Compact4 speaker/amplifier with two integral radio microphone receivers, for operation on mains or rechargeable battery. Supplied as a system kit with two handheld radio microphone transmitters.


For audiences of approx 150 people: 

The Compact4 speaker/amplifier unit is ideal for public address applications. It has two radio microphone receivers and two other inputs.

The Compact4 is the 40-watt big brother of the MICRO. The amplifier is battery-powered with an intelligent charging circuit. Just plug it into the mains to re-charge. It has been designed to provide exceptional clarity and intelligibility of speech.

The amplifier is easy to use, requires no technical expertise and can be quickly moved anywhere inside or outside a building without the need to find a mains socket. It really is a plug and play (or listen in our case) product. 

The controls are kept to a bare minimum for ease of operation. 

Audiences of 150 or more can be addressed with ease, although a second unit  on the other side of the room gives a more balanced sound.

The amplifier weighs approximately 11Kg and has an underside top hat fitting for mounting on a standard speaker tripod stand (available for purchase separately).

There are separate inputs for a cable microphone and for a line level input (CD player, iPod or other sound source) with individual volume controls for each input.

For tone adjustment there are are Bass and Speech Clarity controls. 

There is a link IN/OUT connection socket which can be used to connect this unit to another Compact4 with built-in radio microphone receiver(s) for use as an extension speaker. The sound from the inputs of either Compact4 units will be heard from both Compact4s.

The Compact4 will run for up to 12 hours on its internal battery. The unit can be used on mains power while being charged.

40 watts, rechargeable battery/mains powered.

SoundRanger Compact4 kit with 2 handheld radio mics (40SFK4D)

Reviewed by: Karen Cssef from Aldershot

Stepping outside my house and a few blocks away from our local school, you can imagine my level of happiness to be able to hear the school using the Sound Ranger that we have on trial from you at the moment. I was shocked at the distance that the sound travelled and how fab the quality of sound was.

Thank you Phil for coming to set it up. Sports Day with a megaphone days are GONE. I don't think it will be long before our charity is getting the cheque book out to buy the Sound Ranger.

It was used today for the PTA Summer Fayre. Big thumbs up from them too. The PA system from the DJ microphone was used at times and kept cutting out............... oh my wow, the difference is amazing.
