[. . . ] Due to the outstanding SteadyClock technology of the HDSP MADI, we recommend not to pass the input signal via T-adapter, but to use the HDSP MADI's word clock output instead. Thanks to SteadyClock, the input signal will both be freed from jitter and - in case of loss or drop out ­ be held at the last valid frequency. 14. 3 General Operation The green `Lock' LED at the Expansion Board will light up as soon as a word clock signal is detected. Selecting `Word Clock' in the `Clock Mode' field will switch clock control over to the word clock signal. As soon as there is a valid signal at the BNC jack, 'AutoSync Ref' will display 'Word'. This message has the same meaning as the green `Lock' LED, but appears on the monitor, i. e. the user can check immediately whether a valid word clock signal is present and is currently being used. User's Guide Hammerfall DSP MADI © RME 19 15. TotalMix: Routing and Monitoring The Hammerfall DSP system includes a powerful digital real-time mixer. RME's unique TotalMix technology allows for nearly unlimited mixing and routing with all inputs and playback channels simultaneously. Here are some typical applications for TotalMix: · · · · · · setting up delay-free submixes (headphone mixes) unlimited routing of inputs and outputs (free utilisation, patchbay function) distributing signals to several outputs at a time simultaneous playback of different programs over only one stereo channel mixing of the input signal to the playback signal integration of external devices (effects etc). in real-time The block diagram of the TotalMix mixer of the HDSP MADI shows that the record signal always stays un-altered, but can be passed on as often as desired, even with different levels. The level meter of inputs and playback channels are connected pre-fader (due to the enormous routing capabilities). The level meters of the hardware's outputs are connected post-fader. User's Guide Hammerfall DSP MADI © RME 20 15. 1 Elements of the Surface The visible design of the TotalMix mixer is mainly determined by the architecture of the HDSP system: Upper row: hardware inputs. Per fader and routing window, any input channel can be routed and mixed to any hardware output (third row). · Middle row: playback channels (playback tracks of the software). Per fader and routing window, any playback channel can be routed and mixed to any hardware output (third row). Because they refer to the output of a subgroup, the level can only be attenuated here (in order to avoid overloads), routing is not possible. Every single channel has various elements: Input and playback channels each have a mute and solo button. Below each there is the panpot, realized as indicator bar (L/R) in order to save space. In the window below this, the present level is displayed in RMS or Peak, being updated about every half a second. The meter shows both peak values (zero attack, 1 sample is enough for displaying full scale) by means of a yellow line and mathematically correct RMS values by means of a green bar. The RMS display has a relatively slow time constant, so that it shows the average loudness quite well. The white area shows the channel name, the black area shows the current routing target. [. . . ] Warranty Each individual Hammerfall DSP undergoes comprehensive quality control and a complete test in a PC environment at RME before shipping. This may cause very slight signs of wear (if it looks like it was used one time before - it was). The usage of high grade components allows us to offer a full two year warranty. RME's replacement service within this period is handled by the retailer. [. . . ]
