Sennheiser MKH 8040 Stereoset (Matched Cardioid Pair)

Product Overview

The Sennheiser MKH 8040 Stereoset is a factory-matched pair of MKH 8040 cardioid RF condenser capsules, each supplied with an MZX 8000 XLR module. Sennheiser matches both capsules for consistent sensitivity and frequency response, ensuring that stereo image accuracy is maintained throughout the recording chain. The cardioid polar pattern makes this pair the primary choice for XY, ORTF, and other coincident or near-coincident stereo techniques. RF condenser technology adds moisture resistance that keeps both capsules reliably matched in outdoor and live environments.

Product Description

The MKH 8040 Stereoset delivers two factory-matched cardioid RF condenser capsules along with two MZX 8000 XLR modules, providing a complete, ready-to-deploy stereo microphone system from Sennheiser's professional MKH 8000 series. Factory matching means Sennheiser has measured both capsules and verified that their sensitivity and frequency response fall within tightly defined tolerances — an essential requirement for stereo techniques such as XY, ORTF, and near-coincident cardioid arrays, where amplitude differences between the two channels directly translate into stereo image errors. The cardioid polar pattern rejects rear-hemisphere sound, making the MKH 8040 pair effective in acoustically challenging recording environments where ambient noise or room reflections need to be controlled. Like all MKH 8000 capsules, the MKH 8040 uses RF condenser technology rather than conventional DC bias, providing robust immunity to humidity and temperature extremes that would degrade performance or mismatch conventional condenser pairs over time or across environments. Self-noise of 13 dB(A) per capsule is among the lowest available for a cardioid microphone, making this pair equally at home on quiet classical ensemble recordings and full dynamic-range orchestral sessions. The capsules and modules are compatible with all other components in the MKH 8000 system, allowing engineers to expand or reconfigure their microphone kit without redundancy. The MKH 8040 Stereoset is in regular use on professional film location sets, classical recording sessions, and broadcast productions worldwide.

Frequently Asked Questions

Why choose the MKH 8040 Stereoset over two individual MKH 8040 sets?

The Stereoset guarantees factory-matched tolerances between both capsules. Units purchased individually are not certified as a matched pair. For critical stereo work where imaging accuracy matters, the Stereoset is the correct choice.

What stereo techniques work best with the MKH 8040 cardioid pattern?

The cardioid pattern is well suited to XY (coincident), ORTF, and near-coincident stereo configurations. It is also used as the outer capsules in Decca tree and five-channel surround setups.

Can I mix MKH 8040 and MKH 8020 capsules in the same recording setup?

Yes. The MKH 8000 system is fully modular, and engineers routinely combine cardioid (8040) and omnidirectional (8020) capsules in the same session — for example, spot mics (8040) alongside a Decca tree (8020).

How close can the two capsules be positioned for XY stereo?

The miniature form factor of the MKH 8040 capsule allows the two capsules to be placed extremely close together for coincident XY configurations, minimising time-of-arrival differences and phantom centre smearing.

Is the MKH 8040 Stereoset suitable for film production?

Yes. The MKH 8040 is a widely used film production microphone. The stereoset is particularly valuable for stereo location ambience, stereo effects, and production sound where matched capsules are required.
