User manual M-AUDIO CO3

[. . . ] This pushbutton selects one of the three input jacks to be the source of incoming digital audio. Repeatedly pressing this button will cycle through the three available selections. When lit, the LED indicates the input data is recognizable and has valid format. When not lit, the LED indicates invalid or no data at the selected input. [. . . ] Regardless of what the input SCMS bits are, the SCMS output bits are forced to the "no copy protection" setting. The SCMS bits from the input are passed through untouched to the outputs. Regardless of what the input SCMS bits are, the SCMS output bits are forced to the "original copy" setting. Regardless of what the input SCMS bits are, the SCMS output bits are forced to the "1st generation copy" setting. Installation and Setup Your CO3 box should contain this manual, the CO3, and its "wall-wart" DC power adapter. With the CO3's power button in the outward "off" position, plug the appropriate end of the power adapter into the CO3's power jack, and the other end into a live wall socket or power strip. NOTE: All CO3 inputs and outputs are transformer isolated or optically isolated except for the coaxial S/PDIF Input (the RCA input jack). This allows devices to be plugged into and unplugged from the CO3 while power is on, except for the coaxial S/PDIF Input jack -- CO3 power should be turned off before connecting to or disconnecting from the coaxial S/PDIF Input jack. Connect one end of the proper cable to the output of your digital audio "source" and plug the other end into the matching CO3 input jack. Then connect one end of another appropriate cable between the desired CO3 output jack and the input jack of some receiving digital audio device(s). Turn on your digital audio source device, then turn on the CO3 by pressing 4 in the "Power" button. The CO3 will always power on with TOSlink Optical S/PDIF as the source selection, and "Pass-Thru" selected as the SCMS setting. From the front panel of the CO3, select the input source setting that matches the format of your input source. Optionally, set the SCMS mode to its desired setting (more specific information about this is coming later in the manual). NOTE: Although it is acceptable to change the various settings of the CO3 while power is turned on, you might hear small bursts of noise while switching. This is normal as it takes a small amount of time for external devices to "lock on" to a digital data stream after the switching takes place. Now, depending on what input you are using, and what the SCMS setting is, the CO3 will automatically convert the input stream to the output stream(s). Making sure the volume control on your receiving digital device is set low, power up the device. Depending on the product, the receiving device may require some configuration in order to accept data at its digital input port. Advanced Information Inside the CO3, there are many different conversions to be made depending on the front panel settings and the characteristics of the actual incoming digital data stream. This section describes the various actions taken by the CO3 in various circumstances. The various CO3 modes are also summarized in the table at the end of the manual. SCMS Modes SCMS or "copy protection" bits are present in S/PDIF data streams (on the CO3's RCA and TOSlink connectors) only. The AES/EBU specification does not define an SCMS capability and therefore the digital streams at the CO3's AES/EBU jacks carry no SCMS information. When converting from S/PDIF to AES/EBU, the SCMS bits must be removed from the digital stream because there is no place for them in the AES/EBU output stream. [. . . ] In the event that MIDIMAN determines that the product requires repair because of user misuse or regular wear, it will assess a fair repair or replacement fee. The customer will have the option to pay this fee and have the unit repaired and returned, or not pay this fee and have the unit returned unrepaired. The remedy for breach of this limited warranty shall not include any other damages. MIDIMAN will not be liable for consequential, special, indirect, or similar damages or claims including loss of profit or any other commercial damage, even if its agents have been advised of the possibility of such damages, and in no event will MIDIMAN's liability for any damages to the purchaser or any other person exceed the price paid for the product, regardless of any form of the claim.
