An analog audio signal derived from a vinyl recording is processed via an input transducer, such as a moving magnet or moving coil device. A phono input stage (209) has an adjustable input impedance. A pre-amplifier (207) with variable gain amplifies an output from the phono stage. A power amplifier (201) amplifies an output from the pre-amplifier. The temperature of the power amplifier is monitored and an output (202) from the power amplifier is supplied to an output transducer. A touch sensitive screen (104) receives input gestures to provide control signals to a control processor (203). The control processor operates first relays to control the input impedance, operates second relays to control the adjustable gain and also operates the second relays in order to attenuate output volume in response to identifying the monitored temperature as being above a predetermined threshold.

Characterizing virgin tape cartridges in a characterization tape library and then sending the characterized tape cartridges to an end-user's library saves time and effort at the end-user's site. A characterized tape cartridge can be universally used in any compatible tape library if the virgin tape cartridge is characterized in a target calibration window that is within a specific range of heat and humidity. A calibration library can act as a ‘middleman’ receiving a virgin tape cartridge directly from an OEM. The virgin tape cartridge can be characterized followed by storing a record of the calibration in the tape cartridge's MAM while in the calibration library. The now post-characterized tape cartridge is then on to a user's tape library for use instead of just simply sending a virgin tape cartridge to the end user's library. The record in the MAM effectively changes the designation of the virgin tape cartridge to a post-calibrated tape cartridge.

Disclosed herein are information capture systems and related methods. An information capture system includes a sensor secured to an object configured to be involved with a possible event. The sensor is configured to detect one or more stimuli that are associated with the possible event, and transmit a sensor signal indicating data corresponding to the one or more stimuli. The information capture system also includes a recording device configured to record information responsive to a triggering event determined from the sensor signal. A method includes analyzing sensor data from the sensor, determining, from the sensor data, that a triggering event occurred, and recording post-trigger information following the determination of the triggering event.
