When the ON button is depressed, Channel 1 output becomes "Left"
and Channel  output becomes "Right". The Channel 1 gain control
adjusts the mono signal level applied to both the Left and Right outputs.
The Channel  gain control adjusts the stereo image width.
Direct inputs DI1 and DI are controlled by gain controls for channels 
and 8, respectively. The gain range for the direct inputs is from 4
dB to +44 dB.
RESET clears the peak-hold indicators on all channels. NOTE: It is normal
for the Peak-Hold indicators to activate when phantom power is ap-
plied, when AC power is applied, or when a new setting is made on the
PEAK REFERENCE selector. Simply depress RESET to clear the indicators.
This sets the level at which the Peak-Hold Indicators
changes the operating level indication  to 10 dBV operation when the
10 dBV position is selected.
The green power LED indicates that the unit is ON and running.
The Peak-Hold level indicators can operate in two modes. As supplied,
only the OL and PK indicators will hold (after they are activated) until
RESET is depressed. An optional mode is available which causes the 
and  indicators to also hold until RESET is depressed. This mode can be
helpful in live sound and recording applications where the PRECISION 8i
is remotely located from the device(s) to which it is connected. Jumpers
inside the unit select this optional mode. If you wish to configure the
unit for this mode, proceed as follows:
Dangerous voltage exists inside the enclosure of this product. This op-
eration should only be performed by qualified personnel. NEVER open
the product enclosure while the AC power cord is attached!
• Disconnect AC power cord.
• Remove the twelve screws securing the top cover to the enclosure.
Remove the cover.
• Locate the eight upright printed circuit boards along the front panel.
• Select level indicator mode by setting jumpers (J) as shown here.
Replace cover and secure with twelve screws. Make sure no tools, loose
hardware, debris, etc. remain in the unit prior to attaching the cover.
