2.3.4 Speaker
A speaker is built into the QTERM-G75 terminal and faces to the back of the unit. Audio can
be linked to events or actions (e.g., screen press, timer, etc.). Pitch and duration of a sound are
controlled by API functions called from the user application. Refer to “Controlling the
Speaker” section in the Qlarity-based Terminal Programmer's Reference Manual.
Optionally, an audio (.wav) decoder can be added to the QTERM-G75 to allow the speaker to
play audio files. The audio decoder supports wave files meeting the following criteria:
• Sample rate of 8 kHz, 11.025 kHz, 16 kHz or 22.050 kHz
• Resolution of 8 or 16 bits per sample.
The audio decoder circuit amplifies the signal to 0.5 W rms at the speaker.
