Information from
the Signal Level
Meters
When configuring the EF1210, it is very important to know which signal level meter
to look at. On the front panel, there are two signal level meters — the I
NPUT
signal
level meter and the R
EMOTE
signal level meter. When configuring the input channels
(microphones 1-8), use the I
NPUT
signal level meter. When configuring the reference
inputs (AEC A and AEC B), use the R
EMOTE
signal level meter.
Take note that unlike a microphone mixer, the signal level meters do not show a total
output signal, meaning the EF1210 does not add up, for example, all eight input sig-
nal levels and show them on the I
NPUT
signal level meter. Instead, what is shown on
the signal level meters is the individual signal level of the input channel or reference.
To display the desired input or reference signal when the EF1210 is in normal opera-
tion (not setup mode), press the appropriate S
ELECT
button. Push the R
EF
S
ELECT
button to cycle through the two reference inputs. Push the I
NPUT
S
ELECT
button to
cycle through the eight input channels. Use the LEDs on the right side of the front
panel as an indicator of which level is displayed on the LED meter. The input chan-
nels are indicated by the LEDs labeled C
HANNELS
1-8. Reference inputs are indicated
by the AEC A or AEC B LED.
If you do not see activity on the signal level meter while a talker is talking, do not
immediately assume that the level needs to be turned up. First check to make sure
you are looking at the correct input or reference on the signal level meter.
