Over the years we have updated our range of amplifiers to meet or exceed the requirements of BS7594 and EN60118-4 when correctly installed, all amplifiers in our range offer excellent intelligibility, true current mode amplification, phantom power (for electret microphones) and full compatibility with our ‘outreach plate’ audio input extension system (except the PL1, VL1 and DL50). Many are also available in kit format for ease of specification, purchase and installation.
