RCF S.p.A. thanks you for purchasing this product, which has been designed to guarantee reliability and high
performance.
INTRODUCTION ABOUT THE BUSINESS MUSIC LINE
BUSINESS MUSIC line includes DMA 82 / DMA 162 digital matrix amplifiers, DMA 162P (also called DMA[P] in the following) digital
power amplifier, BM 404 paging microphone, remote controls and speakers, offering a complete sound system and maximizing the
overall acoustic performance. DMA / DMA[P] amplifiers are extremely compact (1/2 19” rack unit wide and 1 unit high) that make
them ideal for either desktop or rack installation (with optional accessories) and are suitable for a wide range of system solutions,
from retail stores to bars and restaurants, meeting rooms, education or public facilities and any A/V application. Their accurate design
together with environmental robustness (IP 30 protection grade and high efficiency thermal dissipation) represents a junction point
between professional and consumer markets.
This line includes both ceiling and wall mount speakers, which have professional acoustic performances and a high valued industrial
design, it has different configuration levels, from the user friendly front control panel to the RCF ‘RDNet’ for large and complex systems,
with a highly scalable architecture. Control units can send up to four mono / two stereo audio channels to satellite units through a
single CAT5 cable. This allows to increase the installed power and create a multi-room architecture as well, with a simple connection
among devices.
DMA 82 / DMA 162 DESCRIPTION AND MAIN FEATURES
DMA 82 and DMA 162 are two-channel class-D matrix amplifiers, both equipped with a powerful DSP platform, allowing managing
inputs and outputs in terms of routing and equalization (a complete set of processing functions is available, including PEQ, FIR filters,
bass enhancement, limiters, compressors and environmental equalization); moreover, dedicated presets for RCF speakers have been
implemented to optimize their acoustic performance. The two models only differ in the output power:
- DMA 82 either 2 ch. x 80 W RMS @ 4 Ω or a single 160 W 70 V line
- DMA 162 either 2 ch. x 160 W RMS @ 4 Ω or a single 320 W 70 V line.
Each DMA is suitable for either desktop or rack installation (thanks to its dedicated optional accessory). Each unit has 2 stereo LINE
audio inputs on RCA connectors, 1 MIC+LINE balanced audio input on removable screw terminals and a LINE audio output with a
switchable low-pass filter useful for the connection to an active subwoofer. A dedicated input having RJ 45 connector allows the
connection of up to four BM 404 paging microphones (interlocked one another on a single chain). A RC 401 wall-mount remote
control can be linked to each output channel in order to adjust its respective volume level and select the desired audio input. DMA
can send up to 4 audio channels to satellite DMA[P] units (through a BUS with a single CAT5 cable), combining a flexible and scalable
multi-room architecture with an easy connection and installation. Its configuration is user friendly and can be carried out through
either its front panel controls (with OLED display) or RDNet (when its optional board is installed).
DMA 162P DESCRIPTION AND MAIN FEATURES
DMA 162P is a two-channel class-D power amplifier. Output power: either 2 channels x 160 W RMS @ 4 Ω - or a single 320 W 70 V
line. Up to 4 DMA [P] can be linked to a single DMA unit in order to increase the system output power and implement multi-room
architectures. However, each DMA[P] can be used as a stand alone amplifier as well. Each amplifier is suitable for either desktop or
rack installation (thanks to its dedicated optional accessory). DMA[P] can receive processed audio signals from a DMA amplifier on a
four-channel audio BUS (either four mono or one stereo and two mono or two stereo, the four signals are the same sent to the DMA
power amplifiers), or as alternative, it is possible to select the local stereo LINE input (by closing the dedicated contact). A LINE output
is also available, with a switchable low-pass filter for the connection to an active subwoofer. Its configuration can be carried out
though either the dip-switches on its rear panel or RDNet (when its optional board is installed).
