Connectivity
Atom Amp provides two inputs. Press the “INPUT” button to select 3. 5mm, or depress for RCA.
RCA Preamp Outputs are only active while headphones are unplugged. Set the “GAIN” button
to low gain (depressed) when using RCA output. The volume knob adjusts RCA output.
Gain Setting
VRMS (dBU)
Maximum RCA Analog Input Level (High Gain):
2.10 VRMS (+8.6 dBU)
Maximum RCA Analog Input Level (Low Gain):
8.65 VRMS (+20.1 dBU)
Setting Gain
Press the gain button to toggle between low or high gain amplification. Always use the lowest
gain necessary.
Switch to high gain only when you’re unable to achieve desired listening volume at low gain.
Source Safety
Atom Amp is DC coupled for maximum signal quality and requires an input source with <
4.5mV of DC offset for safe operation. All JDS Labs DACs and consumer audio sources are safe
to use.
If you experience warm headphones, a loud pop when changing gain, or severe rustling sounds
while adjusting volume, immediately power off and contact the manufacturer of your audio
source to ensure DC offset is below 4mV.
