Primary speaker duties, called "FOH" or Front of House speakers by sound reinforcement professionals, are handled by Patrick's Carvin PM15A powered, bi-amplified, two-way loudspeakers. These speakers contain their own internal amplifiers, meaning they can significantly boost even a low power input signal. The Carvins are elevated to roughly head height by sturdy "Ultimate Support" tripod stands.
Initially, the heart of our P.A. system was Jeff's Behringer PMH880S 10-channel stereo powered mixer. One of the most powerful of its type available, it offers some very useful features, such as two independent effects processors, dual graphic equalizers to fine-tune our vocals, and a feedback detection system. We used the Behringer for practices until it moved on to a new home in August, 2010.
Microphones complete the PA setup. Patrick and Jeff each use Electro-voice N/D767a supercardioid microphones like the one pictured. Very popular with professional performers, these mics use a neodymium-based magnet structure, and offer an unusually wide frequency response of 35-22 kHz to ensure vocal clarity.
. Jeff sometimes uses a Audio-Technica ATM-710 condenser stage microphone. While providing superior clarity and sound quality, condenser mics can be tricky in noisy environments - they can promote unpleasant feedback in some situations.
Rob uses a Audix OM-2 microphone, which handles sound pressure levels of as much as 140db, making it a perfect complement to Rob's powerful vocal style. With a frequency response of 50-16 kHz, this hypercardioid mic captures Rob's singing, while rejecting the very low and very high frequency sounds that emerge from his drums and cymbals.
