PRECISION 8i
OPERATION MANUAL
15
Drum kits: use an M-S pair for drum overhead micing.
Vocal and instrumental ensembles: use M-S to give realistic perspective to backup
vocals or instrumental groups.
Individual instruments or vocals: try M-S on acoustic guitar and in situations where
you wish to capture room ambience.
Broadcast/film sound: use M-S to capture audience noise or background ambience.
M-S can also be used in TV and film work to match the sonic image width to the
visual image width.
Optional Level Indicator Modes
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 -3 and -6 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:
