Feinsicherung 5x20 träge (4A - MA1240a & SPA250)

The Dayton Audio SPA250DSP digitally processed plate amplifier offers an elite level of control over your entire system (i.e. subwoofer and mains). This unique amplifier allows you to fine tune your system's low frequency performance, and at the same time high pass to your mains (or satellites) protecting them from damage due to over excursion. Key Features DSP functions include: 7 PEQ bands, LPF, phase, subsonic filter, limiter, mains delay, and HPF Single-knob control panel with high-contrast LCD display and status LEDs Fast, intuitive PC-based GUI software enables full access to the DSP functions Efficient Class D output topology ensures high-impact low frequency performance Includes both balanced and unbalance line level inputs and outputs With a Dayton Audio 5 year warranty, it’s more than a guarantee, it’s a promise Dayton Audio's SPA250DSP true 250 watt digital switching plate amplifier features advanced signal processing control that every audio enthusiast wants. This power and flexibility is accessible via PC-GUI software and our innovative single-knob LCD control panel. For retrofit and enclosure designs with no amplifier cutout an optional amplifier mounting frame is available for this amplifier. Note: Windows 10 and 11 UsersMicrosoft .net Framework 3.5 is required for the SPA250-DSP software to run properly. This is not installed by default in Windows 10 or 11. 1. Power Mode: Select the either energy-saving or “always-on” power mode Auto: Amp goes into standby after no detected signal input for 20 minutes* On: Amp is always on, regardless of input signal status. * Amp will automatically turn on typically in one second or less once audio signals are resumed. 2. Analog input attenuation: Affects analog balanced and unbalanced inputs only. Normal: No attenuation. Hi: Attenuates input signal by -6dB. 3. USB Control: Used for PC-GUI communication with custom PC software included with your amp. 4. Feature Control: Single knob digital actuator with single/double-click enabled with rotary scrolling to navigate the amp’s extensive feature menu. 5. Limiter LED: Lit when Limiter is active (Red). 6. Standby/On LED: Red when amp is in energy saving “stand by” state. Green when amp is operating normally.

Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier Dayton Audio's MA1240a freestanding, twelve channel amplifier was designed for custom multi-room sound distribution. Its intelligently engineered and versatile design integrates easily into high-end whole house audio systems. We stand behind our products and our warranty is a demonstration of our commitment to quality and reliability. Key Features Robust 60 WPC output at 4 ohms, 40 WPC output at 8 ohms Independent and bus inputs enable unparalleled flexibility Bridgeable channel outputs provide additional power when needed Independent channel gain controls allow the output of each speaker to be perfectly matched Multi-stage protection circuitry for reliability and easy troubleshooting of audio system Temperature controlled cooling fans ENERGY STAR and CE EuP directive compliant, consumes less than 1/2 a watt in standby Dayton Audio MA1240a Multi-Zone 12 Channel Amplifier The high-density solution to the challenges of multi-room audio The Dayton Audio MA1240a features a Class-AB output circuit that delivers superior audiophile sound quality and stable performance. Each of your installation's zones can benefit from the MA1240a's clean audio reproduction and exceptional functionality. The MA1240a can be stacked with other audio components and includes removable ears for mounting in standard audio racks (2RU). You have to feed the machine—and it's easy! Two common or BUS inputs feed audio signals from standard line-level audio sources to any or all channels. Each of the twelve channels has its own dedicated input and independent level adjustment to provide further flexibility. By simply flipping a single switch, two channels can be bridged to increase the total power output for that zone. This is helpful when extra power is needed in certain areas. All of the convenience and system status monitoring you could need The MA1240a's manual, automatic on/off, or triggered 12V input turn-on modes facilitate easy integration into automated systems. For quick and easy troubleshooting of the system, each pair of channels or zones has a bi-color LED to indicate its operational status. Note: See setup addendum when using in-wall volume controls.
