The mobile speaker and amplifier system DSC-150 from RCS Audio-Systems is a compact sound system solution for events with up to 250 people. The device is designed for playback of music and speech and is intended for use in applications such as conferences, seminars, advertising events, trade fairs, schools, hotels, and sports events. The base unit is delivered without a UHF receiver and can optionally be expanded with various modules to adapt functionality to specific requirements.

Applications

The DSC-150 is designed for mobile applications where clear and powerful sound reproduction is required. It is particularly suitable for events indoors and outdoors where portable, robust, and high-performance sound technology is needed. The system is designed for small to medium-sized events with fewer than 250 participants. Its use in schools, presentations, hotels, or sports events is especially appropriate due to its mobile design and long battery life.

Functions and Equipment in Detail

The device features a 150 W RMS power amplifier implemented in Class-D technology. This technology enables high efficiency and relatively low power consumption, resulting in extended battery life. The system is equipped with a robust, impact- and scratch-resistant plastic housing that meets the requirements of mobile use. Pre-installed castors and an extendable handle facilitate transportation. Integrated sound control and a battery status indicator support operation. The system can be equipped with up to two UHF receiver modules (U1/U2), with True-Diversity technology ensuring a stable wireless connection. The VOICE-OVER function allows speech to be overlaid on music, which is useful for presentations or events.

Technology Explained Simply

The Class-D amplifier ensures efficient power usage, extending battery life compared to conventional amplifiers. True-Diversity technology in the UHF receivers reduces interference susceptibility and ensures reliable signal transmission, especially with moving microphones. The frequency bands range from 863–865 MHz, with 16 selectable frequencies. The system can be operated via mains power (230 V) or battery, with battery runtime optimized by the low power consumption of Class-D technology. Integrated pitch control in optional media modules allows adjustment of playback speed.

Compatibility and Accessories

The DSC-150 can be expanded with various modules. These include the UHF receiver module DSC-016 B, the BT module DSM-100 BT for audio transmission from smartphones, tablets, or PCs, and the CD/MP3/USB/SD-Card player DSM-003 CD. Modules can be retrofitted, and when ordered with a media module, the system is fully equipped and ready for operation. Available accessories include handheld microphones (UH-016 B), bodypack transmitters (UB-016), lavalier microphones (LA-200 B), and headset microphones (HS-200 S/B). The system includes storage space for two handheld microphones and connection cables.

Installation and Mounting

The DSC-150 is delivered as a complete unit and requires no additional mounting. Modules are inserted directly into the device, and when ordered with a media module, the system is fully assembled and ready for use. Installation is done by simply inserting the modules into the designated slots. Power supply is via mains connection (230 V) or integrated batteries, which can be charged in the charging compartment for four batteries (1.2 V). Operation is controlled via the integrated master board with sound control and power switch.

Advantages in Operation

The combination of high power output, low power consumption, and robust design makes the DSC-150 a reliable solution for mobile sound systems. The long battery life allows operation without constant access to mains power. The integrated VOICE-OVER function and the ability to use various media modules increase flexibility. Pre-installed castors and an extendable handle facilitate transportation, making the system quickly and easily deployable at different locations. True-Diversity technology ensures a stable wireless connection, which is especially important with moving microphones.
