Oscillators and Talkback Units

Apart from the audio level meter CH711 and the oscillator CH709 with frequency and level controls there is a talkback amplifier with 8 outputs, a talkback input mixer with noise gates and 8 inputs and a power amplifier for talkback and PFL speakers. Both the CH711 and the CH709 can handle levels of more than + 30 dBu.

Even though most of these modules are designed for custom consoles, all modules can be used in standard frames as well.
