It is specifically designed for those whose amplifier, soundbar, or active speakers have insufficient or no analog audio inputs. This allows you, for example, to connect a turntable with a phono preamp to an audio system equipped with a digital input. This device makes compatibility easy and expands the usability of old analog equipment in modern systems.<\/p>\n<h3>Integrating Analog and Digital Audio<\/h3>\n<p>The AD12 E converts an analog stereo signal (2 x RCA) into a digital audio signal that can be transmitted via either an optical Toslink connection or a coaxial RCA connection. This enables, for example, connecting a turntable to a digital amplifier or speaker even if they lack analog inputs. The device supports simultaneous audio output from both outputs, allowing you to use both optical and coaxial digital connections at the same time.<\/p>\n<h3>High-Quality Sound and Technical Features<\/h3>\n<p>The Marmitek Connect AD12 E uses a high-quality ADC chip that ensures clean and accurate audio conversion. The digital signal is in LPCM format, with a 48 kHz sampling rate and 24-bit depth, meeting common audio industry standards. The sound quality is enhanced by low noise (signal-to-noise ratio \u2265 80 dB) and excellent channel separation (90 dB). The frequency response covers the entire audible range of 20 Hz &#8211; 20 kHz \u00b1 3 dB, delivering natural sound reproduction.<\/p>\n<h3>Practical Size and Power Supply<\/h3>\n<p>The device is compact, measuring 23 x 51 x 80 mm and weighing only 45 grams, so it fits easily into any audio system or home theater setup. It is powered by a 100-240 VAC 50\/60 Hz supply and comes with a 5 VDC adapter, making power supply easy and safe.<\/p>\n<h3>Compatibility and Use Cases<\/h3>\n<p>The AD12 E is designed especially for situations where there are few or no analog audio inputs. It is ideal for turntables with built-in or separate phono preamps and enables their connection to modern devices equipped with digital inputs. This way, old devices can work seamlessly with new technology.<\/p>\n<h3>Features<\/h3>\n<ul>\n<li>Converts analog stereo signal to digital (optical Toslink or coaxial RCA)<\/li>\n<li>Allows connecting a turntable to an amplifier or speakers with digital inputs<\/li>\n<li>High-quality ADC chip ensures excellent sound quality<\/li>\n<li>Uncompressed LPCM digital stereo signal at 48 kHz sampling rate<\/li>\n<li>Simultaneous audio output from optical and coaxial connections<\/li>\n<li>Suitable for devices with few or no analog audio inputs<\/li>\n<\/ul>\n<h3>Technical Specifications<\/h3>\n<ul>\n<li><strong>Input connection:<\/strong> 2 x RCA (stereo)<\/li>\n<li><strong>Output connections:<\/strong> 1 x optical Toslink, 1 x coaxial RCA<\/li>\n<li><strong>Sampling rate:<\/strong> 48 kHz, 24-bit<\/li>\n<li><strong>Audio formats:<\/strong> 2-channel PCM stereo<\/li>\n<li><strong>Signal-to-noise ratio:<\/strong> \u2265 80 dB<\/li>\n<li><strong>Channel separation:<\/strong> 90 dB<\/li>\n<li><strong>Frequency response:<\/strong> 20 Hz &#8211; 20 kHz \u00b1 3 dB<\/li>\n<li><strong>Dimensions (H x W x D):<\/strong> 23 x 51 x 80 mm<\/li>\n<li><strong>Weight:<\/strong> 45 grams<\/li>\n<li><strong>Power:<\/strong> 100-240 VAC 50\/60 Hz, 5 VDC adapter<\/li>\n<\/ul>\n<h3>Package Contents<\/h3>\n<ul>\n<li>Marmitek Connect AD12 E analog &gt; digital converter<\/li>\n<li>5 VDC power adapter<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<ul>\n<li>Simultaneous optical and coaxial output<\/li>\n<li>Compact size and lightweight<\/li>\n<li>High-quality sound quality with ADC chip<\/li>\n<li>Small and lightweight device weighing only 45 g<\/li>\n<li>Suitable for turntables with a phono preamplifier<\/li>\n<\/ul>\n","protected":false},"featured_media":999999999,"template":"","meta":{"_acf_changed":false},"product_brand":[],"product_cat":[19925,39518,39520,16741,36727,19924],"product_tag":[],"class_list":["post-1321978","product","type-product","status-publish","has-post-thumbnail","product_cat-audio-cables-and-adapters","product_cat-audio-and-video-cables-en","product_cat-audio-cables-and-adapters-en","product_cat-tv-ja-video","product_cat-audio-ja-video-audio-and-video-en","product_cat-audio-and-video-cables","first","onbackorder","taxable","shipping-taxable","purchasable","product-type-simple"],"acf":[],"_links":{"self":[{"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/product\/1321978","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:attachment":[{"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/media?parent=1321978"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/product_brand?post=1321978"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/product_cat?post=1321978"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/digibit.ee\/en\/wp-json\/wp\/v2\/product_tag?post=1321978"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
