SYSTEM HEADROOM
The System Headroom menu displays for each channel (selected by the top buttons Ch.1 to Ch.4) the
headroom available from both the amplifier channel and the speakers connected to it.
On the amplifier headroom monitoring part, two vu-meters with a 60 dB scale are displaying the Output
Voltage and the Output Current, both referring to 0 dB being the maximum voltage of the maximum current
the amplifier can output. Please note that these maximum values are dependent on the NXAMPmk2 model.
On the speaker headroom monitoring part, three view meters with a 24 dB scale are displaying the
temperature of the voice coils of the connected speakers, the displacement of the membranes, both referring
to 0 dB being the maximum temperature and the maximum displacement the speakers can safely reach.
Please not that these maximum values are dependent on the speaker’s preset used.
The last view meter is showing how much the NXAMPmk2 is reducing the output level to protect the
speakers. This is a global meter displaying the maximum of all protections applied to the speaker, being a
frequency selective displacement protection using a VCEQ (Voltage Controlled EQ), a wideband thermal
protection for LF or HF driver for example, a peak limiter protection etc.
