Rolls RM316: Independent Audio for Three Zones From One Install Mixer

The Rolls RM316 is a three-zone mixer that routes three mic or XLR-line inputs and three RCA sources to three separate zone outputs, each with its own level and paging. It exists for spaces divided into distinct areas that need different audio: a restaurant with a dining room, bar, and patio, or an office with several rooms. Switch-selectable routing sends any input to any combination of zones, and Euroblock zone outputs make it install-friendly. Per-zone remote volume and paging give staff local control without touching the rack. For a multi-area install that needs separate background music and announcements in each zone, the RM316 is built to keep them independent.

Three Zones, Independently Fed and Controlled

The RM316 sends audio to three balanced zone outputs, each able to carry its own blend of sources at its own level. Independent zones mean the dining room can play quiet background music while the bar runs something livelier and the patio stays off, all from one mixer. Because each zone has its own output stage and level, adjusting one area never disturbs the others. This is the core of zoned audio: one central mixer, three areas that behave as if they had their own systems. For any venue where different spaces need different sound, those three independent zone outputs are the whole reason the RM316 exists.

Switch-Selectable Routing to Any Zone

The RM316 uses switch-selectable routing so any of its inputs can feed any combination of the three zone outputs. That flexibility lets a music source play in all three zones while a paging mic reaches only the areas that need the announcement, or a second source play in just one room. Because routing is set by switches rather than fixed wiring, an installer can reconfigure the system as the venue's needs change. This matrix-style assignment is what turns three inputs and three zones into a genuinely flexible system rather than three fixed pairs. For a space whose audio needs shift by area and time of day, that routing freedom is a major practical advantage.

Balanced Euroblock Zone Outputs

All three zone outputs use balanced Phoenix, or Euroblock, connectors, the pluggable screw terminals favored for permanent commercial installs. Balanced outputs reject hum and noise over the long cable runs that reach amplifiers in different parts of a building. Euroblock connectors let a contractor land bare cable securely, then unplug a whole zone's wiring as a block for service without rewiring. That combination of balanced, connectorized outputs is exactly what install racks are designed around. For a fixed multi-zone system, those Euroblock zone outputs are the professional, serviceable way to distribute audio to each area's amplifier.

Per-Zone Remote Volume and Paging

The RM316 provides remote volume control for each zone and selectable ducking or paging per zone on the mic inputs. Per-zone remote volume lets a staff member adjust the bar's level from a wall plate without walking to the rack, which is how real venues operate day to day. Selectable per-zone paging means an announcement can automatically duck the music in just the zones that need it, leaving other areas undisturbed. That targeted paging keeps a kitchen call out of the dining room, for instance. For a working multi-area venue, per-zone control and paging are what make a central mixer feel like separate systems in each room.

Solid Audio With 15-Volt Phantom

The RM316 specifies a 20 Hz to 20 kHz frequency response, better than 75 dB signal-to-noise, and up to 60 dB of mic gain, with 15 VDC phantom power on the mic inputs. The full-range frequency response reproduces background music cleanly, not just speech, so each zone sounds good. Generous 60 dB mic gain brings a distant paging mic up to an intelligible level, and the 15-volt phantom runs small condenser mics that need powering. A 60 dB common-mode rejection ratio helps keep the balanced inputs quiet in an electrically noisy install. For a multi-zone system that has to sound clean in every area, those specs give the RM316 the performance the job requires.

Built for Restaurants, Offices, and Clubs

The RM316 is made for independent audio in three areas of a restaurant, office, or club, for zoned background music with per-zone paging, and for multi-room installs needing separate level control. A restaurant runs different music in the dining room, bar, and patio while paging only where needed, all from one 1U mixer. An office building feeds separate zones with background music and targeted announcements. Its rack chassis mounts once and runs from an external adapter, with Euroblock outputs wired to each zone's amplifier. For a three-area install that needs true independence per zone, the RM316 is the purpose-built mixer.
