OUTPUTS:
Headphone - four 1/4-inch stereo headphone jacks connected in parallel
- Peak to peak voltage is typically 50 volts into 100 ohms
- Power output is 3 watts RMS into any load from 4 to 100 ohms
- Output impedance less than .1 ohm
- Amps protected from overvoltage, undervoltage, overloads including shorts
to the supplies, thermal runaway and instantaneous temperature peaks.
- No power-down / power-up thumps, pops or DC
- Multi-mode MUTE button ("panic button")
Mic / Monitor
- brought out on "INPUT" ELCO only (not on LINK)
- output level +4 dBm nominal unbalanced
- output impedance < 50 ohms, will drive 500 ohm loads
GENERAL:
- THD + Noise < .03% (-70dB)
- IMD (SMPTE) < .03% (-70dB)
- Tone controls > +/- 12 dB @ 100 & 10K (gentle slope)
COMMUNICATION:
- Multimode TALKBACK. "TALK" over music, "INTerrupt" kills music
- DC control voltage enables individual stations to receive TB signal
- Built in MIC and TALK button, 2 LEDs show TB mode
- MIC and SWITCHED MIC signal available via ELCO input
