PRECISION 8i
OPERATION MANUAL
7
About the Level and Peak-Hold Indicators:
1.
SIG
indicates that a signal is present on the channel. It illuminates when the signal
level exceeds -24dBu.
2.
+4
illuminates when the output signal reaches normal operating level of +4 dBu.
3.
OL
illuminates when the signal level exceeds +26 dBu, which is 5 dB below the
overload point for the
Precision 8i
.
4. The PEAK-HOLD indicators (
PK
,
-3
,
-6
) activate when the output signal level exceeds
the level set on the
PEAK REFERENCE
switch.
5.
For example
: With
PEAK REFERENCE
set to
+26
the
PK
indicator illuminates (and
stays on) at +26dBu, the
-3
indicator illuminates at +23 dBu and the
-6
indicator
illuminates at +20 dBu.
6.
NOTE:
Only the
OL
light indicates impending preamp overload. The red
PK
light
simply indicates that the signal has exceeded the level selected on the
PEAK
REFERENCE
switch.
7. Push the
RESET
button to reset the PEAK-HOLD indicators for all channels. (It is
normal for power-on transients and phantom power transients to activate the PEAK-
HOLD indicators. Simply depress
RESET
to clear the indicators.)
INSTALLATION
Unpacking and Inspection
We recommend that you inspect your
PRECISION 8i
upon unpacking it from the
factory shipping carton. In the unlikely event that the unit exhibits any physical damage,
DO NOT connect it to the AC mains power, but contact your dealer immediately.
In addition to the
PRECISION 8i
, the shipping carton should also include:
An International Power Supply Module (PSU-P8i)
An AC power cord
A warranty registration card
A “Caution” sheet
This Operation Manual
We recommend that you keep the shipping carton and foam supports in the event that
the unit must be shipped at some time in the future. DO NOT package the unit in
“packing peanuts” or similar material as it will settle during shipping and damage will
likely occur. If original packing materials cannot be located, wrap the unit with a liberal
amount of plastic “bubble wrap” material extending at least 2” beyond the extremities of
the
PRECISION 8i
enclosure.
