'pages' where you can set the parameters using virtual knobs and sliders or by typing the values. Here is a brief overview of the various 'pages' that make up the TOTAL RECALL PC EDITOR. Each is explained in more detail in the next section. - Page 10 PRINT: Not a 'page' like those above, but an important function worth highlighting here. From the FILE menu, selecting PRINT provides a print-out of all the parameters of the TOTAL RECALL, together with the GLOBAL graph. View it before printing by selecting PRINT PREVIEW.
- Page 11 HIGH PASS/LOW PASS FILTERS (HPF & LPF): TOTAL RECALL is equipped with independent High-Pass filters for each of the Front & Rear channels, and a Low-Pass filter for the Subwoofer channel. For each filter there are 9 filter type/slope options:...
- Page 12 3-band full parametric equalization is provided on each of the channels. With this type of equalizer, frequency, gain and bandwidth are all variable. In addition, TOTAL RECALL allows you to select from a list of different EQ contours. Freq: The center frequency of each band can be set between 16Hz and 16,000Hz.
- Page 13 TOTAL RECALL is different. Firstly, TOTAL RECALL has 4 independent inputs feeding 5 independent output channels. But what really makes it different is that it's designed for use with full-range speaker systems that are either actively driven (i.e. the power amplifier stage is part of the speaker itself or forms a matched package that cannot be separated), or speaker systems that use passive crossovers after the power amplifier stage.
- Page 14 Parameter Menus & System Set-up What drives this Dynamic EQ feature is known in pro audio circles as a multiband compressor. It provides the ability to digitally split the full-range audio input signal on each of the Front and Rear Channels into low, mid and high bands and set some parameters that will cause the gain in the high and low bands to adjust automatically (that is, dynamically) in response to a change in the input level.
- Page 15 Dynamic EQ function. GAIN CONTROL SECTION: TOTAL RECALL has no analog input or output gain controls - output level adjustment is handled entirely in the digital domain. The input stage will accept a maximum unclipped input level of 2V rms.
- Page 16 Parameter Menus & System Set-up DYNAMIC GAIN CONTROL (LIMITER): Each channel has its own independent COMPRESSOR/LIMITER, allowing you to determine the amount of level gain (i.e. increase in volume) above a threshold point that you set. This helps maintain a more consistent listening level and both protects and extends the performance of your speakers.
- Page 17 You can keep the default filename or type one of your own. When you have done this, take TOTAL RECALL offline and then online again. This will force the system to do a network scan.
- Page 18 Hardware Programmer (optional item) An optional wired Programmer will be made available for setting the parameters of TOTAL RECALL as an alternative to using a PC. A 25-pin socket is provided on the unit ready to accept the Programmer. Please check with your dealer for...
- Page 19 Mounting TOTAL RECALL TOTAL RECALL has two fixing 'ears' at each side, allowing it to be firmly screwed to a suitable surface. Take care not to mount the unit where it may become wet or subject to damage from items placed in the trunk area. The unit may be mounted vertically or horizontally, but avoid mounting it upside-down (i.e.
- Page 20 The terminal marked REM (remote) accepts a +12V switched input from the source unit (Cassette or CD player). When the source unit is switched on, a pulse is sent down this line. TOTAL RECALL senses this pulse and switches itself on.
- Page 21 Before reconnecting power to the circuit, double check all connections are correct and secure. On turning on the CD or Tape player, the power-on LED next to the power input terminal block of TOTAL RECALL should light to show the unit is receiving power.
- Page 22 RECALL (the power amplifier or the speaker itself). Check the amplifier gain controls and any input switching options (such as built-in crossover networks). If the fault moves to the other speaker then your TOTAL RECALL may be faulty- leave it installed in your system and return to your dealer so that they can check it.
