Ecler SAMI-612 6-Channel 19" Analogue Stereo Rack Mixer
DETAILS
The Ecler SAMI-612 is a 6-Channel 19" Analogue Stereo Installation Rack Mixer featuring six MIC/LINE stereo inputs, per-channel 3-band tone control, front panel direct microphone input, talkover priority and a MUTE remote control port.
Comprehensive and professional 1RU mixing solution for retail, education, corporate, hospitality and sports and wellness installations.
The Ecler SAMI-612 steps up the SAMI series with six MIC/LINE stereo inputs — providing greater input capacity for more complex installation audio systems where multiple microphone and line-level sources need to be managed from a single, rack-mountable mixing unit.
Designed specifically for professional fixed audio installations across retail stores, educational facilities, corporate offices, hospitality venues and sports and wellness spaces, the SAMI-612 combines comprehensive mixing capability with the practical installation features that professional integrators and installers require — all in a compact 1RU 19" rack format. A dedicated stereo MIX input also allows a second mixer to be connected directly to the mixing bus, enabling the number of inputs to be expanded further for larger or more complex system designs.
Per-Channel 3-Band Tone Control
One of the standout features of the SAMI-612 over the smaller SAMI-402 is its per-channel 3-band tone control section — accessible via screwdriver on each individual input channel. Bass (100Hz ±15dB), Mid (2kHz ±15dB) and Treble (10kHz ±15dB) adjustment is available independently for every channel, providing a level of tonal control that is fundamental to achieving a well-balanced and professional microphone mix in a fixed installation environment. Where a single global EQ can only compensate for general tonal imbalances, per-channel EQ allows each individual microphone or source to be tailored precisely — accounting for differences in microphone type, placement and the characteristics of individual voices.
High-Quality Audio Performance
The SAMI-612 maintains the same high audio quality standards as the rest of the SAMI series. Line inputs achieve a frequency response of 10Hz to 50kHz (-1dB), THD+Noise less than 0.005% and SNR greater than 100dB. Balanced MIC inputs achieve a frequency response of 10Hz to 30kHz (-1dB) and SNR greater than 85dB with CMRR greater than 60dB at 1kHz. All MIC inputs support +18V phantom power, and microphone sensitivity is adjustable via rear panel controls for precise level matching across all channels.
Front Panel Direct Mic Input, Talkover & Safety Integration
Channel 1 of the SAMI-612 features a dedicated front panel jack connector for direct microphone connection — a practical feature for installations where quick and convenient front-panel microphone access is required without routing cables to the rear of the rack. Channel 1 also carries the talkover (priority) function with internally adjustable release time, automatically ducking the mix output by -30dB when the channel 1 microphone is active. A MUTE remote control input — triggered by external dry contact closure — enables integration with fire detection systems and emergency alert devices for automatic audio muting. A VU-meter monitors the mix signal level, and the main output is switchable between stereo and mono operation.
