But all the control and user interactions are performed in the digital domain. This allows us to incorporate options and possibilities not found in any standard analog equalizers:<\/p>\n<p class=\"font_8\">&#8211; Instant reset of all parameters<\/p>\n<p class=\"font_8\">&#8211; Rapid, precise and repeatable adjustments<\/p>\n<p class=\"font_8\">&#8211; Precisely linked stereo operation with the ease of a single control<\/p>\n<p class=\"font_8\">&#8211; DAW automation and recall of all available parameters<\/p>\n<p class=\"font_8\">\n<p class=\"font_8\">The digital section of the Stereo passive Equalizer is based around high speed, 32-bit micro-controller, with dedicated firmware programmed into its memory (with the possibility of updating the firmware via USB connection). It controls the parameters af analog filters, watches over the user interface, USB connectivity and other SPE functions.<\/p>\n<div id=\"comp-l0qo7s91\" class=\"_2Hij5\" data-testid=\"richTextElement\">\n<p class=\"font_7\">DAW integration<\/p>\n<\/div>\n<div id=\"comp-l0qo7saf\" class=\"_2Hij5\" data-testid=\"richTextElement\">\n<p class=\"font_7\">The Bettermaker Streo Passive Equalizer can communicate with your DAW via USB connection.<\/p>\n<p class=\"font_7\">The unit appears as a HID device and can be managed via Bettermaker Stereo Passive Equalizer Plugin<\/p>\n<div id=\"comp-l0qo7sde\" class=\"_2Hij5\" data-testid=\"richTextElement\">\n<p class=\"font_8\">Technical specification (all filters enabled, set flat):<\/p>\n<p class=\"font_8\">\n&#8211; Maximum input level: +24 dBu (balanced with 48k\u03a9 input impedance)<br \/>\n&#8211; Maximum output level: +27 dBu (balanced with 50\u03a9 + 50\u03a9 output impedance)<br \/>\n&#8211; Nominal audio level: +4 dBu<br \/>\n&#8211; Frequency response: 7 Hz \u2013 30kHz (-0.5 dB, ISO-R40 sweep)<br \/>\n&#8211; Frequency flatness: +\/- 0.2 dB (20Hz \u2013 20kHz, ISO-R40 sweep)<br \/>\n&#8211; Dynamic range: 101 dB (20kHz bandwidth, +24dBu)<br \/>\n&#8211; THD+N ratio: 0.009 % (20kHz bandwidth, +4dBu, 1kHz)<br \/>\n&#8211; THD ratio: 0.0025 % (+4dBu, 1kHz)<br \/>\n&#8211; CMRR: &gt; 70dB (20Hz \u2013 20kHz, IEC 60268-3)<br \/>\n&#8211; Crosstalk: &gt; 88dB (20Hz \u2013 20kHz, +18dBu, channel to channel)<br \/>\n&#8211; Max LF boost: 15 dB (set to 100 Hz)<br \/>\n&#8211; Max LF cut: 16 dB (set to 100 Hz)<br \/>\n&#8211; Max HF boost: 18 dB (all frequencies)<br \/>\n&#8211; Low boost\/cut frequencies: 20, 30, 60, 100 Hz<br \/>\n&#8211; High boost frequencies: 3, 4, 5, 6, 8, 10, 12, 16, 20, 28 kHz<br \/>\n&#8211; High cut frequencies: 5, 10, 20 kHz<br \/>\n&#8211; Control Resolution: 101 steps (Lo Boost, Lo Cut, Hi Boost, Bandwidth) &amp; 34 steps (Hi Cut)<br \/>\n&#8211; Output gain: +\/- 8 dB (0.1 dB resolution)<br \/>\n&#8211; Unit height: 2U<br \/>\n&#8211; Depth: 140 mm<br \/>\n&#8211; AC power consumption: 15W (2W in standby, with included 100-240VAC power adapter)<\/p>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Bettermaker\u00ae Stereo Passive Equalizer (SPE) is for those who seek outstanding EQ quality with the convenience of fast and precise recall and automation.
