[. . . ] The bottom LED, EXT, has two possible states: · Solidly lit: When the bottom LED is solidly lit, all of the routed digital inputs are locked and all is right with the world. · Blinking regularly: When the bottom LED is blinking regularly, at least one (and maybe more than one) routed digital input is unlocked (i. e. , not synchronized to the external clock). Use the right-hand side of the clock menu page in the SETUP area to see which digital inputs are in fact unlocked. To check which digital inputs are routed, consult the routing menu pages discussed in Signal Flow Inside the H8000 on page 35. Page 56 the H8000 Operating Manual 2003 Eventide Inc. Manual Release 1. 1 The H8000 Operating Manual Sample Rate Conversion (SRC) In the absence of sample rate conversion (SRC), you need to make sure that any digital inputs are synchronized to the system sampling rate. If for whatever reason you cannot synchronize the AES/EBU or S/P DIF digital inputs to the system sampling rate, use sample rate conversion (SRC). The sample rate conversion pages are the two "bottom" menu pages under clock in the SETUP area. By turning SRC Mode on for the appropriate digital input, the H8000 will adjust the input sampling rate to match the system sampling rate. The sample rate before conversion is displayed in the Input SR x/x field. In this example, our internal clock rate is 48kHz. The SRCs are converting these 44. 1kHz inputs to 48kHz. The sample rate conversion algorithm is of a high quality and its presence is normally undetectable without the use of expensive test equipment. Nevertheless, the true audiophile will try to synchronize the input devices to the H8000 without using sample rate conversion in order to achieve the best possible results. Manual Release 1. 1 the H8000 Operating Manual 2003 Eventide Inc. Page 57 The H8000 Operating Manual Word Length (Bits) Input Word Length As mentioned in the introduction to this section, the H8000 assumes that the signals at the digital inputs are all 24-bit. Things work out regardless of the actual word length of the input signals because, for example, the 16 bits in a 16 bit signal correspond to the 16 "most significant" bits in a 24 bit signal. The 8 "least significant" bits are left "blank, " to be filled in by subsequent processing. If, however, the device sending the H8000 digital signals supports the protocol, you can see the word length at the inputs to the H8000. Go to the format menu page in the SETUP area. The fields on the left display the input word length (16 bits, 24 bits, and two unlocked signals in this case). If the input bits are unknown as in the case of an S/P DIF input, the field reads, quite logically, "unknown. " If a digital input is unlocked (not valid or not connected), the field will read "**. " Output Word Length The indicated output word length can be set on the right-hand side of the format menu page in the SETUP area. Your choices for output bits are: 16, 20, or 24. Unless a special "dithering" preset is in use, this setting will not indicate the actual output word length, but may be useful for external equipment. S/PDIF outputs do not support this word length indication. Page 58 the H8000 Operating Manual 2003 Eventide Inc. Manual Release 1. 1 The H8000 Operating Manual BYPASSING AND MUTING Sometimes you'll find it necessary to bypass the H8000 using the BYPASS key. A number of bypassing options exist in the LEVELS area. There are two "levels" of bypass, system and machine.
