- (1) JBL CSMA240 Commercial/Restaurant 2 x 40w Amplifier 4ohm/8ohm/70V/100V, 8 inputs
- (4) Rockville WET-D4 White Dual 4" Indoor/Outdoor Commercial/Restaurant 70V Speaker
Description:
Designed for commercial and industrial use, the CSMA 240 Commercial Series Mixer/Amplifier from JBL is a mixer/amplifier with eight mixer-channel inputs and two output channels. It's capable of reaching 40W of peak power with 5W 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 40W 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.

Description:
The WET-D4 is a dual 4” speaker that is perfect for restaurants, patios, conference rooms, and much more. The dual speaker design disperses the sound wider so you can evenly spread the sound in any room. The WET-D4 has a built in 70V transformer that can be tapped as low as 5 watts and as high as 30 watts! This wide range of wattage taps makes this perfect for main bar speakers, hallway speakers, seating areas, patios, and everything in between.
Our installation bracket is great because it has multiple angles for mounting the speaker. Once installed at your preferred angle the speaker is sturdy and will not move. The sound these speakers produce are both rich and full. They include large 9.75 oz magnets and the tweeter is an audiophile grade silk soft dome tweeter. We also have a built in 2nd order 2500Hz fixed crossover that protects the speaker and creates a great sound curve for any room. The 5-way binding post terminals give you many options such as regular speaker wire, spade terminals, and banana plugs. There is a tap switch on the speaker so you can easily select how many watts you want the speaker to get from the amplifier.

What is 70 volt ?
70 volt systems are the number one choice for applications where you want to install many speakers. With 70 volt there are a lot of advantages over 8-ohm systems. One of the main advantages is the simplicity of the wiring as well as how easy it is to match up speakers with the amplifier. For example, you can buy one 70V amplifier with 350 watts and you can install speakers that total close to 300 watts. It does not matter if it is 15 speakers that are 20 watts each or 50 speakers that are tapped at 5 watts each. You always want your 70 volt amp to have at least 15 or 20% more power than the combined watts your speakers are tapped at. When we say the word tap, what we are referring to are the knob on the rear of the speaker. For example, these speakers have selectable options of 5w, 10w, 15w, 30w. What this does is limit how many watts the built-in transformer on the speaker will allow the speaker to get from the amplifier. This gives you full customization over the sound for your space. In a restaurant for example you can tap your dining room speakers at 10 watts, the speakers by the bar area at 30 watts, and the ones in the hallway at 5 watts. Another great feature with 70 volt is you can mix and match any 70 volt speakers whether they are ceiling speakers, wall mounted speakers, subwoofers, etc.
70 volt systems allow you to run very long lines of speaker wire without signal loss. This is ideal when running long speaker leads. The wiring is simple. You just wire all the positive terminals of the speakers to the positive 70 volt terminals of the amplifier. The negative terminals on the speaker simply get wired to the negative terminals on the amp. You do not have to worry about impedance. The power is constant.
