5.The charger may be opened, serviced, and repaired by authorized personnel only. The charger con- tains no user-serviceable parts.

6.Place the charger at least 1 inch away from walls or other equipment to ensure adequate heat dissi- pation from the charger. If the charger overheats, the charging cycle will be stopped immediately.

7.Before connecting the charger to power, check that the AC mains voltage stated on the included power supply is identical to the AC mains voltage available where you will use the charger.

8.Do not operate the charger with any power supply other than the included AC adapter with an output voltage of 5 VDC. Using a power supply with an AC output and/or a different output voltage may cause serious damage to the charger.

9.If you will not use the charger for a long period of time, disconnect the charger from power. To pre- vent unwanted discharging, be sure to remove the transmitter(s) from the charger every time you dis- connect the charger from power.

10.Do not place the charger near heat sources such as radiators, heating ducts, or amplifiers, etc. and do not expose it to direct sunlight, excessive dust, moisture, rain, mechanical vibrations, or shock.

12.Use the charger for the applications described in this manual only. AKG cannot accept any liability for damages resulting from improper handling or misuse.

1.2Environment 1. The charger will draw a low current even when the charging mode is off. To save energy, disconnect the charger from power if you will not use the charger for a long period of time. To prevent unwanted discharging, be sure to remove the transmitter(s) from the charger every time you disconnect the charger from power.

2.Be sure to dispose of used batteries as required by local waste disposal rules. Never throw batteries into a fire (risk of explosion) or garbage can.

3.When scrapping the charger, separate the case, circuit boards, and cables, and dispose of all com- ponents in accordance with local waste disposal rules.

The CU 400 has been designed specifically for use with the WMS 400 system.

The charger provides two charging slots specially shaped to accept the HT 400/PT 400 transmitters. The charging slots operate completely independently so you can charge two rechargeable batteries simulta- neously. You do not need to remove the battery from the transmitter for charging.

Designed specifically for use with the WMS 400 transmitters, the CU 400 charger

•monitors battery voltages and temperatures during charging;

•generates a flag signaling the end of the charging cycle upon reaching maximum capacity;

•monitors all required safety parameters and will stop the charging cycle if one or more safety para- meters are out of range.

The charger checks the battery inside the transmitter and will automatically deactivate the charging func- tion if it detects a dry battery.

There is one STATUS LED in front of each charging slot.

These tricolor (red/orange/green) LEDs indicate the current operating status of the charger.

DC input The DC 5V jack on the rear panel accepts the DC cable on the included AC adapter.

CU 400 specifications

AKG Acoustics CU 400 is a premium studio microphone designed for professional recording and broadcasting applications. Known for its exceptional performance and versatility, the CU 400 embodies the high standards expected from AKG, a brand renowned in the audio industry for over seven decades. This microphone is particularly favored by sound engineers and musicians alike due to its pristine sound quality and robust construction.

One of the standout features of the CU 400 is its large diaphragm design, which enables it to capture an extended frequency range. This characteristic is vital for accurately reproducing vocals and a wide array of instruments, making it an excellent choice for studio recordings. The frequency response of the CU 400 spans from 20 Hz to 20 kHz, ensuring detailed clarity in both low-end and high-frequency ranges. This makes it ideal for a variety of applications, encompassing vocals, acoustic instruments, and even orchestral recordings.

The CU 400 incorporates advanced condenser technology, which enhances its sensitivity and transient response. This allows the microphone to pick up the finest details of the sound source, resulting in recordings that are not only clear but also dynamic and expressive. Additionally, the microphone features a cardioid polar pattern, which helps in minimizing background noise and focusing on the sound source directly in front of it. This characteristic is particularly useful in live recording situations and environments where ambient noise could interfere with the quality of the audio.

Another notable aspect of the AKG CU 400 is its durable build quality. Designed for both studio and stage applications, it withstands the rigors of professional use. The microphone's metal housing provides protection from physical damage, while the included shock mount helps to reduce vibrations and handling noise that could detract from the recording quality.

The CU 400 is also equipped with an integrated low-cut filter and a -20 dB pad, offering further flexibility in various recording situations. The low-cut filter reduces low-frequency rumble, while the pad allows the microphone to handle high sound pressure levels without distortion.

In summary, the AKG Acoustics CU 400 is a versatile, high-performance microphone that excels in a wide range of recording scenarios. Its combination of large diaphragm technology, cardioid pickup pattern, and robust construction makes it an invaluable tool for both amateur and professional audio engineers. Whether used for music production, voiceovers, or live performances, the CU 400 delivers the sound quality and reliability that AKG is known for.
