A15HP - In-Line High Pass Filter
$90.66

The Shure A15HP is an In-Line High Pass Filter. Balanced XLR in-line filter that reduces low frequencies below 100 Hz. The Shure A15HP in-line filter passes mid and high frequencies while reducing low frequencies. The A15HP helps to eliminate electrical and mechanical noise in an audio system such as 60Hz electrical hum from AC power lines, low-frequency rumble caused by wind noise or air conditioning system, and stage/floor noise transmitted to a microphone through the microphone stand. The A15HP affects frequencies below 100 Hz. When connected to the microphone input on a typical mixer (800 ohms impedance or higher), the A15HP reduces low frequencies by 12dB per octave. Female XLR to male XLR connector.

The Shure A15PRS is a Switchable Phase Reverser. Reverses the phase (polarity) of a balanced audio signal. The Shure A15PRS reverses the phase (polarity) of a balanced audio signal. Typical use applications include correcting polarity reversal caused by a wiring error in a microphone cable; connecting an unbalanced high impedance microphone having the "hot" signal on pin 3 to the input of a mixer that requires the "hot" signal on pin 2; and reducing phase cancellation/comb filtering between two signals that are of opposite polarity. An in-line switch permits instant selection of either normal or reversed polarity for comparison purposes.
