Technology Showcase: Powered Mixers

Flexible all-in-one mixers are ready to tour.
A new addition this year to the Peavey XR powered mixer series, the XR 1220P runs dual 600W Class D power amps that can be configured into five operating modes: left and right, left and right with subwoofer, main and monitor, main and monitor with subwoofer, and monitor 1 and 2. On subwoofer modes, a built-in fourth-order crossover sends all frequencies less than 100Hz to the subwoofer output channel. All 20 mic input channels provide both XLR mic input and 1/4in. line input connections along with a 1/4in. interstage patch point for outboard processing equipment. Each channel has an input gain adjustment, an 80Hz low-cut filter, two monitor sends, an effects send, and low/mid/high EQ adjustments. Peavey's proprietary Mid-Morph control adds crispness when turned clockwise and cuts harsh mid frequencies when turned counterclockwise. The master section features a 9-band digital EQ for the output channels, a realtime analyzer, and the Peavey Feedback Ferret—which can be assigned to either the left or right outputs, main and monitor, or monitor 1 and 2.
Phonic's Powerpod 885 Plus has two internal amplifiers that generate 400W into 4Ω each and are assignable to either the main left and right outputs or in mains and monitors mode. They can be switched into an 800W mono bridged mode as well. The mixer is housed in a carrying case similar in size and shape to a floor monitor. Each of the six mono input channels has a switchable 25dB pad and high- and low-impedance inputs. The two stereo channels have separate left and right 1/4in. line-level inputs along with an XLR input, and all have 3-band EQ, effects and monitor sends, main-level control, and pan pot. The board has dual digital effects processors with 16 preset programs and parameter control. Outputs include a record out with level-matching control, dual 7-band graphic EQ with a feedback detection system, and two built-in limiters. The system also has a wireless microphone module slot.
Pyle Audio designed the PMX1608 powered mixer with the input connections on the top, with the controls. Each of the 16 mono input channels has 3-band EQ, input attenuator, and output channel selection including main stereo and group stereo. The board also provides 48V phantom power, two 7-band graphic EQ sections, and a DSP feature with 16 effects. Total power output is 1200W into 4Ω, and the supply voltage is switchable between 110V and 220V.
