APPENDIX C: JM-1P SPECIFICATIONS
40
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 producing +20 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/H)
Output Power 1275 W total (1 x 1000 W, 1 x 275 W)
Note: Wattage rating is based on the maximum unclipped burst sine-wave rms
voltage the amplifier will produce into the nominal load impedance.
Total Output 2550 W peak
Note: Peak power based on the maximum unclipped peak voltage that the amplifier will
produce for at least 100 milliseconds into the nominal load impedance.
THD, IM TIM <.02%
Load Capacity 2 Ω low channel, 8 Ω high channel
Cooling Convection at low to mid audio levels; fan-assisted only at high audio levels
Note: The fan is controlled by audio level, remaining off at turn-on and at low to mid
audio levels and operating only at high audio levels, making it virtually inaudible.
AC POWER
Connectors PowerCon with loop output or VEAM all-in-one (integrates AC power, audio, and net-
work)
Voltage Selection Automatic, two ranges, each with high-low voltage tap (uninterrupted)
Safety Agency Rated
Operating Voltage
95–125 V AC; 208–235 V AC; 50/60 Hz
Turn On/Turn Off
Points
85–134 V AC; 165–264 V AC
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 0.50 A rms (115 V AC); 0.28 A rms (230 V AC); 0.56 A rms (100 V AC)
Maximum Long-Term
Continuous Current
4.55 A rms (115 V AC); 2.50 A rms (230 V AC); 5.25 A rms (100 V AC)
Burst Current 8.0 A rms (115 V AC); 4.1 A rms (230 V AC); 9.2 A rms (100 V AC)
Note: AC power cabling must be of sufficient gauge so that under burst current rms con-
ditions, cable transmission losses do not drop voltage below specified operating range at
the speaker.
Ultimate Short-Term
Peak Current
20.8 A peak (115 V AC); 13.0 A peak (230 V AC); 21.6 A peak (100 V AC)
Inrush Current 7.1 A peak (115 V AC); 8.4 A peak (230 V AC); 7.1 A peak (100 V AC)
Note: Current draw for a single loudspeaker. Loop output not used.
