1kHz Tone (Optional)
If your BG-3 or BG-7 was orders with the optional 1kHz tone feature, you will see another
connector on the rear panel. There are two (2) types of Tone Option, Balanced and
Unbalanced. Both options output 1kHz (+/- 100Hz) audio tone at 2Vp-p (+/- 0.2Vp-p). If
Unbalanced Tone has been installed then an RCA (phono style) connector has been installed.
If Balanced Tone has been installed then a male Mini-XLR connector has been installed. This
connector is wired the same as a standard XLR audio connector (pin 1 = ground, pin 2 =
negative, and pin 3 = positive). The Mini-XLR connector was chosen due to space constraints
on the rear panel.
