Emotiva Cmx: Audio Surge Protector?

The Emotiva CMX-2 and CMX-6 are AC line filters and not surge protectors. However, Emotiva has recently released new models of the CMX-2 and CMX-6, called the CMX-2+ and CMX-6+, which do offer surge protection in addition to the DC offset elimination and AC line filtering capabilities of the original models.

The CMX-6 is a heavy-duty power strip that provides clean power

The Emotiva CMX-6 is a heavy-duty power strip that provides clean power, free of common mode and high-frequency line noise, to six commercial-grade outlets. It is designed to be used with high-performance audio components, ensuring they receive clean power and can perform at their best.

The CMX-6 has a sleek machined aluminium case and uses both common-mode and differential-mode L/C filtering to eliminate high-frequency line noise. It also features 115 joules of surge suppression to protect audio equipment from potentially damaging line surges and transients. This protection is provided by a 115-joule metal oxide varistor with a peak surge current rating of 4500 amps.

The CMX-6's exclusive Power Direct Connect mounting system connects its three pairs of outlets directly to the high-current circuit board, ensuring the shortest possible path and eliminating power-robbing resistive losses. This system also prevents high-frequency line noise from reaching audio gear.

The CMX-6 has a magnetic circuit breaker that allows for a short-term inrush current of up to 250% of its rated load of 15 amps. It comes with a detachable IEC high-current power cord that is 7 feet long and 14 AWG x 3. The unit can be mounted vertically or horizontally and has a weight of 3.3 lbs (unboxed) and 4.5 lbs (boxed).

While the CMX-6 is not a surge protector in the traditional sense, it does offer some surge suppression to protect valuable audio equipment. It is designed to deliver clean power and ensure optimal performance from connected components.

The CMX-2 and CMX-6 are AC line filters

The CMX-2 has two commercial-grade AC outlets and is designed to eliminate DC offset, which can cause problems such as increased transformer temperature and mechanical hum. It also features a Power Direct Connect™ mounting system, which connects the outlets directly to the circuit board, minimising power loss. The CMX-2 also has a magnetic circuit breaker and high-quality common-mode and differential-mode L-C noise filtering.

The CMX-6 has six commercial-grade AC outlets and 115 joules of surge suppression to protect audio gear from line surges and transients. It also features a Power Direct Connect™ mounting system and high-quality common-mode and differential-mode L-C noise filtering.

Both the CMX-2 and CMX-6 are constructed from premium components and machined aluminium and can be mounted vertically or horizontally. They are ideal accessories for high-performance electronics, ensuring the lowest possible noise floor and protecting audio components from line noise.

The CMX-2 eliminates DC-offset, which can cause transformer issues

The Emotiva CMX-2 is a heavy-duty AC power strip that provides clean power, free of common mode and high-frequency line noise to two commercial-grade outlets. It features a fast-acting resettable magnetic circuit breaker and 115 joules of surge suppression to protect your valuable audio gear from potentially damaging line surges and transients.

DC offset is usually the result of unbalanced loads or flaws in the power distribution system. This can cause DC current flow in the transformers that power your audio equipment, making them run hotter and produce an audible, mechanical hum. In some extreme cases, DC offset can even damage your equipment. The CMX-2 features a DC Offset Elimination circuit that completely blocks DC offset from reaching the gear that is connected to it.

The CMX-2 is ideal for those who have issues with DC offset or suspect they have DC offset issues. It is a simple and effective solution to this problem, and at $99, it is one of the most affordable options on the market.

The CMX-2 and CMX-6 continuously monitor AC power line integrity

The CMX2+ and CMX6+ are heavy-duty AC power strips that provide clean power, free of common mode and high-frequency line noise, to commercial-grade outlets. This allows the audio components connected to them to deliver their best performance under all operating conditions.

The CMX2+ and CMX6+ also include a fast-acting resettable magnetic circuit breaker and 115 joules of surge suppression to protect your valuable audio gear from potentially damaging line surges and transients. Constructed from premium components, they utilize the exclusive Power Direct Connect™ mounting system, which connects its three pairs of commercial-grade outlets directly to the high-current circuit board by the shortest possible path, eliminating power-robbing resistive losses and other problems caused by less reliable and robust wiring techniques.

Inside the sleek machined aluminium case of the CMX2+ and CMX6+, both common-mode and differential-mode L/C filtering is employed to reduce or eliminate all types of high-frequency line noise. Surge suppression is provided by a 115-joule metal oxide varistor with a peak surge current rating of 4500 Amps.

The CMX-2 and CMX-6 feature Power Direct Connect, which minimises power loss

The CMX-2 and CMX-6 are heavy-duty AC power strips that provide clean power, free of common mode and high-frequency line noise, to commercial-grade outlets. This allows the audio components connected to the CMX to deliver their best performance under all operating conditions. The CMX range also includes a fast-acting resettable magnetic circuit breaker and 115 joules of surge suppression to protect your valuable audio gear from potentially damaging line surges and transients.

The CMX-2 and CMX-6 also feature high-quality common mode and differential mode L-C noise filtering, which reduces or eliminates all types of high-frequency line noise. Surge suppression is provided by a 115-joule metal oxide varistor with a peak surge current rating of 4500 Amps. The CMX-2 and CMX-6 are constructed from premium components and feature machined aluminium cases. They can be mounted vertically or horizontally.
