4. Brief Description and Characteristics

Hammerfall design: 0% (zero!) CPU load, even using all 52 ASIO channels
All settings can be changed in real-time
Enhanced mixed mode: ADATs In, SPDIF In, and all outputs can be used simultaneously
8 available buffer sizes/latencies: 1.5 / 3 / 6 / 12 / 23 / 46 / 93 / 186 ms
Sample Split technology for 12 channel, 96 kHz/24-bit record/playback via ADAT optical
Slave and master clock modes
Automatic and intelligent master/slave clock control
Unsurpassed Bitclock PLL (audio synchronization) in ADAT mode
Word clock input and output
ADAT Sync in (9-pin D-type) for sample-accurate transfer
Zero Latency Monitoring: Hardware bypass per track, controlled by Punch in/out
Enhanced ZLM for latency-free submixes and perfect ASIO Direct Monitoring
SyncAlign guarantees sample aligned and never swapping channels
SyncCheck tests and reports the synchronization status of input signals
2 x MIDI I/O, 32 channels high-speed MIDI
1 x Analog Line/headphone output, separate output for independent submix
DIGICheck DSP: Level meter in hardware, peak- and RMS calculation
TotalMix: 1456 channel mixer with 40 bit internal resolution
