Parallel Loop Blender, recording station (custom KRAMA)

Custom Parallel Blender (KRAMA)

Guitar/Bass Recording station

 Specifications:

▹ Two independent, parallel loops A, B (send A/B, return A/B)
▹ PAN between loops (A↔B)
▹ Dry blend
▹ Boost up to +12dB for A, B & Dry
▹ Phase reverse for A & B
▹ Standard TS jacks (6.35mm, 1/4")
▹ Three Balanced XLR outputs (out, A, B)
▹ Input impedance: 1MΩ (IN, RTN)
▹ Output impedance: 100Ω (OUT, SND)
▹ Internal voltage doubler circuit. It make use of the classic 9V supply to produce a dual rail supply that provides you more than enough headroom.
▹ Current draw: 185mA
▹ It can handle higher line level signals, up to ~20Vpp without distorting.

▹ Enclosure Dimensions: 188 x 120 x 39 mm (7.40 x 4.72 x 1.53 in)

 Below there is a flow-chart that explains the general idea:

Details:
KRAMA gives you the ability to split your signal, route it through two separate loops and blend them all together with your dry signal. The signal volume of the each loop (A,B) and the Dry signal can be controled independently through the pots A,B & DRY which also offer a boost up to +12dB.
PAN function offers you the ability to smoothly PAN from one loop to the other while keeping the dry signal unaffected.

Two phase reverse switches ensure that you will overcome any case of phase cancelation during the blending process when using pedals that reverse the phase. The phase reversal is applied after the signal enters the RETURN jacks.
The pedal is also equipped with balanced outputs (XLR) in case you want to route the output e.g. to a console.

KRAMA requires typical 9V power supply (center negative) that should be able to provide at least 185mA. Internally a separate circuit uses the 9V to produce a dual rail voltage supply that is necessary for the blender to work properly providing huge amounts of headroom, avoiding crosstalk and ensuring zero signal clipping even in high volumes.
[Do not exceed the recommended 9V supply voltage. It may damage the circuit.]

Useful Notes:
- To avoid hum, ground-loop buzz and other possible noises the use of an isolated power supply is recommended. Avoid powering KRAMA with the same power cord that other pedals are powered.
- In case you use this device to send the output in more than one amps be sure not to create any ground-loops because it will most likely generate noise. If you need isolation check our isolated-output products or contact us for more info.

Nomenclature:
KRAMA (Ancient Greek: Κρᾶμα) is the result of mixing two or more metals or other materials producing a somehow homogeneous mixture.
