Cue Clip The red Cue Clip LED lights whenever the Cue Mixer is overloaded. Clipping may eliminated by:
• turning down A TO CUE, B TO CUE, or C TO CUE knobs
• changing C IN configuration from L to H operating level
• turning down frequency-selective boost in the EQ
• trimming down the CUE IN level
• turning down the CUE VOL knob
NOTE: It is possible for the Preamp channels to be clipping but not overloading the Cue Mixer because the
A or B TO CUE knob is turned down. It is also possible for the Preamp to be operating normally but
clipping the Cue Mixer because the A or B TO CUE knob is turned up too high or there is too much EQ
boosting Preamp audio through the Cue Mixer.
CUE IN MUTE Switches off the CUE IN audio to the Cue Mixer outputs. Hold the switch 2 seconds
[Hold to Trim] to display the TRIM level of the CUE IN audio on the digital display. Use the -/+ keys to set the TRIM
amount through 4 gain levels [-6,0,6,12 dB]. The CUE IN trim display will turn itself off after no
adjustment has been made for 1 minute.
SPKR MUTE SPKR MUTE switches off audio to the SPKR OUT jack(s). This switch may affect the CUE
[Hold to Trim] OUT/Phones jack in one of 3 ways depending on configuration (see "Configuring the Remote Preamp"
below).
• CUE OUT always on - ignores SPKR MUTE switch (factory default)
• CUE OUT mutes with SPKR MUTE switch
• CUE OUT mutes opposite of SPKR MUTE switch - selects speakers OR phones/alt speakers
Hold the switch 2 seconds to display the TRIM level of the SPKR OUT audio on the digital display. Use the
-/+ keys to set the TRIM amount between 2 levels (0 and -12). The SPKR OUT TRIM display will turn itself
off after no adjustment has been made for 1 minute.
TALK Hold the switch down to talk to the CUE OUT/Phones jack and/or TALK MIC OUT jack using the remote
controller's built-in microphone. The TALK switch may have one of 3 functions depending on
configuration (see "Configuring the Remote Preamp"). Users may wish to connect the built-in Controller
mic to equipment such as a recording console listen-back inputs, or off-stage tech paging systems by
way of the TALK MIC OUT jack on the Base.
Hold the switch while also pressing the - key to latch TALK on [t.on]. TALK will remain latched until the
TALK switch is pressed again.
VU meters
CUE > VU Turn on to switch the VU meters from indicating Preamp levels to indicating Cue Mixer levels, post-EQ
and pre-CUE VOL control. Hold the CUE>VU switch 2 seconds to display the 0 VU setting on the digital
display. Use the -/+ keys to trim the 0 VU dB level from -3 to -20 in 1dB steps. The O VU display will turn
itself off after no adjustment has been made for 1 minute.
When CUE>VU is switched off, the 0 VU value indicates the signal level required to zero the meters,
relative to the maximum preamp output set by the GAIN Trim control. For example, if GAIN Trim
is set to
+18dBu and 0 VU is set to -14, a +4dBu sine wave will zero the meters. When CUE>VU is switched on
(meters follow the Cue Mixer levels), the 0 VU setting displays the dB level required to zero the meters
relative to the maximum output level of the SPKR OUT jacks with the CUE VOL knob set to 0. When SPKR
OUT is configured for Hi operating level the maximum output is +18dBu, when configured for Lo
operating level the maximum output is +6dBu (+4dBV). Therefore, setting 0 VU to -14 will zero the
meters at +4dBu for the Hi configuration and at -8dBu (-10dBV) for the Lo configuration when CUE>VU
is switched on.
Use the VU meters in conjunction with the PEAK warn and clip LEDs to get a complete picture of how the
sound source levels are fluctuating. VU's usually provide better indication than LED peak meters of the
audible signal volume, while PEAK (peak) LEDs monitor available headroom.
The meters are factory calibrated by sending a +4dBu signal to the DI input and setting the Preamp gain
to 0 dB. With GAIN Trim (maximum preamp output level) set to +18dBu and 0 VU set to -14, the trim-
pots on the back of the meter bridge are adjusted until the needles are zeroed. This procedure may be
reproduced any time there is concern the meters may have lost calibration.
