OVERVIEW

1.2 Front Panel

Class A Mic Pre. Each channel of your DigiMax FS contains a Class A discrete differential input amplifier, providing ultra low noise and wide gain control allowing the DigiMax FS user to boost desirable signal without increasing unwanted background noise.

Neutrik Combo Connectors. Each channel of the DigiMax FS has a Mic/Line connector using the Neutrik Combo connector. This revolutionary style connector enables you to use either ¼” phone or XLR connectors in the same female input. The first two channels of the FIREPOD are ¼” instrument and microphone XLR inputs. The line level inputs for these two channels are on the back panel of the DigiMax FS via return 1 & 2.

48V Phantom Power. Channels one through four and five through eight of the DigiMax FS have a 48V Phantom power available in groups. When the Phantom power switch is engaged, power is supplied at a constant rate to that group of preamps, assuring optimum performance of your condenser microphone(s). These switches are located on the far left of the front panel.

Sample Rate Selector. The DigiMax FS has a switch on the front panel for sample rate selection (44.1k, 48k, 88.2k, and 96k.)

EXT Clock. The external clock switch allows the DigiMax FS to choose an external source for clocking. To switch between ADAT and BNC sync, simply engage the switch again. The switch will light RED for ADAT sync and BLUE for BNC sync. When in either mode, the DigiMax FS will automatically recognize which sampling rate is required for optimum synchronization.
