Designed for installed AV, broadcast, and live sound applications, the RM89 delivers a 96 dB signal-to-noise ratio and less than 0.025% THD for clean, reliable mixing in demanding environments.\u003c\/p\u003e\n\n\u003cp class=\"pd-overview-2\"\u003eFor integrators and engineers searching for a rack-mount mixer for conference rooms, houses of worship, or broadcast facilities, the RM89 handles both microphone and line-level signals on the same input bus without external adapters. Each of the six XLR channels accepts mic-level signals down to -14 dBV or line-level balanced XLR sources up to 24 dBV, giving system designers the flexibility to accommodate diverse signal sources in a single compact chassis. The two RCA stereo source inputs extend the channel count further, making this an efficient solution for multi-source installed systems.\u003c\/p\u003e\n\n\u003cp class=\"pd-overview-3\"\u003eThe RM89 includes bass and treble tone controls (+\/-10 dB at 500 Hz and 5 kHz) for the source inputs, a master level control, and a mono summing function that collapses the stereo mix to mono output — essential for single-speaker distributed audio systems and 70V\/100V installations. With balanced XLR output capable of driving loads at up to 20 dBV max, the RM89 integrates cleanly into professional signal chains without the need for additional output buffering.\u003c\/p\u003e\n\n\u003ch3 class=\"pd-features-heading\"\u003eKey Features of the Rolls RM89 Mic \/ Line Mixer\u003c\/h3\u003e\n\u003cul class=\"pd-features\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6 Balanced XLR Mic\/Line Inputs:\u003c\/strong\u003e Accommodates both microphone and line-level sources on each XLR channel, eliminating the need for separate preamps or DI boxes in mixed-source installations.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndividual Phantom Power per XLR Channel:\u003c\/strong\u003e Each XLR input carries independently switchable 15V phantom power, enabling condenser microphones to be mixed alongside dynamic mics and line sources on the same unit.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e2 Stereo RCA Source Inputs with Level Control:\u003c\/strong\u003e Expands the effective channel count and integrates playback devices, background music sources, or auxiliary gear with dedicated level trims for each source.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBass and Treble EQ for Source Inputs:\u003c\/strong\u003e Provides +\/-10 dB shelving control at 500 Hz (bass) and 5 kHz (treble), allowing tone shaping of source inputs without external processing.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMono Sum Output:\u003c\/strong\u003e Collapses the stereo mix to mono with a single control, ensuring compatibility with single-speaker or distributed mono audio systems.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e96 dB Signal-to-Noise Ratio:\u003c\/strong\u003e Delivers a -80 dB noise floor and less than 0.025% THD, providing the clean signal integrity required for professional installed and broadcast applications.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1U Rack-Mount Design (19\" Width):\u003c\/strong\u003e Fits standard 19-inch equipment racks, making it an efficient choice for AV rack buildouts in permanent or touring installations.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 class=\"pd-specs-heading\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul class=\"pd-specs\"\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChannels:\u003c\/strong\u003e 8 (6 XLR + 2 Stereo RCA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eXLR Input Type:\u003c\/strong\u003e Mic level or line level balanced XLR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRCA Input Type:\u003c\/strong\u003e Stereo line level\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdditional Input:\u003c\/strong\u003e 3.5mm (1)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTotal Connectors:\u003c\/strong\u003e 7 XLR, 3 Stereo RCA, 1 x 3.5mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Impedance (Mic):\u003c\/strong\u003e 600 Ohms, balanced XLR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInput Impedance (Source):\u003c\/strong\u003e 22K Ohms, RCA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMax Input Level (Mic):\u003c\/strong\u003e -14 dBV mic level;
