MANUAL OPERATION

Press the MANUAL Button (1). The MANUAL Indicator Light will glow RED. The amplifier will now be operational. To return the amplifier to Standby, press MANUAL Button again. The MANUAL Indicator Light will glow GREEN.

AUTOMATIC OPERATION

Press the AUTO Button (4). The AUTO Indicator Light will glow RED and the amplifier will be operational. To go to Auto Standby, press AUTO Button again. The AUTO Indicator Light will glow GREEN.

When the amplifier is in Auto Standby, it will switch itself ON whenever an audio signal is applied to the inputs. If the amplifier does not receive a signal for approximately five minutes, it will switch itself back to Auto Standby. With this facility the Caspian Power Amplifier is ideal for Multi-amping or in any application, (e.g. multi-room), where the amplifier is required to switch ON and OFF with the rest of the system with no loss of functionality.

KNOW YOUR CASPIAN

•When you first power up from the Mains Switch on the rear panel, the amplifier runs a self-test and then enters Standby and the MANUAL Indicator glows GREEN.

•During Standby, the power stage of the amplifier shuts down to reduce power consumption and heat.

•The AUTO and MANUAL Buttons toggle each other ON and OFF. In Auto Mode, pressing the MANUAL Button will set the amplifier to Manual Standby, and vice versa.

•If the amplifier detects an external fault, such as short-circuit on the loudspeaker leads, the amplifier will go to Standby. You can only bring the amplifier out of Standby when the fault is cured.

•If the amplifier overheats through overload or lack of ventilation, the Caspian will revert to Standby. When it has cooled down you will be able to bring it out of Standby.

In the unlikely event of an internal fault such as a power supply fault, the amplifier will go to permanent Standby.

If you suspect that your ROKSAN Caspian Power Amplifier is not operating properly, you should check all the connections carefully. Pay particular attention to speaker phasing and channel connections. Phono plugs should be fully inserted- a frequent cause of problems is that Phono plug surrounds do not make proper contact. Below are some commonly encountered problems with suggestions for possible cure. The list is not exhaustive: If you have any unresolved problems, please consult your appointed ROKSAN dealer or distributor.
