APPENDIX C: UPJUNIOR SPECIFICATIONS
40
RF Filter Common mode: 425 kHz
Differential mode: 142 kHz
TIM Filter <80 kHz, integral to signal processing
Nominal Input Sensi-
tivity 0 dBV (1 V rms, 1.4 V peak) continuous average is typically the onset of limiting for
noise and music
Input Level Audio source must be capable of pro20 dBV (10 V rms, 14 V peak) into 600
Ω
to produce maximum peak SPL over the operating bandwidth of the loudspeaker
AMPLIFIER
Type Two-channel complementary MOSFET output stages (class AB/bridged)
Output Power 300 W total
Note: Wattage rating is based on the maximum unclipped burst sine-wave rms volt-
age the amplifier will produce into the nominal load impedance — low and high chan-
nels 30 V rms (42 V peak) into load impedance.

Cooling Forced air cooling over amplifier heatsink
AC POWER
Connectors PowerCon with looping output
Voltage Selection Automatic
Safety Agency Rated
Operating Voltage 100–240 V AC; 50/60 Hz
Turn On/Turn Off
Points 90–264 V AC; 50/60 Hz
Note: No automatic turn-off voltages. Voltages above 265 V AC are fuse protected but may cause permanent
damage to the power supply. Voltages below 90 V AC may result in intermittent operation.
Current Draw
Idle Current 0.448 A rms (115 V AC); 0.285 A rms (230 V AC); 0.497 A rms (100 V AC)
Maximum Long-Term
Continuous Current 2.55 A rms (115 V AC); 1.55 A rms (230 V AC); 2.75 A rms (100 V AC)
Burst Current 2.9 A rms (115 V AC); 1.7 A rms (230 V AC); 3.2 A rms (100 V AC)
Ultimate Short-Term
Peak Current 12.0 A peak (115 V AC); 9.0 A peak (230 V AC); 13.0 A peak (100 V AC)
Inrush Current 15.0 A peak (115 V AC); 13.0 A peak (230 V AC); 15.0 A peak (100 V AC)
Note: Current draw for a single loudspeaker. Loop output not used.
