Output terminals are provided for 4 zones which share the output of the 240W amplifier, governed by 4 individual rotary volume switches on the front panel. RJ45 inputs on the rear panel allow connection for up to two CS4 call stations to enable paging to individual or all zones. The RM244V offers versatile 4-zone control without the expense of a quad amplifier and can even be operated as the front end to an expanded public address system.Built-in USB/SD player with Bluetooth and FM tunerCompatible with CS4 call station (953.146UK)4 individual volume attenuatorsSwitchable +20V phantom powerSend/return loop for connection to audio processors or amplifiersSupplied with 19" rack-mount ears (2U)Bluetooth with programmable IDPower supply 110/230Vac, 50/60Hz (IEC)Output power : rms 240W (shared across 4 zones @ 100V)Inputs 3 x mic/line (jack/XLR), 1 x aux (RCA)Input sensitivity : mic -47dBVInput impedance : mic 5k OhmsInput sensitivity : line -10dBVInput impedance : line 1k OhmsCall station input 2 x RJ45 (for optional CS-4 call stations)Line output RCASends : returns Pre out, amp in (RCA)Channel controls Ch1, Ch2, Ch3, Media and Aux volumeOutput controls Master volume, 4 x zone volumes & mutesEqualiser : bass 100Hz ±10dBEqualiser : treble 10kHz ±10dBPhantom power +20V (switchable inputs 1-3)Audio source USB/SD player, FM tuner and Bluetooth receiverBluetooth version 5.0Fire alarm contacts 24V screw terminalsTHD +N <2% @ 1kHz (rated power)Protection Short circuit, overload, overheatSpeaker : outputs 4 x 100V (modular terminal block)Dimensions 430 x 315 x 89mm[

  • Adastra COM230 Paging Station with 2 x 30W Amplifier Adastra

    Adastra COM230 Paging Station with 2 x 30W Amplifier

    Desktop paging station with gooseneck microphone mounted via XLR into a base unit with a built-in dual amplifier. Each amplifier output has screw terminal speaker connections and can power a single 8 Ohm speaker or two 8 Ohm speakers wired in parallel (4 Ohm minimum load each output) and can be operated as a stereo Left + Right amplifier or as 2 separate zones. An AUX input on 3.5mm jack can accept a stereo line input for background music with its own volume control and is present on both channels permanently. A separate volume control governs the microphone level and there is a pre-set override that temporarily mutes the AUX input when announcements are being made. The paging process involves selecting one or both output channels via the buttons on the top panel and then pressing the "Page" button, which gives the option of paging just a single area or all areas where the speakers are installed. A simple and easy-to-use solution for where space is limited or an uncomplicated paging system is required.Independent volume controls for AUX and MICIndependent paging to each speaker outputIn-line low voltage DC power adaptor suppliedPower supply 16Vdc, 4A power adaptor (included)Output power @ 4 Ohms 2 x 30WOutput power @ 8 Ohms 2 x 15WAuxiliary input Stereo 3.5mm jackSpeaker outputs Screw terminals (removeable Euroblock)Dimensions 450 x 140 x 100mm (assembled)Weight 552gMicrophone : connector XLR

  • Adastra RS480 Slave Amplifier 100V Adastra

    Adastra RS480 Slave Amplifier 100V

    High power class-D 100V line slave amplifiers in a rack-mountable housing. Slave inputs accept standard line level audio from a mixer or RM series mixer amplifier. Slave outputs can be cascaded onto further RS slaves to build larger systems. All line level inputs are connectable via RCA sockets or hard-wired via removable screw terminals. A further removable screw terminal is provided for 100V input, which enables the RS series slave amplifier to extend an existing 100V installation by connecting directly to the 100V speaker feed, or indeed from a long distance 100V feed using standard double-insulated cable. A 24V terminal is provided for connection to a security or alert panel to mute the output if required during alarm triggering. Speaker outputs are either 100V or low impedance (switchable on RS121 and RS241) which is stable down to 2 Ohms, enabling multiple low impedance speakers to be connected if preferred. Designed to power medium to large installations from a mixer output or to expand existing systems.19" Rack-mountable 1U (120W, 240W) or 2U (360W, 480W)Efficient and lightweight Class-D amplifiersLine in and out on RCA or Euroblock terminals24V mute contacts for alarm panel muting100V signal input for extending existing speaker runsPower supply 175-264Vac 50Hz (IEC)Input signal Slave line in (RCA/screw terminal), 100V in (screw terminal)Output : signal Slave line out (RCA/screw terminal)Outputs : speaker 100V or 2 Ohms min.
