dj gear. ~ AKG CU4000 AKG CU4000 Description: The CU 4000 revolutionizes battery management for wireless systems. ~ The heart of the supply system is the BP 4000 rechargeable battery pack with built-in active monitoring circuitry. ~ An integrated microprocessor continuously monitors battery status and accurately calculates the remaining battery life. ~ This puts an end to the nightmare of batteries failing in the middle of a performance. ~ A processor controlled pulse charging system charges the battery pack quickly yet gently, and the integrated "Charge Balance Management" feature makes sure that only as much energy is fed to the battery pack as had previously been drawn from it. ~ In addition, several monitoring circuits and a temperature sensor prevent the battery pack from being overcharged. ~ A self-discharge counter does not only measure battery discharge during operation but also determines the charge level after prolonged storage periods. ~ As charging begins, the BP 4000 circuitry sends all relevant data to the CU 4000 charger to "tailor" the charging process exactly to the needs of the battery pack. ~ To eliminate memory effect, the CU 4000 automatically checks whether the battery pack needs a recovery cycle and automatically starts the cycle after the user has con- firmed the start command. ~ The charger provides two dedicated compartments for charging two HT 4000 or PT 4000 transmitters or two battery packs at the same time. ~ The BP 4000 plus CU 4000 system is an investment that will quickly help reduce battery cost and reduce environmental hazards from used batteries. ~ Charging current: 1.5 A Operating voltage: 12 VDC, 1.3 A Charging time: 1 hour typical Recovery cycle: approx. ~ 8 hours Dimensions: 92 x 173 x 85 mm (3.6 x 6.8 x 3.3 in.) Weight: approx. ~ 580 g (1.2 lbs.) AKG CU4000 Features: Intelligent battery supply system comprising CU 4000 charging unit and BP 4000 battery pack Microprocessor controlled charge/discharge monitoring function One-hour quick charging and Battery Recovery Management Charging compartment allows battery pack to be charged inside the transmitter AKG CU4000 Specifications: The intelligent charging system shall comprise a charger and two dedicated battery packs. ~ The charger shall feature a rugged plastic case with two multifunctional charging receptacles for charging the WMS 4000 transmitters or the dedicated battery pack. ~ Each charging receptacle shall accept either a handheld transmitter, a bodypack transmitter, or the dedicated battery pack and it shall be possible to charge any combination of these devices (e.g., an HT 4000 and a battery pack). ~ The battery pack may remain inside the transmitter during charging. ~ The charger shall use high-tech, microprocessor-controlled charging circuitry with trickle charging, automatic shutoff at the turning point, and 2-stage overcharging protection. ~ The charger shall automatically check whether the transmitter is on, switch the transmitter off, and charge the battery pack. ~ A bic lighting; dj gear; drum sticks; orchesta percussion; electric drums; acoustic drums; percussion; drums; midi; sound modules; groove stations; arrangers; portable keyboards; digital pianos; workstations; synths; electric bass; bass; amps; acoustic guitar; electric guitar; musical instruments;
