3.2 70/100V Switch
When this switch is in the “OFF” position, the amplifier is configured to drive low
impedance speakers, (4 Ohms ,minimum) The Hi-Z switch will switch in the built-in
output transformer allowing the unit to drive 70V or 100V speaker systems directly
when connected to the appropriate output terminals. As an added feature when
driving the high impedance speakers, the system automatically switches in a 70Hz
high pass filter.
3.3 Remote Control Capability
Remote volume control can be implemented using a CSR-V controller connected
via an Ethernet cable to the RJ45 connector on the back panel. For the CSA 2300Z,
there are two connectors, one for each amplifier output.
Additional features are remotely accessible through the RJ45 port using serial
control. (For the CSA 2300Z, where there are two RJ45 connectors, the serial control
feature is accessible via the Channel 1 connector only.)
Please see Appendix B for more details regarding remote operation using RS232.
