Please refer to the front panel view on page 4.

After connection to the Mains supply, switch the Caspian 5-Channel Power Amplifier ON at the rear panel. It will enter STANDBY and the STANDBY LIGHT (2) glows RED. Press either of the MODE buttons (1 or 9), after a couple of seconds, the amplifier will set it self in AUTO mode and the AUTO LIGHT (8) will glow GREEN and the STANDBY LIGHT (2) will extinguish. Your Caspian 5-Channel A/V Power amplifier is now ready for use.

To set the amplifier back into standby, press either of the MODE buttons (1 or 9), and the AUTO LIGHT will extinguish and the STANDBY LIGHT (2) glows RED.

Thanks to its advance circuit design and 1 kVA power transformer, the Caspian 5-Channel Power amplifier is capable of audiophile sound quality with excellent transient power to compliment both ‘pure audio’ and audio/visual sound tracks. Your Caspian 5-Channel power amplifier is a high power, high current amplifier with very low distortion.

Most of the time, even with the most demanding material, it will not current limit and the distortion will remain ultra low. However when using low impedance loudspeakers at very high volume levels or when the surround sound processor output is set too high, the amplifier may occasionally current limit and its output distortion begin to increase. The control circuit of your 5-Channel Power Amplifier will automatically detect this and on the front panel display the corresponding channels’ Overload Indicator (3, 4, 5, 6 or 7) will glow RED. You should first check the output of level of your surround sound processor and if it is set too high Trim it lower. Secondly lower the Master Volume and if applicable consider Multi-Amping your loudspeakers.

IMPORTANT NOTE: The current Overload Indicators will only illuminate if the amplifier is driven continuously at or past its maximum current capacity. These indicate overload of the power supply just before the onset of audible distortion. These Indicators in virtually all imaginable listening situations will rarely illuminate

The control circuit indicates a fault when one or more of the Overload Indicators glow continuously RED without any input signal. You should switch the amplifier immediately off and contact your ROKSAN Authorized Retailer.

Multi-Amping The Loudspeakers

Operation

If the Loudspeakers utilise more than one drive unit with individual input terminals, for example a Tweeter and a Woofer, then the loudspeaker performance will benefit from Bi-Amping. Dedicating one amplifier to the Tweeter and another to the Woofer, isolates them from each other hence reducing distortion and increasing reserved power. Speakers work far better with most amplifiers when Multi-Amped than using one yet more powerful amplifier. Note: Bi-Wiring reduces the impedance seen by the Woofer and the Tweeter and is a first step towards Bi-Amping.
