[. . . ] G U A R A N T E E D F O R L I F E 1 MANUAL SAM TM 24 BIT S / P D I F / A D AT MIXER & FORMAT CONVERTER Table of Contents FCC Class B and CE Compliance . 15 FCC Class B and CE Compliance WARNING: This equipment has been tested and found to comply with the limits for a CLASS B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions contained in this manual, may cause harmful interference to radio and television communications. [. . . ] This high-speed optical signal is capable of transferring 8 channels of 24-bit audio data simultaneously. The sample rate of the ADAT Out data will be synchronized with the incoming S/PDIF In data. S/PDIF In: This connector mates with a (male) RCA coaxial cable carrying S/PDIF data into the SAM. This signal is capable of transferring two-channel "left/right stereo" data of up to 24 bits. S/PDIF Out: This connector mates with a (male) RCA coaxial cable carrying S/PDIF data out of the SAM. This signal is capable of transferring two-channel "left/right stereo" data of up to 24 bits. The sample rate of the S/PDIF Out data will be synchronized with the incoming ADAT In data. 7 Installation and Typical Setup Your SAM box should contain this user manual, a power adapter, Midiman warranty card and the SAM unit itself. Remove the SAM and power adapter from the box. Verify that the SAM and any other devices you plan to connect to it are turned off (devices with ADAT Optical connections may remain on but their volumes should be turned down or off). Now, connect your S/PDIF and ADAT Optical cables to the SAM. Plug one end of the power adapter into the SAM's power jack and plug the other end of the power adapter into a live wall socket or power strip -- this will power up the SAM unit. With all volume controls of non-SAM equipment turned down or off, power up each of these devices. Note: The SAM has no Power On/Off switch. However, the SAM may be safely left on continuously, 24 hours a day. After hours of operation, it is normal for the SAM metal chassis to become slightly warm to touch. A typical configuration in which a SAM would be used includes a SAM, an ADAT, a computer-based S/PDIF digital I/O card or DAT recorder with S/PDIF I/O and an amplifier/sound system for monitoring purposes. Such an example configuration could be setup as follows: 1. ) the Optical Out of the ADAT connects to the Optical In of the SAM, 2. ) the S/PDIF Out of the SAM connects to the S/PDIF In of the digital audio card and DAT, 3. ) an analog audio out from the computer or DAT may connect to an amplifier/sound system. 2 ADAT Computer Sound System sam 8 or DAT Additionally, the signal path might be reversed in the same basic configuration and both setups may exist simultaneously. In this case: 1. ) the S/PDIF Out of the digital audio card or DAT connects to the S/PDIF In of the SAM; 2. ) the Optical Out of the SAM connects to the Optical In of the ADAT. 3 ADAT Sound System sam Computer DAT 9 Operating Modes Overview The SAM has six different operational modes which are selectable via the Mode button. Five of these modes translate ADAT Optical signals to the S/PDIF format and the sixth mode translates S/PDIF signals to the ADAT Optical format. Mix Mode: When SAM is first turned on it will be in Mix mode, one of the ADAT-to-S/PDIF modes. [. . . ] Check your source signal levels and cables. Either the source signal is too weak or there is no digital target plugged into the SAM's output. The front panel Input Level CLIP LED is always lit (or frequently lit). Check your source signal levels and cables. [. . . ]
