Main Features
• Lightweight, Compact, and Energy-Efficient
Employing the latest developments in high-efficiency amplifier technology, the SRA-200E packs a powerful 100 watts per channel (at 8
ohms); yet it weighs a mere 5.0 kilograms, consumes only half the current, and generates just one-third the heat of previous power
amps (in actual operation, compared with previous Roland products). With its compact design, this amp takes up only 1U (1.75-inch
EIA standard rack space), and is only 360 mm deep.
• Packed with Features
The SRA-200E features three types of input connectors: XLR-3-31 connectors, standard phone TRS jacks, and screw type terminals.
All inputs are balanced. With the Input Level switch, input sensitivity can be switched between +4 dBm and -10 dBm, flexibility that
ensures compatibility with a variety of systems. The SRA-200E also features binding post output terminals which can accept either
banana plugs or wide-gauge speaker cables.
• Protection Circuits for Added Reliability
The SRA-200 features a variety of protection circuits, including the PC Limiter Circuit that guards against shorting in the output, the
Thermal Protection Circuit, the speaker-saving DC Detection Circuit, the Muting Circuit that cuts the "shock noise" that occurs when
the power is switched on, all to ensure dependable operation.
• The indicators let you know about signal conditions.
With the LEVEL indicator and PROTECTION indicator, you can check to be sure of the amp's operating conditions.
• Built-In Limiter
The SRA-200 features an internal Limiter Circuit. This provide protection against unpleasant sound and damage to speakers resulting
from clipping in the amp.
New ECOS High-Efficiency Amplifier Technology
ECOS (Efficiency Control Operation System) is a new high-efficiency amplifier technology developed by Roland. With this technology,
amplifier power consumption is only 1/2 that of previous amps, while generating only 1/3 of the heat, all with no sacrifice in sound quali-
ty. As a result, the heat dissipation and power sections are smaller, making the amplifier lighter and more compact than previous mod-
els.
