Networked PIP Series
In addition to these unavoidable delays, additional delay can be added to each channel.
Each channel is capable of 2.0 seconds of delay in 20.8 µs increments.
Overall delay = inherent delay + coarse delay + fine delay.
5.3.4 Noise Generator
Each channel has an independent uncorrelated noise generator that allows noise to be
mixed into the audio signal. This is useful for noise masking applications and testing. Each
channel has the following controls:
• Noise On/Off: The channel's noise generator can be independently turned on.
• Noise Type: Full spectrum white noise or pink noise.
• Noise Level: A fader to allow the noise level to be controlled.
5.3.5 Sine-wave Generator
A sine-wave signal generator allows the mixing of a single tone into the audio signal. Typi-
cal applications can be for the injection of a high frequency tone (19kHz) into the signal in
paging type system to continually drive the speaker, allowing continuous monitoring of the
speaker load. The following controls exist:
• Sine On/Off: The sine-wave signal generator's function.
• Sine Frequency: Controllable from 20Hz to 20kHz.
• Sine Level: Each channel's sine-wave signal level can be independently controlled.
5.3.6 SLM (System and Load Monitoring) Tab of the Control Panel
This function is available only in IQwic, not in System Architect v1.0. Also, it is available for
the PIP-USP3 and PIP-USP3/CN, but not for the PIP-Lite.
