| OBSERVACIONES | El previo de micro ISA One ofrece la prestigiosa tecnología ISA de preamplificación de micrófono basada en transformador alojada en un chasis robusto y portátil. Incluyendo la topología del módulo original ISA110, que formó parte de la legendaria consola Forte. Junto al previo hay entradas de línea y D.I con controles de ganancia dedicados, conmutadores de impedancia activa o pasiva y una salida en jack TRS para encaminar hacia un amplificador junto a un salida XLR independiente |
| CARACTERISTICAS TECNICAS | |
| Microfono Input | Rango Ganancia = 0dB to 60dB in 10dB steps + 20 dB of variable gain Input Impedance, variable as follows (Switched Impedance setting Equivalent Input Impedance at 1kHz) Low = 600 Ohms / ISA110 = 1400 Ohms / Med = 2400 Ohms / High = 6800 Ohms EIN (equivalent input noise) = -126dB measured at 60dB of gain with 150 Ohm terminating impedance and 22Hz/22kHz band-pass filter Noise at main output with gain at unity (0dB) = -97dBu measured with a 22Hz/22kHz band-pass filter Signal to noise ratio relative to max headroom (9dBu) = 106dB THD at medium gain (30dB) = 0.0009% measured with a 1kHz -20dBu input signal and with a 22Hz/22kHz band-pass filter Frequency response at minimum gain (0dB) = -0.5dB down at 10Hz and -3dB down at 125kHz Frequency response at maximum gain (60dB) = -3dB down at 16Hz and -3dB down 118kHz CMRR=98dB (Channel 1, 1kHz, maximum gain with +24 dBu input) Crosstalk Channel to Channel: with 10dB@1kHz input to chA, chB output =104dBrA. With 10dB@10kHz input to chA, chB output = 84dBrA |
| Linea Input | Ganancia Rango = -20dB to +10dB in 10dB steps + 20 dB of variable gain Input Impedance = 10k? from 10Hz to 200kHz Noise at main output with gain at unity (0dB) = -96dBu measured with a 22Hz/22kHz band-pass filter Signal to noise ratio relative to max headroom (24dBu)=120dB Signal to noise ratio relative to 0dBFS (+22dBu) = 118dB THD at unity gain (0dB) = 0.001% measured with a 0dBu input signal and with a 22Hz/22kHz band-pass filter Frequency Response at unity gain (0dB) = -0.3dB down at 10Hz and -3dB down at 200kHz |
| Instrumento Input | Gain range = 10dB to 40dB continuously variable Input Impedance: High = greater than1M / Low =greater than 300k / Noise at minimum gain (+10dB) = -92dBu measured with a 22Hz/22kHz band-pass filter / Noise at maximum gain (+40dB) = -62dBu measured with a 22Hz/22kHz band-pass filter / THD at minimum gain (+10dB) = 0.001% measured with a 10dBu input signal and with a 22Hz/22kHz band-pass filter / Frequency Response at 10dB gain with -10dB input = 10Hz-100kHz +/- 0.6dB / Frequency Response at 40dB gain with -40dB input = -2.5dB down at 10Hz and 0dB at 100kHz |
| Filtro de Paso Alto | Roll off = 18dB per octave 3 pole filter Fixed Frequency 75Hz measured at the 3dB down point |
