Expert Description
En: A resistive H-pad in an XLR barrel, sold in 10, 20, 30 and 40 dB versions; this record is the 20 dB one. Input 1 kohm, output 150 ohm — the resistors set both, which is why the attenuation is a design constant and not a load-dependent figure the way a transformer's insertion loss is. · Uk: Резистивний H-подільник у корпусі XLR, що продається в версіях на 10, 20, 30 і 40 дБ; цей запис — про 20 дБ. Вхід 1 кОм, вихід 150 Ом — обидва задають резистори, тому послаблення тут стала конструкції, а не число, залежне від навантаження, як втрати вставки трансформатора.·

Expert Audio Engineering Commentary

Production Warning

A resistive pad in an XLR line drops the phantom supply across the same resistors that drop the signal, so a condenser microphone downstream of one will usually not work. Whirlwind describe the part as an H-pad and say nothing about phantom; treat the line as dead for powering purposes unless you have measured otherwise.
