dpFX Pedals - Dual Loop Stereo Parallel Blender (+Tails / Ground Lift / Phase Reverse)

"dpFX Pedals" builds handmade and custom effects (dpeffects.com) . All products are serial numbered

--- This is the Dual Loop Stereo Parallel Blender ----
an all analog Stereo Parallel Blender that offers two independent loops and a dry blend as well and is able to handle signals varying from instrument level up to higher line level (~24Vpp max). All jacks are TRS (Tip=Left, Ring=Right, Sleeve=Ground). The device is compatible with mono signals as well.

Function explanation:   (check photos for schematic/flow chart)

• The stereo signal is taken from the INPUT and is split into three separate (stereo) signals.
• One is sent to Loop-A (SND-A), the other to Loop-B (SND-B) while the third is the DRY signal which stays intact.
• The signal from the Loop-Return (RTN-A, RTN-B) is then fed back to the circuit: first to the Phase Select section, then to the Volume section.
• The two Loop-Return signals are then mixed together with the DRY signal and sent to the OUTPUT.

- Footswitches A, B turn the respective loop ON/OFF
- Tails switches are for both Loops allow you to choose if the footswitches A, B will mute the SEND or the RETURN for each loop.
- Phase reverse switches are available for both Loops.
- Ground lift switches have been added on both Loops that may come in handy if you experience ground hum. They both lift the ground on the return jacks.
- The footswitch at the right corner completely bypasses the circuit (true bypass).

The device is also compatible with MONO signals. If you want the mono signal to expand in stereo and appear in both L & R channels in the output you'll just have to use a TS 1/4" to TRS 1/4" Adaptor cable that will tie the Tip of the TS to both the Tip and Ring of the TRS.

NOTE: if you plug a TS jacks at the input the mono signal will only appear on the Left (L) channel of the Stereo Output.
