WMS 400 WIRELESS SYSTEM
The new WMS 400 offers a unique combination of class-leading
audio quality with wide dynamic range, incredible ease of setup and
operation and low operating cost. Up to 24 WMS 400 systems can be
used simultaneously, so it is perfect for any small or medium-sized
application. Since WMS 400 uses the antenna components and other
accessories from the WMS 4000, it is possible to put together high-
performance, yet cost-effective custom multi-channel wireless systems.
SR 400 RECEIVER
• Available in two 30-MHz bands with 1,200 frequencies each that
permit use of up to 12 simultaneous systems in each band.
• Integrated frequency management system with automatic scan-
ning finds clean frequencies quickly and easily.
• Infra-red link uploads frequency and setup data to transmitter quickly.
• Rehearsal mode records all operating parameters during sound
check to help avoid performance problems.
• Two-color backlit display allows easy monitoring of all operating
parameters and turns from green to red when a fault condition
occurs including low battery, input overload, mute, low RF and
other parameters.
• 1/2-rack size all-metal chassis comes complete with all necessary
hardware for mounting either singly or side-by-side.
• Professional outputs: balanced 3-pin XLR-type and unbalanced
1/4-inch jack.
HT 400 HANDHELDTRANSMITTERS
• Available with either the smooth, powerful sound of the AKG
D 880M dynamic or the detailed clarity of the AKG C 900M con-
denser microphone.
• Infra-red data link allows setup within seconds.
• Full up to 50 mW output for freedom from dropouts due to low RF.
• Low operating cost – 6 hours of use from a standard “AA” bat-
tery or 8 hours from the optional high-current rechargeable.
• Built-in charging contacts allow batteries to be recharged without
removing them from the transmitter.
• LCD display shows frequency, group and hours of remaining battery life.
• Ergonomically-styled chassis has soft-touch finish for comfortable
handling. Color-coded inserts are available for easy identification.
PT 400 BODYPACKTRANSMITTER
• Extremely small size.
• Infra-red data link allows setup in seconds.
• Full up to 50 mW output for freedom from dropouts due to low RF.
• Low operating cost – 6 hours of use from a standard “AA” bat-
tery or 8 hours from the optional high-current rechargeable.
• Built-in charging contacts allow batteries to be recharged without
removing them from the transmitter.
• External mute switch interface allows unit to be muted remotely.
• LCD display shows frequency, group and hours of remaining bat-
tery life accurately.
• Compatible with a wide range of AKG lavalier and headset micro-
phones. Also comes with 1/4-inch cable for use with instruments.
