We have just spent two days at HMP Send, near Woking, in Surrey refitting all of the sound system in their sports hall and gym including the CV and resistance rooms
We installed 6 x Clever Acoustics BGS 85T in black driven by an Adastra A2 digital mixer amplifier which we performed a little magic on and converted the output to 100v line
A second Adastra A2 was used to power 4 x RCF 1 x 12″ wall mounted cabinets in the sports hall
Being a prison, devices such as mobile phones and portable media players and the like cannot be used so input sources were more traditional with an Adastra AD-400 CD player and a Manhatten Freeview box – the AD-400 has FM capability but, at present, the prison is using signal blocking technology which made this impossible to set-up
Wireless microphones were license free Channel 70 W Audio DTM 800 systems with two beltpack transmitters and Monacor HSE-86 headmics
