carrier-freq
uency
4.8kHz
On the basic version of the device, channels 0 to 3 are fitted with
4.8kHz carrier-frequency amplifiers (600Hz for Spider8-30)and
channels 4 to 7 are closed off with blank plates.
With Spider8, channels 4 to 7 can either be fitted with 4.8kHz
carrier-frequency amplifiers (SR55) or DC amplifiers (SR01); with
Spider8-30 the options are 600Hz amplifiers (SR30) or DC
amplifiers (SR01). The appropriate transducers are connected to
these modules (see also Chapter D-3).

Chapter C ”Commissioning” tells you how you can later fit channels
4 to 7 with modules.
