In a compact 1RU 19\" rack format, the SAMI-402 provides a well-specified four-channel analogue stereo mixing solution with three MIC\/LINE stereo inputs and one dedicated LINE stereo input, accommodating a flexible combination of microphone and line-level sources from a single rack-mountable unit. The result is a clean, professional and highly practical mixer that simplifies installation audio system design without compromising on features or audio quality.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eHigh-Quality Audio Performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe SAMI-402 delivers excellent audio performance across all input types. Line inputs achieve a frequency response of 10Hz to 50kHz (-1dB), THD+Noise of less than 0.005% and a signal-to-noise ratio of greater than 100dB — figures that reflect the quality of Ecler's engineering heritage. Balanced MIC inputs achieve a frequency response of 10Hz to 30kHz (-1dB) and SNR greater than 85dB, with a common mode rejection ratio of greater than 60dB at 1kHz for clean, interference-free microphone amplification. All MIC inputs support +18V phantom power for condenser microphones, and microphone sensitivity can be fine-tuned via rear panel adjustment for precise level matching across different microphone types and installation scenarios.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eTalkover, Tone Control \u0026amp; Flexible Output\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe SAMI-402 includes a number of features specifically tailored for professional installation use. A 3-band tone control section — with Bass at 100Hz ±15dB, Mid at 2kHz ±15dB and Treble at 10kHz ±15dB — allows tonal shaping of the mix output to suit different room acoustics and system requirements. A talkover (priority) function is assignable from each MIC\/LINE input over the mix bus, with a 2-second release time and -30dB ducking effect — ensuring microphone announcements are always clearly heard above background music. The main mix output is switchable between stereo and mono operation, with an additional AUX\/REC output for recording or zone feed applications. Output levels are internally selectable at 0dB or +6dB to suit different downstream equipment requirements.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eRemote Control \u0026amp; Safety Integration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe SAMI-402 includes a MUTE remote control input triggered by external dry contact closure — enabling straightforward integration with fire detection systems, emergency alert systems and other safety devices for automatic audio muting in an emergency. This makes the SAMI-402 a compliant and practical choice for commercial installations where fire safety integration is a requirement. Power LED, MUTE LED and VU-meter level LEDs provide clear front panel status monitoring at all times. The unit is passively cooled for silent operation and is supplied with a ±17.5VDC multi-plug external PSU, Euroblocks, rubber feet and mini jumpers.\u003c\/p\u003e\n\u003ch3\u003eEcler SAMI-402 Key Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e4-Channel 19\" 1RU Installation Mixer:\u003c\/strong\u003e 3 x MIC\/LINE stereo inputs and 1 x LINE stereo input in a compact, professional rack-mount format.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e+18V Phantom Power:\u003c\/strong\u003e Available on all MIC inputs for condenser microphone compatibility.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e3-Band Tone Control:\u003c\/strong\u003e Bass (100Hz ±15dB), Mid (2kHz ±15dB) and Treble (10kHz ±15dB) for tonal shaping to suit different room acoustics.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eTalkover (Priority) Function:\u003c\/strong\u003e Assignable from each MIC\/LINE input over the mix bus with 2-second release time and -30dB ducking effect.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eAdjustable MIC Sensitivity:\u003c\/strong\u003e Rear panel microphone sensitivity adjustment (±15dB) for precise level matching across different microphone types.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMain Mix Output:\u003c\/strong\u003e Switchable stereo\/mono output via 3-pin Euroblock with internally selectable output level (0dB or +6dB).\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eAUX\/REC Output:\u003c\/strong\u003e Additional stereo RCA output for recording or zone feed applications.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eMUTE Remote Control Input:\u003c\/strong\u003e External dry contact closure for integration with fire detection systems and other safety devices.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eExcellent Audio Specifications:\u003c\/strong\u003e Line THD+Noise \u0026lt;
