Each channel contains switches for 48V phantom power, a low cut filter and phase reversal. Amplification can be set between 6 and 60 dB. LEDs for signal, clip, and activated phantom power give a complete overview on the unit&#8217;s status. When the special Clip Hold mode is activated, any detected clip-state will cause the corresponding LED to flash once per second. With this, the user gets a long-term peak detection, and no longer needs to constantly watch the LEDs. At the same time momentary overloads are still displayed correctly.<\/p>\n<p>Frontside switches include power on\/off and output level, for a choice of -10 dBV, +4 dBu or Hi Gain (+19 dBu) as reference level. This unusual feature offers two advantages. First, the reference level can be easily switched to match any of RME&#8217;s current interface devices, from HDSP 9632 through Multiface up to the renowned ADI-8 series converters. Second, the Signal to Noise ratio is optimized, and the Clip-LED will exactly match the ones of the ADI-8 (2 dB below 0 dBFS).<\/p>\n<p>The balanced line level output signal is available at the back of the unit via 8 stereo TRS jacks. The specially developed, internal hi-performance switch mode power supply lets the OctaMic II operate in the range of 100V to 240V AC. It is short-circuit-proof, has an integrated line-filter, is fully regulated against voltage fluctuations, and suppresses mains interference.<\/p>\n<h1 class=\"underline\">AD-Conversion<\/h1>\n<p>The 8-Channel AD-conversion of the OctaMic II operates at up to 192 kHz. The digitized signal is available simultaneously at the double ADAT output (S\/MUX, up to 96 kHz), and at a DB-25 connector (4 AES\/EBU outputs, up to 192 kHz). The digital part can be clocked internally (master) and externally via word clock, AES\/EBU and SPDIF.<\/p>\n<p>RME&#8217;s outstanding\u00a0SteadyClock<sup>(TM)<\/sup>\u00a0ensures perfect AD-conversion, as jitter on the external sync-sources is nearly completely removed. All settings are done via DIP-switches on the back of the OctaMic II. Analog outputs and both digital outputs operate fully simultaneously. The choice of reference level affects the analog outputs only, the signal\/clip indication and the AD-conversion will react only to the Gain-pots.<\/p>\n<h1 class=\"underline\">Tech Specs<\/h1>\n<p class=\"dashlist\"><strong>8 balanced XLR\/TRS mic\/line inputs<\/strong><\/p>\n<p class=\"dashlist\"><strong>54 dB gain range<\/strong><\/p>\n<p class=\"dashlist2\"><strong>Input impedance:<\/strong>\u00a0XLR 2 kOhm, TRS 5 kOhm<\/p>\n<p class=\"dashlist\"><strong>Analog input level:<\/strong>\u00a0from -40 dBu up to +21 dBu<\/p>\n<p class=\"dashlist\"><strong>Maximum output level:<\/strong>\u00a0+21 dBu<\/p>\n<p class=\"dashlist\"><strong>Output impedance:<\/strong>\u00a075 Ohm<\/p>\n<p class=\"dashlist\"><strong>Output level switchable<\/strong>\u00a0Hi Gain \/ +4 dBu \/ -10 dBV<\/p>\n<p class=\"dashlist2\"><strong>Signal to noise ratio (SNR):<\/strong>\u00a0129 dB EIN @ 150 Ohm<\/p>\n<p class=\"dashlist2\"><strong>THD:<\/strong>\u00a0&lt; 0.0005 % @ 30 dB Gain<\/p>\n<p class=\"dashlist\"><strong>Large frequency range (200 kHz)<\/strong>\u00a0with special EMI input filtering<\/p>\n<p class=\"dashlist\"><strong>Frequency response<\/strong>\u00a0-0.5 dB: 5 Hz &#8211; 200 kHz<\/p>\n<p class=\"dashlist2\"><strong>Hi-pass filter:<\/strong>\u00a080 Hz, 18 dB\/oct.<\/p>\n<p class=\"dashlist\"><strong>Line Out:<\/strong>\u00a01\/4&#8243; TRS (6.3 mm stereo jack), servo-balanced<\/p>\n<p class=\"dashlist\"><strong>Phantom power:<\/strong>\u00a0+48 Volt switchable per channel<\/p>\n<p class=\"dashlist\"><strong>Internal wide range switching power supply<\/strong>\u00a0100-240 Volt AC<\/p>\n<p class=\"dashlist2\">Unbeatable price\/performance ratio!<\/p>\n<h2>AD conversion<\/h2>\n<p class=\"dashlist\"><strong>SNR<\/strong>: &gt;110 dB(A)<\/p>\n<p class=\"dashlist\"><strong>Supported sample rates<\/strong>: 28 kHz &#8211; 200 kHz<\/p>\n<p class=\"dashlist\"><strong>THD<\/strong>: &lt; 0.0003 %, &lt; -110 dB<\/p>\n<p class=\"dashlist\"><strong>Sync Sources:<\/strong>\u00a0AES\/EBU (also SPDIF coaxial), wordclock, internal<\/p>\n<p class=\"dashlist2\">SteadyClock<sup>(TM)<\/sup>\u00a0ensures best sound quality even with jittery external clocks<\/p>\n","protected":false},"excerpt":{"rendered":"<div class=\"columnright280\">\n<div class=\"grey-rounded-box-text\">\n<ul class=\"listbullet\">\n<li>8 x Mic \/ Line Preamp Input (XLR\/TRS Combo)<\/li>\n<li>8 x Line Output (TRS balanced)<\/li>\n<li>8 x AD-converter (up to 192 kHz)<\/li>\n<li>2 x ADAT Output (S\/MUX, up to 96 kHz)<\/li>\n<li>4 x AES\/EBU Output (D-sub, up to 192 kHz)<\/li>\n<li>1 x AES\/SPDIF Sync Input<\/li>\n<li>Phase, Low Cut and Phantom power per channel<\/li>\n<li>Clip Hold Memory<\/li>\n<\/ul>\n<\/div>\n<\/div>\n","protected":false},"featured_media":13395,"template":"","meta":[],"pwb-brand":[187],"product_brand":[],"product_cat":[1029],"product_tag":[521],"class_list":["post-8884","product","type-product","status-publish","has-post-thumbnail","pwb-brand-rme","product_cat-preamplificadores-y-canales","product_tag-rme","first","onbackorder","sale","taxable","shipping-taxable","purchasable","product-type-simple"],"brands":[{"id":187,"name":"RME","slug":"rme"}],"_links":{"self":[{"href":"https:\/\/masteringmansion.com\/pro-audio\/wp-json\/wp\/v2\/product\/8884","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/masteringmansion.com\/pro-audio\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/masteringmansion.com\/pro-audio\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/masteringmansion.com\/pro-audio\/wp-json\/wp\/v2\/media\/13395"}],"wp:attachment":[{"href":"https:\/\/masteringmansion.com\/pro-audio\/wp-json\/wp\/v2\/media?parent=8884"}],"wp:term":[{"taxonomy":"pwb-brand","embeddable":true,"href":"https:\/\/masteringmansion.com\/pro-audio\/wp-json\/wp\/v2\/pwb-brand?post=8884"},{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/masteringmansion.com\/pro-audio\/wp-json\/wp\/v2\/product_brand?post=8884"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/masteringmansion.com\/pro-audio\/wp-json\/wp\/v2\/product_cat?post=8884"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/masteringmansion.com\/pro-audio\/wp-json\/wp\/v2\/product_tag?post=8884"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
