The P8056 is a multiple volume control for 50, 70 and 100 V constant-voltage lines, suitable for rack mounting (1 modular unit). It consists of 6 inductive attenuators with 11 positions each (10 + Off), and each of which can bear a maximum load of 50 W. The six output lines (zones) can be split up into two groups of three each so as to drive them with one amplifier or two separate ones. Each attenuator has a bypass relay for sending out announcements and messages without any attenuation. Each relay requires a 24 VDC power supply, with absorption of 10 mA. The rear terminal blocks are of the removable type with slide-type fixtures.

FUNCTIONAL FEATURES

• Six 50-W attenuators
• 6 output lines separable into two groups of three each
• 2 inputs for constant-voltage lines (one for outputs 1, 2 and 3 and the other for outputs 4, 5 and 6)
• One bypass relay for each attenuator
• Can be mounted in a standard 19” rack (height: 1 U)
