The reason for this is the RF signal needs to bypass the audio circuitry in order to be properly processed by the demodulator.

They have acquired a reputation for very high quality for use in the signal path, and power supplies, of audio circuitry.

The sidetone audio is typically derived from the transmit audio circuitry.

The audio circuitry is the owner's responsibility.

The most basic interfaces use audio circuitry that is built into the computer motherboard.

Sound cards add better audio circuitry, a music synthesizer and a MIDI interface.

Bose has added a second set of microphones on the inside of the earcups, redesigned the earcup seal and further refined the audio circuitry.

Signal level emulation is used to emulate audio circuitry that consists of analog components.

Despite its more modest price, the Yamaha player offers excellent video quality and advanced audio circuitry featuring Yamaha's distinctive "hi-bit" technology to decode digital audio signals.

Naim's design philosophy is characterised by the incorporation of over-engineered power supplies to ensure fast and generous current delivery to the audio circuitry.
