Description of CSMA280:

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).

This Commercial Series mixer/amplifier boasts such features as voice activating ducking (useful for paging over background music), priority muting for channels one and five, and a sleep mode which automatically powers down the unit when no audible signal has been received for longer than 30 minutes. Also, with two auxiliary outputs, you may connect to an additional amplifier, though the master volume and tone controls will have no bearing on the resulting signal.

Channel Modes

8 inputs with 2 outputs of 80W of power.

Controls

Independent Bass and Treble controls for each output channel.
Input level and output volume controls.

Hi-Z Switch

The Hi-Z switch will switch in the built-in output transformer allowing the unit to drive 70V or 100V speaker systems directly when connected to the appropriate output terminals.

Phantom Power

Phantom power (27 V) can be applied to all mic inputs by turning on Phantom Power within the dip switches.

VOX Function

Voice activated ducking is available on input channel 1 and channel 5. The audio input level required to activate ducking is set using the trim pot on the rear panel. Adjusting in the counter-clockwise direction will reduce that level, while the full clockwise setting will disable the VOX function.

Priority Muting

Channels one and five may be used as priority channels, muting all other channels when pins 4 and 5 are shorted using a switch closure. If the amplifier has entered sleep mode due to inactivity, invoking priority will also bring the unit out of sleep and ready for transmitting an announcement.

Remote Volume Control

Remote volume control can be implemented using a CSR-V controller connected via an Ethernet cable to the RJ45 connector on the back panel.

Sleep Mode

This unit is designed to go into sleep mode after approximately 30 minutes operating with no signal at any of the inputs. Return of signal (-40 dBu or 7.75mVRMS) to any input will wake the unit. Also, a switch closure across the priority input pins will return the unit to normal operating mode.

AUX output

An auxiliary output that you may connect to additional amplifiers is available. The audio signal is the mix of the input channels. Note that the master volume control and tone controls will have no effect on the aux output signal.

Manufacturing

Crown's DriveCore technology
HARMAN's GreenEdge environmental standards

Certifications and Approvals

Lead-free RoHS standards, utilizing recycled metals, and using an energy-saving powder coat process
Energy Star certified

Play music everywhere with multi-room audio
Easily build your multiroom sound system with your existing AirPlay 2 speakers, Amazon Echo, and Google Home devices. Using your legacy audio devices, you can create a more flexible multiroom sound system with multiple WiiM Pros, WiiM Minis, or Linkplay-powered devices. WiiM Pro supports multiroom from various audio source inputs, including WiFi, BT, Aux, and SPDIF input, making it versatile with almost every music listening option.

Multiple EQ options
Cater to your listening taste by applying multiple EQ options including the 26 preset EQs, bass/treble adjustment, 10-band graphic EQ and parametric EQ.

Automate your routines
Make your life easier by automating your routines. For your sleeping and wake-up routines, create a routine to wake up or fall asleep to your favorite music, station, or podcasts. Or, use your Alexa to create routines.

Works with Siri, Alexa, and Google voice Assistants
Use your favorite voice assistants to select music, control playback volume, and more.

High-Res audio
Offering more streaming services and audio content that incorporate MP3 quality, lossless audio, or immersive sound technologies for their listeners. WiiM devices provide the capability to play Hi-Res lossless audio contents from Spotify, Amazon Music, TIDAL, Deezer, Qobuz and more. It supports up to 192kHz, 24-bit audio output which is the same as artist's recording in the studio . The integrated TI stereo DAC provides the high quality analog audio output with the 106-dB SNR, dynamic range and -92dB THD+N performance, outstanding in all audio categories.

Multiroom and stereo pairing
Playing music in your whole house is achieved with the perfect audio synchronization and seamless device control via the companion App . With careful hardware, algorithm and software optimization, we can achieve less than 150uS (0.00015s) synchronization accuracy among speakers as long as the speakers are in the same wireless network. Thus, your speaker system can be located wherever your Wi-Fi network covers. In addition, you can join two speakers connected with WiiM Pro or Mini as a stereo pair for a wider, more immersive sound stage. It also supports multi-room and for the various audio inputs such as Wi-Fi based streaming music, BT and analog/digital audio input via Line In or optical in. Thus, it can work with most of your music listening options.

Gapless Playback
Precise gapless playback is important to your listening experience. With precise gapless playback, the playback timing is guaranteed to be identical to the source. It's not allowed to introduce gaps or overlaps (crossfading) between successive tracks. The gap will be very noticeable in " continous " music such as live concert recording, some classical music etc. Various software, firmware and hardware components may add up to a substantial delay associated with starting playback of track. Our player uses two decoders to remove the extra samples at the beginning and end of each file, and combine them. It works for all the supported music services and music in your phone or local network

Adaptive EQ
Breakthrough listening experience requires both high-res audio contents and high quality playback device . When adaptive EQ is enabled, the music genre information and other tags included in the audio content are used to adjust the frequency in real time -either bringing rich audio to capture every music detail or making human voices clearer in the podcast.

Auto calibration of audio delay
The connected receiver or speaker may have different audio path latency due to different hardware, software and DSP processing. To maintain the synchronization of each system, it's desirable to measure the audio path delay automatically. By leveraging the on-device microphone and proprietary algorithm, the entire audio path latency is measured automatically when it's connected with the receiver or speaker. The latency value will be used to maintain the perfect audio synchronization in wireless multi-room playback with HomePod, Echo, Google Home or other WiiM devices.
