Each channel\u2019s parameters can be individually set, allowing for flexible system designs such as a full 4-way system with all crossovers and delays, an active 2-way front system with subwoofer and rear speakers, or any combination supported by the 8 outputs.<\/p>\n<p data-start=\"618\" data-end=\"899\">When using speaker-level inputs, the unit automatically activates upon detecting a signal, eliminating the need for a separate remote turn-on from the head unit. Additionally, the DSP can pass turn-on voltage to connected amplifiers, simplifying integration with factory systems.<\/p>\n<p data-start=\"901\" data-end=\"928\"><strong data-start=\"901\" data-end=\"926\">Optional accessories:<\/strong><\/p>\n<ul data-start=\"929\" data-end=\"1044\">\n<li data-start=\"929\" data-end=\"1002\">\n<p data-start=\"931\" data-end=\"1002\">GZDSP BT-STICK for wireless audio streaming directly to the processor<\/p>\n<\/li>\n<li data-start=\"1003\" data-end=\"1044\">\n<p data-start=\"1005\" data-end=\"1044\">Wired remote control GZDSP REM 4-8XII<\/p>\n<\/li>\n<\/ul>\n<p data-start=\"1046\" data-end=\"1096\" data-is-last-node=\"\" data-is-only-node=\"\"><strong data-start=\"1046\" data-end=\"1057\">Awards:<\/strong><br data-start=\"1057\" data-end=\"1060\" \/>EISA In-Car Best Value DSP 2020\u20132021<\/p>\n<h3 class=\"block-title\">Specifications<\/h3>\n<div class=\"block-content\">\n<p>&#8211; Type 8-channel signal processor (DSP) with 4 input channels<\/p>\n<\/div>\n<p>&#8211; Sampling frequency 48 kHz \/ resolution 56-bit<br \/>\n&#8211; Frequency range 20 Hz \u2013 20 KHz (-3 dB)<br \/>\n&#8211; SNR \/ line input \u2265115 dB<br \/>\n&#8211; SNR \/ high level input \u2265105 dB<br \/>\n&#8211; THD \/ line input 0.002 %<br \/>\n&#8211; THD \/ high level input 0.010 %<br \/>\n&#8211; DSP chipset 2x Analog Devices SigmaDSP<br \/>\n&#8211; Sensitivity Line input (RCA) max. 855 mV RMS<br \/>\n&#8211; High level input max. 8.0 V RMS<br \/>\n&#8211; Input impedance Line input (RCA) \u226520 k\u03a9<br \/>\n&#8211; High level input 39 \u03a9<br \/>\n&#8211; Output voltage \/ channel \u22652.5 V<br \/>\n&#8211; Remote current max. 500 mA<br \/>\n&#8211; Remote input voltage 10 V<br \/>\n&#8211; Switching voltage \/ speaker input 1.3 V<br \/>\n&#8211; Switching voltage \/ line input 10 mV<br \/>\n&#8211; Turn on delay 3 seconds<br \/>\n&#8211; Recommended fuse value 2 A<br \/>\n&#8211; Software compatibility Microsoft Windows\u2122 XP SP3, Vista, 7, 8, 8.1,10<br \/>\n&#8211; Preset memory 6 presets (individually assignable)<br \/>\n&#8211; Gain range -60 bis +6 dB<br \/>\n&#8211; Equalizer 8x parametric 10 band EQ (20 Hz \u2013 20 kHz) with adjustable Q<br \/>\n&#8211; Time delay 0 \u2013 8 ms \/ 0 \u2013 272 cm \/ 0 \u2013 107\u201c<br \/>\n&#8211; Crossover 6 \/ 12 \/ 18 \/ 24 dB\/oct. slope with selectable filter characteristic<br \/>\n&#8211; Phase correction 0\u00b0 \/ 180\u00b0<br \/>\n&#8211; Optionally available accessory GZDSP BTS 4-8XII<br \/>\nGZDSP REM 4-8XII<br \/>\n&#8211; Dimensions (W x L x H)169 x 114 x 27 mm..<\/p>\n","protected":false},"excerpt":{"rendered":"<p><strong data-start=\"0\" data-end=\"56\" data-is-only-node=\"\">DSP for integration with the car&#8217;s factory head unit<\/strong><br data-start=\"56\" data-end=\"59\" \/>4 input channels<br data-start=\"75\" data-end=\"78\" \/>8 output channels<\/p>\n","protected":false},"featured_media":17302,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"etheme_brands":[{"term_id":291,"name":"Ground zero","slug":"ground-zero","term_group":0,"term_taxonomy_id":291,"taxonomy":"brand","description":"","parent":0,"count":370,"filter":"raw"}],"product_cat":[352],"product_tag":[357],"_links":{"self":[{"href":"https:\/\/roadtunes.lv\/index.php?rest_route=\/wp\/v2\/product\/23672"}],"collection":[{"href":"https:\/\/roadtunes.lv\/index.php?rest_route=\/wp\/v2\/product"}],"about":[{"href":"https:\/\/roadtunes.lv\/index.php?rest_route=\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/roadtunes.lv\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=23672"}],"version-history":[{"count":3,"href":"https:\/\/roadtunes.lv\/index.php?rest_route=\/wp\/v2\/product\/23672\/revisions"}],"predecessor-version":[{"id":30549,"href":"https:\/\/roadtunes.lv\/index.php?rest_route=\/wp\/v2\/product\/23672\/revisions\/30549"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/roadtunes.lv\/index.php?rest_route=\/wp\/v2\/media\/17302"}],"wp:attachment":[{"href":"https:\/\/roadtunes.lv\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=23672"}],"wp:term":[{"taxonomy":"brand","embeddable":true,"href":"https:\/\/roadtunes.lv\/index.php?rest_route=%2Fwp%2Fv2%2Fetheme_brands&post=23672"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/roadtunes.lv\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_cat&post=23672"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/roadtunes.lv\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct_tag&post=23672"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
