Output Screens
Refer to
Figure 19
Each output or group of outputs has a dedicated screen.
1. GAIN – The amount of gain applied to the input signal. Controlled by the GAIN knob on
the front panel of the amplifi er, or the GAIN control in the CXD-Q Output component in
the Q-SYS Design.
2. INPUT – The level of the audio signal applied to the CXD-Q Output component in the
Q-SYS design. The CXD-Q Output component is the connection to the output section of
the amplifi er. This meter reading can be changed from RMS to Peak in the Amplifi er Out
component in the Q-SYS design.
3. VOLTAGE - The voltage being delivered to the loudspeaker. This reading can be RMS or
Peak depending on the Meter Select setting in the Q-SYS design for the associated channel.
4. POWER – The power of the amplifi er / loudspeaker circuit. This reading can be RMS or Peak depending on the Meter Select setting in the Q-SYS
design for the associated channel.
5. HEADROOM – The amount of room left before reaching the amplifi er's maximum capabilities.
6. DAC LIMIT – When illuminated, this indicates that the signal to the D to A Converter is larger than can be reproduced and a limiter has been
engaged to prevent clipping. This is an indication that the gain structure is not correct.
7. PROTECT – When illuminated, this indicates that the channel is in Protect Mode. Usually due to driving too low of an impedance for too long.
8. LIMIT – When illuminated, this indicates the amplifi er limiter is active. This occurs if the signal is driving the power, current, or voltage above the
amplifi er rated values or due to thermal limiting.
Output Gains Screen
Refer to
Figure 20
The Output Gains screen provides a quick overview of all outputs and is the screen on which
GAIN adjustments are made.
Use the NEXT or PREV buttons to access this screen or, press one or more of the SEL buttons
to access the screen and make GAIN adjustments for the selected channels.
1. The highlighted background indicates that the Channel is selected by the SEL button.
2. Channel – the channels display according to the confi guration of the amplifi er.
3. Output Gain – the output gain is controlled by the GAIN knob on the amplifi er or with the
Gain control in the CXD-Q Output component in the Q-SYS design.
4. Q-LAN Input Level – the level of the audio signal applied to the CXD-Q Output component
in the Q-SYS design. The CXD-Q Output component is the connection to the output section of the amplifi er.
5. Voltage – The voltage applied to that output.
6. Output B is combined in parallel with Output A, the slot for Output B is removed.
