Palmer
RIVER saar

So, you want to play your guitar or your bass through two amps at the same time? Great idea! The problem is, it hums. And not just a little bit either. In fact, it makes a real racket. Thankfully, the Palmer saar Guitar Splitter box is here to save the day. The saar separates the ground potentials of both amplifiers and prevents ground loop hum when interconnecting multiple amps. 

The Palmer saar loops through the input signal passively to amp out 1, while an active FET switch branches off the signal for amp out 2. This happens without sound loss, as the FET input level is extremely high impedance. Amp out 2 is also decoupled from the ground circuit by a transformer. Ground loops can be separated by pressing the ground lift switch.  

The signal from amp out 2 is low impedance and reliable, so that longer cable runs without sound loss are also possible. An important feature is the phase reverse switch for the second output. The signal polarity of guitar/bass amplifiers is not standardised. Two amps operated simultaneously can be in-phase or out-of-phase. In the latter case, the sound is unpleasantly thin - which can be resolved by pressing the phase reverse switch on the Palmer saar. Of course, you can also use the phase reverse feature as a sound design tool if you wish: the out-of-phase sound can sometimes be a great creative option! 

The Palmer saar is a simple and effective tool that lets you enjoy the larger-than-life sound of two amps simultaneously - without any hum or interference.
