Built to Isolate

With 16 ohms of impedance and 108 dB per milliwatt of sensitivity, the MP-240 plays loud and clean from modest sources like wireless bodypacks and phone-powered interfaces, and its 10 mW maximum input power keeps it comfortably within the reach of typical monitor rigs. The ergonomically molded, low-profile enclosure seals up to 40 dB of ambient noise passively, so stage volume and crowd wash never bury the detail the balanced armature works to reveal.

Detachable MMCX Cable and a Custom Fit

A detachable cable roughly 59 inches (1500 mm) long connects through swiveling MMCX sockets, so you can replace a worn lead or swap in the optional MP-BTA Bluetooth adapter without retiring the earpieces. The over-ear routing keeps the cable behind your head and out of the way, and three types of ear tips in three sizes each let you tune the seal for comfort, isolation, and the fullest bass response your ears allow.

Where the MP-240 Shines

Vocalists and acoustic players favor the balanced armature's clarity for pitch and diction, while drummers and bassists get the dynamic driver's low-end weight for timing and feel. In the studio the hybrid balance makes a dependable mixing and tracking reference, and for detailed listening on the move it renders texture that single-driver earphones smear together. It is one monitor that crosses from the stage to the mix position to the commute.

Everything Packed and Protected

Each MP-240 ships with its detachable MMCX cable, three styles of ear tips in three sizes, a gold-plated 1/8-inch to 1/4-inch adapter for amps and mixers, and a hard carry case that guards the drivers and organizes the accessories between sessions. Add the MP-BTA adapter down the line and the same monitors go wireless, a hybrid design that keeps earning its place in your kit.
