SPWX

Analogue processor for stage monitoring

Analogue signal treatment
4 independent monitoring channels
Switchable to 3-channel + sub
Dedicated to DX12 and DX15 (+ SB115)

The APG SPWX processor is specifically dedicated to process the signal transmitted to the DX15 and/or DX12 loudspeakers. They integrate a set of electronic functions, allowing to optimize the frequency response, and the subsonic protection of the loudspeakers.

The SPWX controls either a set of 4 individual monitors or 2 individual ones (Ch. 1 & 2) and another monitor with a subwoofer (Ch. 3 & 4). In that case, the subwoofer signalled, delivered by Output 3, is derived from Input 4 and filtered accordingly. Each pair of channels (1/2 & 3/4) can be put in bypass, which inhibits and isolates the processor from the amps.
Each channel has a switch that allows the selection of DX12 or DX15.

Each channel includes a resonating high-pass filter, a low-pass filter, a shelving filter, and a 3-stage parametric equalizer. The “sub” line integrates a resonant high-pass filter, a 4th order Linkwitz-Riley low-pass filter (24 dB/Oct) and three active protection cells. In “Sub” mode, outputs 3 & 4 are filtered according to a 4th order Linkwitz-Riley function (24dB/Oct).
Each channel has a signal presence LED illuminating when the output signal is superior to -10 dBu. In sub mode, filtering of channel 3 is optimized for SB115, TB115B and TB118B model.
