Specifications
■
The headphone/speakers jack has an output level of 1.75 Vpp into a 4-ohm load, and
2 Vpp into a 10-kohm load.
■
The integral microphone is a directional microphone, optimized for use with speech
recognition programs. It is particularly effective in noisy office environments.
■
The display accepts an audio input signal of up to 4 Vpp (line level, low sensitivity),
or as low as 20 mVpp (microphone level, high sensitivity) without clipping the signal.
