DigiMod 500/1000/1500/2000HV/1000NPS
WARNING!
Mains Connections details for Digimod 2000HV
In case of usage of not protected fast-on connectors, the minimum air distance between Earth
connection and mains energized fast-on body / blades, must be at least 2,5mm.
Single ended operation (stereo and bi-amp mode):
DigiMod output stage is designed to work in balanced supply mode.
This allows better exploitation of power supply capacitors and power supply dynamic.
This specific configuration lead to have CH2 in inverting operation respect to CH1.
For proper connection please follow the connecting instructions and consider that CH2 output
connector hot pole is the negative and the positive of the output is grounded (only for CH2).
Input stage of CH2 is designed to have reversed phase path to maintain overall not inverting
behaviour.
Bridge mode operation:
DigiMod1000/1500/NPS are capable to work in bridge mode on load nominal impedance down to 8
ohms, DigiMod2000HV on load nominal impedance down to 16 ohms
Output stage of the two channels is designed to work in balanced supply mode , that allows
better exploitation of power supply capacitors.
This specific configuration lead to have CH2 output stage inverting operation as previously
mentioned.
Bridge mode connection on inputs is performed directly paralleling the inputs without phase
reversing (INPUT+1 wired to INPUT+2 and INPUT-1 wired to INPUT-2).
Bridge mode connection on outputs is performed directly wiring the load between OUTPUT+1 and
OUTPUT-2.
Note:
It is important to respect the connection indications.
Do not to reverse output signal of CH2 to maintain grounded negative output on CH2.
Damage of the unit may occurr in case of equally phased outputs.
