RDL STP-1 Universal Audio Attenuator 2 Channel

Universal Audio Attenuator - 2 Channel The STP-1 is a pair of convenient attenuator pads that can be located at the precise location that attenuation is needed. The low-cost STP-1 eliminates the costly labor of figuring and assembling fixed pads. Multi-turn trimmers in the STP-1 permit precise adjustment of levels without the need to connect any jumpers or external resistors. The STP-1 operates in either high or low impedance, balanced or unbalanced circuits. The wiring legend is printed on the case for easy installation.Features: Audio Level Attenuation Adjust Audio Level into Equipment Preset Audio Levels Precisely Match Audio Levels Increase Audio Input Headroom Two Adjustable Attenuators in One Package Specifications: Nominal Impedance: HI-Z 10 kΩ; LO-Z 600 Ω Adjustment: Screwdriver trimming adjustment, 15 turns continuous Circuit Type: Passive modified H & T pads Connections: Terminal block accepts 14 to 24 guage wire; no lugs required; input/output connection legend located on STP-1 Maximum Signal Inputs: HI-Z Balanced Line: +33 dBu, 35 V rms LO-Z Balanced Line: +27 dBu, 18 V rms HI-Z Unbalanced Line: +35 dBV, 45 V rms Reference Levels:Line level is +10 dBu to -10 dBu Mic level is -45 dBu to -65 dBu Power Requirement: Passive (not required) Ambient Operating Environment:-20 C to 60 C
