JBL CSMA 280 Commercial Mixer/Amplifier – 8-Input, 2-Output 80W per Channel Audio Solution for Retail, Restaurants & Offices (EU Version)

Description Designed for commercial and industrial use, the CSMA 280 Commercial Series Mixer/Amplifier from JBL is a mixer/amplifier with eight mixer-channel inputs and two output channels. It’s capable of reaching 80W of peak power with 10W per channel. The unit’s front panel sports volume controls for each channel, as well as two master volume adjustment knobs, two sets of bass and treble controls, and a power switch. The volume controls are illuminated so they can be seen and operated in darkened environments.The amplifier, capable of driving both eight and four Ohm loads, can be used with 70V and 100V distributed audio systems without the need for a separate transformer. On its back panel you’ll find euroblock connections for mic/line inputs, as well as unbalanced RCA inputs, speaker connections, dip switches for input routing, and more. The unit is also equipped with two RJ45 connectors for use with JBL CSR-V in-wall volume controls (available separately).FEATURESFor Commercial and Industrial Use80W into 8 or 4 Ohm Loads10W Per Channel8 Input Channels, 2 Output ChannelUsable with 70 & 100V SystemsEuroblock Mic/Line & RCA InputsHi-Z & 27V Phantom Power SwitchesSleep Mode & 2 Auxiliary OutputsVoice Activated Ducking & Priority MuteSPECIFICATIONSKey SpecsNumber of Channels8 Input / 2 OutputAmplifier Power Rating4 Ohms / 8 Ohms: 80 W Peak per Channel (1 kHz, 0.5% THD) 10 W RMS per ChannelLoad Impedance / Voltage4 Ohms (Minimum) 70 V (60 Ohms Minimum) 100 V (120 Ohms Minimum)Audio I/O2x Block 5-Pin Balanced Line/Mic Input 6x Block 3-Pin Balanced Line/Mic Input 6x Stereo RCA 5-Pin Unbalanced Summed-Mono Input 2x Block 3-Pin Balanced Aux OutputRackmount Size1 UAmplifierForm Factor/TypeRackmountNumber of Channels8 Input / 2 OutputAmplifier Power Rating4 Ohms / 8 Ohms: 80 W Peak per Channel (1 kHz, 0.5% THD) 10 W RMS per ChannelLoad Impedance / Voltage4 Ohms (Minimum) 70 V (60 Ohms Minimum) 100 V (120 Ohms Minimum)PerformanceFrequency ResponseAmplifier: 20 Hz to 20 kHz ±2 dB (Low-Z) 80 Hz to 15 kHz ±2 dB (70/100 V) Line Output: 20 Hz to 20 kHz ±1 dBInput SensitivityMic: 3 mVrms Line: 775 mVrms RCA: 300 mVrmsI/O ImpedanceMic Input: 400 Ohms Line Input: 20 Kilohms (Balanced) RCA Input: 50 KilohmsOutput LevelLine Output: 5 Vrms (10-Kilohm Load)Insertion Loss1 dB MaximumSNR> 90 dBTHD< 0.5% (20 Hz to 20 kHz, Main Output) 0.05% (Line Output)Crosstalk-70 dB (1 kHz)Signal ProcessingEQ2-BandConnectivityAudio I/O2x Block 5-Pin Balanced Line/Mic Input 6x Block 3-Pin Balanced Line/Mic Input 6x Stereo RCA 5-Pin Unbalanced Summed-Mono Input 2x Block 3-Pin Balanced Aux OutputOther I/O2x RJ45 Remote/VolumePhantom Power27 VDCPowerAC Input Power100 to 240 VAC, 50 / 60 HzAC Power Connector1x IECPhysicalRackmount Size1 UOperating Conditions32 to 95°F / 0 to 35°C up to 95% HumidityStorage Conditions-4 to 185°F / -20 to 85°CDimensions17.2 x 1.7 x 11.9″ / 436.9 x 43.2 x 302.3 mmWeight11.9 lb / 5.4 kgPackaging InfoPackage Weight16 lbBox Dimensions (LxWxH)20.5 x 16.3 x 5.2″
