Congratulations!
You have just purchased one of the finest solid state power amplifiers made. Whether in mono, stereo or in multi channel usage, the CAD 500 MB and the CAD 200 are audiophile quality power amplifiers. In addition to awesome power delivery, the CAD 500 MB and the CAD 200 power amplifiers deliver flawless reproduction of musical detail.
Cary Audio Design solid state power amplifier features include:
•Remote trigger (works with + 4.2 to + 32 Volts DC)
•Short circuit protection,
•Thermal Protection circuits
•DC offset protection
•Matched 50 MHz multiple emitter output transistors
•Soft start circuit prevents “Brown outs” when amplifier is turned on
•Pure Balanced FET input section in the CAD 500 MB mono balanced power amplifier
The Cary Audio Design CAD 500 MB and CAD 200 power amplifiers have three separate protection circuits to prevent damage to your speaker and the power amplifier.
•AC Fuse - Fused with a 3.5A/7.5A for 240V and a 7.5A/15A for 120V.
•Thermal protection - if a channel overheats its output is disconnected until it cools down to a safe operating temperature.
•DC offset sensor - If an amplifier malfunction or signal source malfunction occurs, the potential exists for providing DC voltage to the loudspeaker. If this happens, the channel will automatically shut down. No damage can occur.
In building the CAD 500 MB and CAD 200 power amplifiers, significant effort has been focused on building an amplifier that delivers outstanding mechanical performance, is easy to use, and has sonic properties that will delight the most demanding audiophile customer. Thank you for choosing Cary Audio Design and we hope you enjoy your new power amplifier.
*Short circuit protection activates if load impedance is about 1.6 ohms or less. Constant tripping of short circuit can degrade output transistors. To reset protection, turn the amplifier off, wait 10 seconds, then turn the amplifier on.
