Various implementations include portable speakers configured to adjust audio output based on detected input connections. In certain cases, a portable speaker includes: an enclosure housing: at least one electro-acoustic transducer for providing an audio output; a processor coupled with the transducer; an audio input module coupled with the processor for receiving audio input signals; and a battery configured to power the at least one transducer, the processor, and the audio input module; an input channel for receiving a hard-wired audio input connection; and at least one wireless input channel for receiving an audio input from a source device via a wireless connection, where the processor is configured to: adjust an audio signal received from the hard-wired audio input connection if a source device is already connected via the wireless connection.

Various implementations include portable speakers with detachable wireless transmitters. In some particular aspects, a portable speaker includes an enclosure housing: at least one electro-acoustic transducer for providing an audio output, a processor coupled with the at least one transducer; an audio input module coupled with the processor for receiving audio input signals; and an input channel for receiving a hard-wired audio input connection at the enclosure; at least one wireless transmitter detachably housed in the enclosure and in communication with a corresponding wireless input channel for receiving audio input from a source device.

Portable speaker with integrated wireless transmitter

A system for controlling the gain of an input signal in an audio signal amplifier. The system includes a user-operable gain control, and analog and digital circuit elements that together are configured to modify the gain of the input signal in response to the user-operable gain control.
