The Russound MCA-88X Digital multi-zone controller amplifier streamer provides up to eight zones of distributed audio. Scalable to 48 zones, the MCA-88X provides numerous options to tailor every room in residential or light commercial distributed audio systems. A variety of input options have been engineered into the MCA-88X to connect up to 7 individual sources in addition to its built-in XStream streamer. AV source input options include up to 7 Analog, with up to 3 Digital (up to 3 coax, or 2 coax and 1 optical), including 1 paging and 1 Bluetooth extender connection. The Bluetooth connection allows the installation of the MCA-88X in an equipment rack while remotely locating the optional Russound BTC-1X Bluetooth receiver up to 300’ away in or near the room where the Bluetooth source will be located. Additionally, the BTC-1X improves audio quality through the high performance aptX audio codec. An RNET link allows for metadata transmission, linking multiple MCA controllers and connection to all Russound RNET Smart Sources like the ST1 AM/FM external tuner.

All MCA-Series products are Ethernet enabled devices allowing for IP based features and control. RIO (Russound I/O) allows Russound IP based control systems to integrate with, control, and communicate bi-directionally through an open protocol. In addition to dedicated keypads and touchscreen control options, the free MyRussound App (iOS and Android) controls all Russound Ethernet connected products on the LAN including the MCA-88X and its source components.

The MCA-88X features 6 zones of high quality amplification, providing a robust 40 watts of power per channel. All eight zones are equipped with fixed or variable line-level outputs for outboard amplification, wireless expansion or subzone use. Additionally, an RS-232 port for integration with serial-connected home automation systems is available for utilization on the rear panel of the MCA-88X.

Custom audio settings, party modes, do not disturb, source and zone linking, and all-on/all-off participation are standard features. The MCA-88X has alarm and sleep timers, a Home Theater trigger and one 12VDC trigger output for power management and control. Source eight can serve as a paging input for connection to a 3rd party paging or phone system.

With Russound keypads or touchscreens, the MCA-88X communicates vital information such as preset names, station ID, artist, song titles and album art depending on the capabilities of the source being used. The simpler SLK-1 keypad can also be used for areas where basic control is sufficient such as entry/exit areas of a home or business or any area where the MyRussound App might be the predominant control interface.

The Stealth Acoustics SA2400MKII is a high-current two-channel amplifier with powerful built-in digital signal processing functions suitable as a low distortion power source for Stealth Acoustics speakers, Stealth subwoofers, or other un-powered speakers 

Stealth Acoustics Pro-Power Series 2 Channel Power Amplifier

Intended for distributed audio, fixed installations, or home theater applications, the SA2400MKII mounts using the supplied removable rack ears in a standard 19” (482 mm) equipment rack requiring only two RU spaces (3-1/2” – 89 mm), or may stack with other free-standing components. The SA2400MKII delivers a solid 310 watts per-channel into an 8Ω load and 450 watts per-channel into 4Ω.

The SA2400MKII’s internal DSP functions may be programmed for each channel independently or together and include 11 bands of fully-parametric EQ, variable High and Low Pass filters with selectable slopes, fully-programmable limiter stage and delay functions. All parameters may be programmed using front panel controls or via a USB connected computer utilizing Stealth Signal Management System software (SSMS).

For maximum flexibility integrating into any audio system, the SA2400MKII includes RCA unbalanced line level, balanced XLR line level, and phoenix speaker level inputs for each channel, all with “pass-through” output connectors. Line level pass through outputs may be programmed as either “pre” or “post” DSP feeds to facilitate extending DSP tuning to additional amplifiers. The speaker level input/pass-through connections allow the SA2400MKII to feed directly from full-range speaker lines, anywhere in the system and will track the speaker’s output level. A stereo optical input is provided for connecting digital sources to the amplifier. Inputs may be mapped to either channel and may be “mono-summed” via programming. The SA2400MKII amplifier output connections are via 5-way binding posts designed to accept heavy gauge speaker wires.

10 internal, remotely re-callable, read-write presets allow the amplifier to quickly change profile states for different modes of usage, or to load factory speaker optimization curves for Stealth invisible and environmental speakers and subwoofers. Users may store and recall unlimited amplifier profile files via the SSMS App. A selectable automatic turn-on feature activates the amplifier only when audio signals are present, or the 12V trigger function may be utilized to activate and deactivate the amplifier, along with other system components. The IR control functionality also allows for remote control of master volume and preset selection via most 3rd-party control systems. Quiet 8-stage cooling fans automatically engage as required. The front panel includes direct master volume and menu access controls as well as an LCD display window and dual clip indicators. 115VAC through 230VAC 50/60 input line voltages are automatically accommodated via the auto-sensing IEC power inlet. The Stealth Acoustics SA2400MKII amplifier is covered by a 2-Year manufacturer’s warranty.

Stealth Acoustics Pro-Power Series Monaural Power Amplifier

Intended for whole house audio or home theater bass applications, the SA255 MKII may stack with other components or mount in a standard 19” equipment rack requiring two RU spaces (3-1/2”) with the provided removable rack mount ears. The SA255 MKII delivers a solid into an 8Ω load and into 4Ω.  A variable low pass, 18db per octave filter allows for infinite crossover points from 50Hz to 100Hz.

With a full complement of input and output connectors, the SA255 MKII is easily integrated into any audio system. Inputs include RCA line level, balanced XLR line level, and phoenix connector speaker level, all with pass-through capability. The speaker level input/pass-through connections allow the SA255 MKII to feed directly from full-range speaker lines, anywhere in the system. The SA255 MKII’s amplifier output connection is via a 5-way binding post designed to accept heavy gauge speaker wires. A selectable automatic turn-on feature activates the amplifier only when audio signals are present. Other features include an internal, quiet, 8-stage cooling fan that automatically engages as required.

Front panel controls include volume control, variable low pass filter, phase control, power switch and six power output monitor LED’s. Rear power controls consist of filter bypass switch for full range operation, no signal mute switch and 3-position panel graphics control switch. 115VAC and 230VAC input line voltages are selectable, via a rear panel switch.

The Stealth Acoustics SA255 MKII subwoofer amplifier is covered by a 2-Year manufacturer’s warranty.

The Stealth Acoustics SA255 MKII is an integrated monaural subwoofer amplifier/crossover system designed as a low distortion power source for Stealth Acoustics invisible subwoofer panels or other un-powered subwoofers.
