PDA Pro-Range technical specifications
POWER
230-240 V a.c. mains (PDA200/2 <150 VA; PDA500/2 <225 VA; PDA1000/2 <300 VA)
(IEC 320 fused mains lead supplied)
INPUTS
Line (3 pin XLR type)
Input impedance: 6k8 + or – input to ground.
Sensitivity: 200mV – 2.5V RMS balanced or unbalanced.
Microphones (3 pin XLR type)
Input impedance: 6k8 + or – input to ground.
Sensitivity: 1 – 8 mV balanced
Phantom power: 12V switchable (on/off)
Outreach (Four-way Weidmuller connector. Plug type BL5. 08/4)
Input impedance: >10k
Sensitivity: 500mV - 6V RMS balanced
Outreach Power: 16 – 21 V d.c. is available via the amplifier’s Outreach Socket. A self-resetting fuse
protects this output from any accidental overload.
OUTPUT
Type: Current mode.
Loop connector: Four way binding posts
Recommended loop impedance: 0.5 – 1 Ohm @ 1KHz. Will drive higher impedance loops with reduced
area of coverage.
Loop drive current @ 1 Ohm: PDA200/2 – 6A; PDA500/2 – 9A; PDA1000/2 – 12A.
Peak loop drive current (measured over 5mS integration time):
PDA200/2 - 8 Amps @ 1 Ohm, 13Amps @ 0.5 Ohm;
PDA500/2 – 12 Amps @ 1 Ohm, 19 Amps @ 0.5 Ohm;
PDA1000/2 – 14 Amps @ 1 Ohm, 24 Amps @ 0.5 Ohm
Recommended cable gauge: See graph on page 6.
Headphones: 3.5mm jack socket allows monitoring of the loop signal via >32 Ohm headphones.
COVERAGE
The table below gives the maximum area coverage for a 400mA/M field strength +/- 1dB.
PERFORMANCE
Frequency response: 20Hz – 14 KHz + - 3dB
Distortion: Less than 0.5 %
Signal to noise ratio: Better than –65dB any input
