3 Types of pro tools systems
|
M-Powered LE and HD
|
|
Why is HD the best
|
higher track counts, voicing and sample rates; more software features; more I/O's, DSP chips, HW based power, stability, lower latency
|
|
PT HD sample rat and bit depth
|
up to 192khz and 24 bit
|
|
Core components of a PT HD system
|
Computer, PT software, Hard Drives, PCI/PCIe Core Cards (HD core/accel core), audio interface (192 I/O, 96 I/O)
|
|
optional components
|
Hd process card (predecessor of the HD Accel card) and the Accel card
|
|
additional audio interfaces
|
192 I/O, 192 digital I/O, 96 I/O, 96i I/O
|
|
other system options
|
digi pre, sync I/O, midi I/O (includes support for midi time stamping)
|
|
how many DSP chips are on a PCI or PCIe card
|
9
|
|
what is TDM?
|
time division multiplexing. instead of a 1 way data stream, TDM communicates with multiple chips simultaniously
|
|
TDM II provides___________time slots at either 44.1 or 48k
|
512
|
|
where are the hardware routing controls?
|
setup>hardware
|
|
The HD interface provides 16 ins and 16 outs connected to the card in the computer with a _______
|
16 channel digilink cable
|
|
the connections are displayed in th HW setup dialog box as______
|
digilink channel pairs
|
|
HD interfaces support _______ or, multiple destinations for outputs
|
output mirroring
|
|
to choose multiple outs in the HW setup, press
|
Control while clicking additional outs
|
|
how many bits is the mixer
|
48 via a dithered mixer plugin
|
|
can it use multiple DSP chips?
|
yes
|
|
it uses how many chips?
|
2 24bit TDM time slots per connection
|
|
the mixer shifts the original 24 bit word to the middle of a ___bit register
|
56
|
|
This allows ample
|
headroom and footroom to sum 128 full-code tracks with all faders at +12 with out clipping on the input or down to -90 while still contributing 24bits to the mix preserving low level details
|
|
do master faders use DSP?
|
no
