NTP

Cheers from Norway.
These Sandar line amps (-6 to +24 dB gain range) each has a single NTP M-100 as the only active component
The "Typical Ratings" for a NTP M-100 opamp says just 6,5 mA current consumption/draw for "no signal" mode.
What will the typical current consumption/draw be in "active" mode, i.e with the full +24 dB line gain?
I wonder if a Kniel linear PSU with +/-15V@500 mA capacity is sufficient to power 8 such line amp cards?

Current draw does not vary with gain. It varies with level and load.
For example, outputting +4dBu into 600 ohms results in a current increase of about 3mA.
Outputting continuously +24dBu into 600 ohms would draw 30 mA.

It should.
