WMS
470
AKG WMS 470 is your best choice for any application calling for a solution that is more flexible than
a simple plug-and-play system, yet easy to set up and operate. WMS 470 is a high-performance
solution for any situations where several radio mics will be used simultaneously, including gigs at
clubs and stages, for regional events, seminars or house of worship applications.
With 30 MHz tuning range you can select 1200 frequencies and operate with up to 20 channels
simultaneously within the same frequency band or up to 48 channels in multiple bands.
WMS 470 is the most cost-efficient wireless systems. Transmitters are powered by a single AA size
Alkaline (LR6), Lithium (FR6) or Ni-MH rechargeable (HR6) battery and provide up to 14 hours of
continuous operation.
Being compatible and based on the technology of the professional WMS 4500 wireless system you
can set up even complex wireless systems using antenna splitters, power supply units and the
whole range of professional directional or omni-directional antennas.

AKG’s CU 400 is a fast charger that rapidly charges the rechargeable battery inside
the transmitter without damaging the cell element. CU 400 charger determines the
optimum charge current. Charging is terminated when both batteries are fully
charged.
The CU 400 charger use the pulse technology in which a pulse is fed to the battery.
This DC pulse has a strictly controlled rise time, pulse width, pulse repetition rate
(frequency) and amplitude.

The charger shall be housed in a rugged plastic case with two multifunctional charging slots for charging WMS 470 Series wireless transmitters. Each charging slot shall
accommodate a handheld or bodypack transmitter and the charger shall be capable of charging any combination of transmitters (e.g., one HT 470 and one PT 470
simultaneously). The batteries shall remain inside the transmitter(s) during charging. The charger shall detect any dry (non-rechargeable) battery inside a transmitter and
automatically stop the charging cycle if a dry battery is inserted. A status LED shall be placed in front of each charging slot. These tricolor (red/amber/green) LEDs shall
indicate the charger's current operating status: amber - battery is being tested; red - battery is being charged; green - battery is fully charged and charging cycle finished;
flashing red - error. The voltage and temperature shall be monitored during the charging cycle and a signal given at the end of a charging cycle to indicate that full
capacity has been reached. All required safety parameters shall be monitored and the charging cycle stopped if one or more safety parameters fall below or exceed the
acceptable range. Operating voltage shall be 5 VDC, 1.5 A max. The charger shall accept NiMH or NiCd rechargeable batteries with a minimum capacity of 1500 mAh.
Typical charging current shall be 1.4 A when one charging slot is used and 0.7 A when both slots are used simultaneously, typical charging time 1.5 hours when one
charging slot is used and 3 hours when both slots are used simultaneously (depending on battery type and capacity). The charger shall measure 188 x 115 x 78 mm
(LxHxD), weigh approx. 420 g, and be enameled black. The charger shall be the CU 400 or equivalent.

Antenna System
PS 4000 W Power splitter – Antenna distributor to feed
up to 5 receiver with the RF-signal of a pair of antennas.
To feed more than 5 receivers the PS 4000 W provide a
link output to cascade up to 3 PS 4000 W.
SRA 2 B/W Directional antenna – Active antenna with
integrated high performance booster required for use
with long cable runs.
SRA 2 W Directional antenna – Passive antenna for
use with short cable runs (<10 m)
RA 4000 B/W Omni-directional antenna – Active
antenna with integrated high performance booster
required for use with long cable runs.
RA 4000 W Omni-directional antenna – Passive
antenna for use with short cable runs (<10 m)
ASU 4000 Antenna Supply Unit – Remote power supply
for small systems where no PS 4000 W is in use to
provide the necessary power for the active antennas.
ZAPD-21 Passive splitter – 2-into-1 antenna combiner
for indoor and outdoor use. Can be used either to split
signals or combine them as needed.
AB 4000 Antenna Booster – High performance antenna
booster for inserting into long antenna cables. One AB
4000 can compensate for approx. 17 dB of cable
attenuation. Up to three boosters can be used in series
for extremely long cable runs.
Wireless Microphone System
PSU 4000 Power supply unit – Three high current 12V
DC outputs feed the power to 3 PS 4000 W antenna
distributors. Via PS 4000 W 12 receiver and up to 8
active antenna components (SRA 2 B/W, RA 4000 B/W,
AB 4000) get the power through the antenna cable.
