The HP4 can be hooked to another processor, such as the 
COMP16 or TubePre in a live or studio environment. We do 
recommend that whenever possible, balanced cables be used. An 
example of a balanced cable would be a TRS (Tip – Ring – 
Sleeve). A balanced cable is preferred because it generally has a 
greater level of noise rejection. In other words it is less susceptible 
to outside interference.  

Use with a Console 

The HP4 can be connected to the headphone output of a 
console/mixer to multiply the headphone outputs. Care should be 
taken that the headphone output level of the console/mixer is not 
set to high. Setting the output level to the HP4 too loud, could 
cause the unit to distort. The monitor outputs are designed to be 
connected to the power amp of your studio speakers, to the inputs 
of self amplified speakers, or to another HP4.
