PRECISION 8i

OPERATION MANUAL

activates at peak level minus 6 dB. Generally, the PEAK REFERENCE selector is set for the maximum level you want to present to your mixing console, recorder, etc. Depress RESET 10 to clear PK.

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.

Note that the overload level of the PRECISION 8i is +31dBu at the output. This level exceeds the input capability of some devices (check manufacturer’s specifications). In other words, it may be possible to cause overload distortion in the connected device even though the PRECISION 8i level indicator does not show a red light. We can provide accessory Output Attenuators in applications where this is necessary. Please consult the factory for assistance.

5Signal Present indicator. The SIG indicator activates at approximately -24 dBu.

6Operating level indicator. The +4 indicator activates when the output level reaches

+4 dBu normal operating level. When the PEAK REFERENCE selector 9 is set to the -10 dBV position, the operating level indicator activates at -10 dBV output level.

7Mid-Side mode selector. When the ON button is depressed, Channel 1 output becomes “Left”and Channel 2 output becomes “Right”. The Channel 1 gain control adjusts the mono signal level applied to both the Left and Right outputs. The Channel 2 gain control adjusts the stereo image width.

8Gain control. This control adjusts the preamp gain over the range of 16 dB to 64 dB.
