5 - Using the Settings Panel INFORMATION page 1 Status display area This shows the current status of the unit. Item displayed Meaning Software Version This is the software version. Firmware version This is the firmware version used by the connected unit. Device This is the name of the connected unit. (No Device is shown when no device is connected.) Clock Source This shows the name of the currently selected clock source. Sample Rate This shows the current sampling frequency. Clock Source Status This shows the sampling clock status. Good: There are no problems. Unlocked (or No Signal): There is no valid signal or it is disconnected. Phase Error: This unit and the device that is optically connected are not synchronized. Sample Rate Mismatch: This unit and the device that is optically connected have different sample rates. OPTICAL A Input Status This shows the OPTICAL input status. Good: There are no problems. Unlocked (or No Signal): There is no valid signal or it is disconnected. Phase Error: OPTICAL B Input Status (SERIES 208i only) This unit and the device that is optically connected are not synchronized. Sample Rate Mismatch: This unit and the device that is optically connected have different sample rates. * Note about the sample rate of this unit ii Win: Set the same sample rate for both the Playback and Recording tabs of the Sound Properties in Control Panel screen. ii Mac: Set the sample rate in the Audio Devices window of Audio MIDI Setup. 20 TASCAM SERIES 102i / SERIES 208i NOTE ii When the unit and the computer are not connected, "No Device" is shown for the "Firmware Version" and "Device" items. ii When the 2 Sample Clock Source item is set to "Internal", the Clock Source Status item will appear dimmed as 2 Sample Clock Source Use this to set the sampling clock source. Option INTERNAL OPTICAL A OPTICAL B (SERIES 208i only) WORD (SERIES 208i only) Meaning The unit's built-in clock is always used. The clock signal input through the OPTICAL IN (S/MUX) connector is used. If the connected device is a TASCAM device and 3 Rate setting is "Auto - TASCAM Device", the input clock signal will be automatically identified and set. The clock signal input through the WORD IN connector is used. NOTE ii When set to OPTICAL A, OPTICAL B or WORD, if no signal is input through the corresponding connector or synchronization becomes impossible, the status will appear in the Clock Source Status item and this unit's STANDBY indicator will blink. ii When connecting multiple digital devices to the SERIES 208i, synchronize them to a system word clock and input word clock supplied by the master clock device to the SERIES 208i. ii After changing the clock source, proper continuation of playback/recording might not be possible, so you should restart the playback/recording software that you are using. 3 Rate items Use these to set the connected OPTICAL (S/MUX) sample rates. If the connected device is also a TASCAM product, select "Auto - TASCAM Device" to set this automatically. Options: A uto - TASCAM Device, Manual - 44.1kHz/48kHz, Manual - 88.2kHz/96kHz, Manual - 176.4kHz/192kHz 4 Buffer Size (Windows only) The Windows driver for the unit stores the audio signals transferred to and from the computer temporarily in a buffer. This buffer size can be adjusted. Smaller buffer sizes result in less audio signal delay (latency), but require high-speed processing by the computer. If the processing cannot keep up, for example, due to other system operations, clicking and popping noises might occur and the audio signal might even drop out. Increasing the buffer size will stabilize operation and suppress negative effects on audio signals, but the delay in audio signals sent to the computer will increase. You can use the slider on the panel to adjust the buffer size, according to the use conditions. Use the slider to select fixed values that increase from left to right. Options: 4 Samples, 8 Samples, 16 Samples, 24 Samples, 32 Samples, 64 Samples, 128 Samples, 256 Samples, 512 Samples, 1024 Samples, 2048 Samples
