[. . . ] THETA DIGITAL C O R P O R A T I O N Dreadnaught Owner's Manual Rev 102c PREFACE CONGRATULATIONS You have just acquired the most advanced and versatile component for the amplification of audio ever to have been developed. IMPORTANT Save all packaging in a dry place away from fire hazards. Your Dreadnaught is a precision electronic instrument and should be properly packaged any time shipment is made. In the unlikely event that you have to return your Dreadnaught to the factory for service, or if you send it to us for updating, the original packaging will best protect the unit from shipping damage. In order to achieve the fullest flexibility and enjoyment from your Dreadnaught, we at Theta recommend that you read this manual in full before connecting the unit to your audio/video system. [. . . ] Damage to the Dreadnaught caused by improper operation, wiring and/or ventilation will not be covered under warranty and Theta will not be liable for any consequential damage or loss. When first turning on the rear panel power switch, the red STANDBY LED on the front panel will illuminate, indicating that all channels are in standby mode. When in standby, the signal is muted and the output bias of each channel is reduced to approximately 10 percent. The SURROUND LED on the front panel will illuminate green, indicating that all channels, regardless of which buss they are assigned to, will come on when the amplifier is taken out of standby. When in standby, the front panel STANDBY LED will be red and when out of standby, this same LED will be green. The SURROUND button activates/deactivates the channel(s) that been assigned to the surround buss via their rear panel switch. When the surround buss is active, the SURROUND LED on the front panel will illuminate green. When the surround buss is inactive, the front panel SURROUND LED will be off. The surround buss may be turned on or off regardless of whether the unit is in standby or operate. Any number of channels can be selected to operate on either of the STEREO or SURROUND busses. When the Dreadnaught has more than two channels installed in it, it is recommended that the front left and right channels be set to STEREO and all remaining channels be set to SURROUND, via the rear panel STEREO/SURROUND switch. In the STEREO mode (front panel SURROUND LED off), any channels set to the STEREO buss will operate. In the SURROUND mode (front panel SURROUND LED illuminates green), all channels will operate. Single and Two channel Modules The Dreadnaught can be loaded with any combination of channels. Each module can be set to operate individually on the stereo or surround buss. Note: The speaker output polarity on the single channel module is opposite of that on the two channel module. The maximum spade lug thickness for the two channel module is 1/16" Remote Triggers When the rear panel STANDBY TRIGGER jack receives a 5-12 VDC pulse, the Dreadnaught will change its state from either standby to operate, or operate to standby, depending on what the current state is. When the rear panel SURROUND TRIGGER jack receives a 5-12 VDC pulse, the Dreadnaught's surround buss will change from its current status, either on or off. Use a 1/8" (3. 5mm) mono plug for these jacks. RS232 RS232 is an option in the Dreadnaught. It can be installed at any time either at the factory or an authorized Theta dealer. All functions of the Dreadnaught can be controlled and monitored via RS232, using either the RJ45 or DB9 connector. As long as the rear panel power switch in turned on, the RS232 circuitry is always active, thus allowing the Dreadnaught to be taken out of STANDBY via RS232. 8 Appendix A Troubleshooting Guide If the Dreadnaught should function abnormally during operation, please review the items in the following checklist. Please be sure to thoroughly check all other connected components such as speakers, preamplifiers, as well as cables. [. . . ] 17 5/8" W x 8 7/16" H x 23 1/2" D (448 x 214 x 597 mm) 100 Lbs.
