|
Gain at 1kHz:
85dB of gain at 1kHz, balanced-in to balanced-out in Microphone Input mode
Noise figure, rms A-weighted:
<2dB
Noise figure, rms unweighted:
<3dB, 20 kHz LPF bandwidth
EIN:
<-130 dBu A-weighted, 150 Ohm resistive source
THD:
-3dB <1Hz and >100 kHz <0.02% at 1 kHz
Input impedance:
63K Ohms (10K Ohms when P48 is engaged)
Input Gain control:
Twelve-position switch provides from +7dB to +63dB of gain for the preamplifier circuit, as measured between the input and the before the output line driver.
Switched LF Shelving filter:
12dB per octave from 100 Hz
Color LEDs:
Yellow, Green, Red
XLR output maximum level into 600Ω load:
+28 dBu, balanced; 0 dBu = 0.7746 V rms
XLR connectors polarity:
Pin-1 is ground, pin-2 is high, pin-3 is low
LED signal level indicators:
The green LED snaps on at -20 dBu to indicate the presence of signal; the yellow LED snaps on at 0 dBu; the red LED snaps on at +24 dBu to warn of approaching signal overload.

External Features:
An external switching power supply with a grounded AC plug is used with the TRP2 so hum fields can be kept away from the high-gain electronics. The power supply allows the TRP2 to be used in any country without any modifications made to the unit. The power supply uses a 5-pin XLR connector for its output. It has one 18 volt AC secondary winding, which is used within the TRP2 to provide three regulated DC voltages. Bi-polar 18-volt rails are provided for the electronics and a +12 volt rail for the Aeromat relays. Dimensions:
Size:
8.5” w, 8.5 d, 1.5” h (36.7 cm x 36.7 cm x 4.3 cm)
Weight:
2lbs oz (0.9 kg)
