Lake LM 26 Operation Manual page 25

LM 26 Input Mutes are displayed on the LCD screen in Input Meter Mode and are controlled using the
adjacent buttons and rotary encoder. The Input Mutes can also be viewed and changed via the front panel
I/O CONFIG Menu. Module Input and Output Mutes are controlled via the dedicated mute buttons under-
neath each channel's five-segment LED meter as shown in Figure 6-4.

6.8.1 Module Input and Output Mutes
The LM 26 provides dedicated mute buttons for the two module inputs (A/B) and six module outputs (1>6)
as labelled in Figure 6-4. To mute or unmute a module input or output, tap the corresponding button. The
button is illuminated white when unmuted, and red when muted.
Refer to the Lake Controller Operation Manual for details of Module mute controls via the software.
6.8.2 Clip Indication
The dedicated 5-segment metering LEDs (Figure 6-4 ) display Module input and output clip or pre-clip
conditions. Additionally, the faults and warnings LED described in section provides clip warnings for LM 26
input mutes, or GPIO protective mutes, along with confirmation text on the LCD screen.
Clipping is monitored at the following positions in the signal chain:
▸ Analog Inputs: If the input signal exceeds either +12 dBu or +26 dBu (according to analog sensitivity
setting), a clip indication will be given. This does not apply if digital inputs are selected.
▸ Module Inputs: If the signal level at this point exceeds +25 dBu, a clip indication will be given.
▸
Module Outputs: If the signal level at this point exceeds +21 dBu, a clip indication will be given.
