PRECISION 8i

OPERATION MANUAL

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 -3indicator illuminates at +23 dBu and the -6indicator 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.
