The Walker W10 in-line amplifier is universally compatible and designed to increase incoming signals with up to 26 dB of gain above the normal level. Both units contain their own power source. The W10 is AC powered; it may be easily placed on a desktop and will work with virtually any standard or electronic phone, single or multi-line (except those with a dial pad in the handset). An added feature of the W10 is that it's lightweight, durable, and compact so it may be carried anywhere for ultimate convenience. Walker In-Line Amplifiers - W10 In-Line Amplifier - 3 kHz
