Precision 8 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 8.
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 8 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 8, the shipping carton should also include:
Ÿ An AC power cord
Ÿ A warranty registration card
Ÿ A “Caution” sheet
Ÿ 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 8 enclosure.
Mounting
The PRECISION 8 is designed for conventional rack mounting, or stand-alone
mounting by use of the adhesive rubber feet supplied. Avoid locating the unit next to
