5 Operating Notes

CU

700

 

 

•Rechargeable batteries (those included or those you may buy later) are delivered un- charged or partially charged. Therefore, you will need to charge each new battery before using it.

•The battery capacity indication will work best if you charge the batteries fully using the CU 700 charger.

•If you replace the rechargeable batteries inside a transmitter be sure to fully charge the batteries in order to calibrate the charging control system.

•Battery life depends on battery quality. Do not use any rechargeable batteries other than the same type as those included with the charger.

Each charging slot features a tricolor STATUS LED that indicates the current operating status of the re- spective charging slot (">…<" marks an LED flashing in the respective color):

Table 1: STATUS LED indications

1.Check that rechargeable batteries are inside the transmitter battery compartment.

If there is no battery inside the battery compart- ment, do not place the transmitter in a charging slot before you inserted rechargeable batteries into the transmitter.

2.Insert the transmitter into the charging slot so that the display on the transmitter faces the LEDs on the charger. The charger will automatically power the transmitter via the charging contacts.

3.Never switch the transmitter ON during the charging cycle. This may cause the charger to falsely indicate a completed charging cycle be- fore charging is actually completed.

•To avoid damaging the charger, do not try to charge dry batteries.

CU700 specifications

The AKG Acoustics CU700 is a high-performance condenser microphone designed for professional audio applications. With its sleek, modern design and advanced acoustic technologies, the CU700 offers exceptional sound quality and versatility that meets the demands of both studio and live sound environments.

At the heart of the CU700 is its exceptional transducer technology. The microphone features a large-diaphragm design that captures a wide frequency range from 20 Hz to 20 kHz. This wide frequency response ensures that the microphone delivers rich, detailed sound across vocals and instruments, making it an ideal choice for recording vocals, acoustic guitars, strings, and percussion. The CU700's sensitivity and low self-noise levels allow for the capture of nuanced performances in both quiet and loud settings.

One of the standout features of the CU700 is its switchable polar patterns. Users can choose between cardioid, omnidirectional, and figure-eight patterns, providing the flexibility needed for various recording situations. The cardioid pattern is particularly effective for rejecting ambient noise, making it a great choice for isolating vocals or instruments in controlled environments. In contrast, the omnidirectional pattern is perfect for capturing sound from all directions, while the figure-eight is ideal for duet vocals or stereo recording setups.

The CU700 is also equipped with an integrated high-pass filter and a pad switch, enabling users to tailor the microphone's response to suit specific recording needs. The high-pass filter minimizes low-frequency rumble, helpful for reducing unwanted sounds in live settings. The pad switch allows the microphone to handle high sound pressure levels, making it suitable for loud sources such as guitar amplifiers or brass instruments.

In terms of build quality, the CU700 is robust yet lightweight, constructed with durable materials designed to withstand professional use. It features a standard XLR connector, ensuring compatibility with a variety of audio interfaces and mixing consoles.

The AKG Acoustics CU700 is a versatile microphone that excels in various applications. With its exceptional sound quality, advanced features, and robust design, it stands out as a reliable choice for musicians, sound engineers, and content creators seeking to elevate their audio production. Whether in the studio or on stage, the CU700 delivers the professional sound quality required for modern audio applications.
