Radio Design Labs Radio Design Labs PT-AMG2 Portable Audio Signal Generator and Monitor

The 700 Hz oscillator section features two outputs. The balanced XLR output is front-panel switch selectable for MIC or LINE level ( pro level). The unbalanced output operates at -10 dBV ( consumer). Output stability is suited to accurate bench top audio testing. The audio metering circuit features two inputs, an LED meter and a monitor speaker. The balanced input is front-panel switch selectable for MIC or LINE input ( pro). The unbalanced input operates at -10 dBV ( consumer). Either input may be used to feed the metering circuit. For balanced +4 dBu inputs, meter 0 dB - +4 dBu. For unbalanced inputs, meter 0 dB - -10 dBV. A front-panel volume knob controls the speaker level. The IN PHASE LED illuminates when the oscillator output and metering input are in phase ( 0 dB level or greater). The PT-AMG2 operates either from two internal 9 volt batteries or from an external 12 Vdc to 30 Vdc supply. Test leads and bench top support bracket are included. The balanced line levels ( input and output) may be preset by the user to +4 dBu or +6 dBu.
