4.6.2 Test Tone Type
Selects either a Sine wave tone or Pink Noise.
4.6.3 Test Tone Frequency
Adjusts the frequency of the test tone. Range is from 20 Hz to 20 kHz. From 20 Hz to 1
kHz, the generator is adjustable in 10 Hz increments. From 1 kHz to 20 kHz, the incre-
ments are 100 Hz.
4.6.4 Test Amplitude
Adjusts the level for the tone/noise generator.
4.7 Analog Control
• Analog Headroom Adjusment: Allows up to 10 dB of attenuation to be applied to
all channels at the analog output.
• Analog Trim (Left through RoRt): Allows up to 10dB of attenuation to be applied
in 0.5dB steps individually to each analog output channel. These values are stored for
recall during power-up. These channel trims are used to calibrate a listening environ-
ment
after first adjusting power amplifiers or powered speakers (see below).
• Analog Mute (Left through RoRt): Allows individual muting of output channels.
This is useful for troubleshooting and channel ID use. Note that these values are not
saved and will return to their normal un-muted state when the unit is power cycled.
4.8 Communication
Setup of TCP/IP parameters can be done in this menu group
4.9 System
Selective reset to factory defaults can be performed in this menu group.
4.10 Monitor Calibration (Analog Outputs)
The Linear Acoustic UPMAX v4 is supplied with a monitoring grade digital-to-analog con-
verter that provides balanced outputs of all eight audio channels. The level of these outputs
can be controlled by the front panel rotary encoder or from an external volume control (a
high quality “big knob” remote is available from Linear Acoustic).
The individual channels can be calibrated over a 10-dB range to allow matching the unit to
