Congratulations with your new Preamplifier/Processor SPACE PR350 B. The SPACE PR350 B contains advanced technology for an outstanding range of features and sound performance. We are sure that the PR350 B will give you long lasting pleasure. To give you full benefit from this advanced product, please read this manual carefully before you proceed.
Following formats are used: Cursive text indicates display readout, e.g.: CONFIG Key type is indicated with “”, e.g.: “ENTER” key. Stereo speakers: “L” : left speaker “R” : right speaker Surround speakers: “C” : center speaker placed in front of the listening position “SL” : surround left speaker placed rear left of the listening position “SR” : surround right speaker placed rear right of the listening position Extended surround speakers: “SC” : surround center speaker placed back of the listening position.
0. Installation Place the amplifier on a hard and flat surface. The ventilation holes should not be covered. There has to be at least 5 cm (2 inches) free air on top of the amplifier. To ensure long and trouble free operation we recommend: - Do not expose the amplifier to direct sunlight. - Do not place the amplifier in warm or dusty environments. Caution: Because of risk of fire or electric shock, do not expose the amplifier to rain or moisture.
a CD player or DVD player to one of the available digital inputs in the PR350 B and use the balanced 24bit D/A conversion for L and R channels, built into the PR350 B. The Space PR350 B is also optimised for D/A conversion of the 24bit/96kHz stereo DVD disc’s with music. 2. Volume controls The master volume level is set by rotating the volume knob on the front panel or by using the “VOL ⇑” or VOL ⇓” key on the remote control.
3. Zone 2 With zone 2 it is possible to redirect the sound to other audio systems, e.g. placed in kitchen or bedrooms. The zone 2 has separate volume control and input selector. Adjustments for zone 2 are achieved by holding down the same input knob as currently selected. E.g. when DVD input is selected, hold down the “DVD” knob on remote or frontpanel, approx. 1 sec. Then the ZONE2 indicator becomes active.
A sound wave travels at approx. 340 meter/sec., which is equivalent to: 1 foot in 1 millisecond 1 meter in 3 milliseconds or Following example demonstrate how to calculate the delay setting for SL, SR, SC and C: From the listening position to each speaker, we measure following distances: Listening position <-> Left speaker: Listening position <-> Right speaker: Listening position <-> Center speaker: Listening position <-> Left surround speaker: Listening position <-> Right surr.
The user may still prefer to change delays during playback of a movie, based on subjective preference in a specific movie. Hence the delay can also be set “on the fly”. The intermediate delay settings will return to the default settings stored in the memory banks when the PR350 B is set into standby or powered off. 5. Surround Modes The actual surround mode of the PR350 B is always indicated in the display: Possible input types: analogue input, PCM or Dolby Digital 2.
And the transmission bit rate of the received bitstream: 32k : 32 kbit/sec. . . 448k : 448 kbit/sec. 768k : 768 kbit/sec. (only DTS) 1411k : 1411 kbit/sec. (only DTS) 1532k : 1532 kbit/sec. (only DTS) If only two audio channels are active in the received Dolby Digital bitstream (2/0), the input is assumed to be Dolby ProLogic II, if indicated in the bitstream, otherwise as two channel stereo.
DTS 6.1 Compatible: This DTS mode is actually identical to DTS ES 6.1 Matrix as described above, but by enabling this mode the user choose always to activate the matrix process on the SL and SR to generate the SC channel. DTS 6.1 Compatible will work on Dolby Digital 5.1 streams, too. Try out e.g. the “Black Hawk Down” disc. If the installation contains three surround channels, 6.1 Compatible will improve the surround experience on nearly all 5.1 encoded music and movie CD/DVD disc’s. Also 6.
An analogue or PCM input stream contains no information about the surround mode, therefore STEREO is selected as default, if ProLogic II is not selected under the config.ProLogic II menu. By pushing the “SURROUND MODE” key for more than one second or “STATUS” on the remote control, information about received bitstream will be displayed, e.g. PCM. The PR350 B can receive PCM inputs with sampling rates from 32kHz up to 96kHz.
6.1 Speakers The SPACE PR350 B contains extensive bass management adjustments, so that the bass signal can be re-routed to those loudspeakers capable of handling the low frequency information. The following selections can be made in the config.
The b) situation can be useful in situations, where the L, R speakers can handle deep bass information and extra bass is required. If the L and R speakers are not so well suited for the lowest frequencies, then chose a), eventually with lowest 60Hz cross over frequency. Further the Subwoofer – max bass ON can be selected in the Dolby Digital and DTS mode if extra bass is required. The Subwoofer – max bass setting will be stored in the memory bank and can therefore be set individually for each surround mode.
The following settings are possible: DYNAMIC HI (DTS + Dolby Digital) High level limit: 0.0 (disable high level limit function) 0.1 0.2 0.4 0.6 1.0 (maximise high level limit function) DYNAMIC LO (Dolby Digital) Low level boost: 0.0 (disable low level boost) 0.1 0.2 0.4 0.6 1.0 (maximise low level boost) 6.7 Volume scale It is possible to select two volume level settings: a progressive step size, where step size is large at low levels for rapid setting and small at normal listening levels, or a fixed 0.
6.9 Return to factory setting Each setting in the configuration menu will be stored even if the power is removed. However, if your entire set-up doesn’t work well, it may be desirable to reload the original factory settings. If this option is selected by the ”⇒” key, the user will be asked SURE ? in the display. If accepted, the user must push the “ENTER” key. Otherwise cancel by pushing “⇐” or “>VOL”.
6.14 Video input output For every input source, the user must select the correct video input format. Furthermore, the output format to the TV/Projector must be chosen as either RGB or Component. The DVD component input can be selected as pass-through with over 100MHz bandwidth. This is suitable for e.g. progressive DVD signals.

7.0 Your notes In this section you can fill in your own settings for the Space PR350 B, so you always have them, if you by mistake erase them.
APPENDIX A: Special Functions A.1 Communication between PR350 B and IA/PA350 B/PA250 B It is possible to remote control the functions in the IA250 B or the PA250 B, so that the operational mode of PA/IA250 B always will follow the operational mode of the PR350 B. Following functions in the PA/IA250 B can be remote controlled by the PR350 B.

A.2 A/D level Except for the Pure Audio inputs, all other analogue inputs will be converted to digital samples (A/D conversion) by the built-in 24 bit 96kHz high quality A/D converter. The digital audio samples are then used in the DSP circuit e.g. for further processing, e.g. Dolby ProLogic II.
