(SA and MA models) Energy efficient Class D stereo or mono amplifier:
•
2 x 50 watts @ 4 ohms; 2 x 25 watts @ 8 ohms
•
1 x 100 watts @ 70 volts — The SA models offers a stereo power amplifier with
•
50 watts per channel into 4 ohms and 25 watts per channel into 8 ohms, while the
MA 70 models offer a mono 70 volt power amplifier with 100 watts rms output.
Both amplifiers feature an Extron exclusive, efficient, advanced Class D amplifier
design with patented Class D Ripple Suppression (CDRS) technology. CDRS
provides a smooth, clean audio waveform and an improvement in signal fidelity
over conventional Class D amplifier designs. CDRS eliminates the high frequency
switching ripple characteristic of Class D amplifiers, a source of RF emissions which
can interfere with sensitive AV equipment such as wireless microphones.
• Supports HDMI video — Includes data rates up to 10.2 Gbps, Deep Color up to
12-bit, 3D, and HD lossless audio formats.
HDCP compliant — Fully supports HDCP-encrypted sources, with selectable
•
authorization for unencrypted content.
• Key Minder — Authenticates and maintains continuous HDCP encryption between
input and output devices to ensure quick and reliable switching in professional AV
environments, while enabling simultaneous distribution of a single source signal to one
or more displays.
• SpeedSwitch Technology — Provides exceptional switching speed for HDCP-
encrypted content
HDCP authentication and signal presence confirmation — Provides real-time
•
verification of HDCP status for each digital video input and output. This allows for
simple, quick, and easy signal and HDCP verification through RS-232, USB, or
Ethernet, providing valuable feedback to a system operator or helpdesk support staff.
• HDCP visual confirmation — Provides a green signal when encrypted content is sent
to a non-compliant display. A full-screen green signal is sent when HDCP-encrypted
content is transmitted to a non-HDCP compliant display, providing immediate visual
confirmation that protected content cannot be viewed on the display.
HDMI to DVI Interface format correction — Automatically enables or disables
•
embedded audio and infoframes, and sets the correct color space for proper
connection to HDMI and DVI displays.
• EDID Minder — Automatically manages EDID communication between connected
devices. EDID Minder ensures that all sources power up properly and reliably output
content for display.
• QuickSwitch Front Panel Controller (QS-FPC) with tri-color backlit buttons
— Provides a discrete button for each input and output, allowing for simple, intuitive
operation. Buttons can be custom labeled for easy identification. The buttons illuminate
red, green, or amber depending on function, for ease of use in low-light environments.
View I/O mode — Users can easily view which inputs and outputs are actively
•
connected.
• Presets — Frequently used I/O configurations may be recalled either from the
QuickSwitch Front Panel Controller, Ethernet, USB, or RS-232 serial control.
• Output muting control — Provides the capability to mute one or all outputs at
any time. This allows, for example, content to be viewed on a local monitor prior to
appearing on the main presentation display.
• Aspect ratio control — For inputs delivered to the scaled (HDMI and DTP) outputs,
the aspect ratio of the video can be controlled by selecting a fill mode, which provides
a full screen output, or a follow mode, which preserves the original aspect ratio of the
input signal.
