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: ADAT 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

• DIGICheck DSP: Level meter in hardware, peak- and RMS calculation

• TotalMix: 1352 channel mixer with 40 bit internal resolution
