To Next PageTo Next PageWhy Ssl Amplifier will not power up?
If your Ssl Amplifier isn't powering up, ensure you have a solid ground connection and that the Remote Input (Turn-On) receives at least 3VDC. Verify battery power at the (+) terminal, ensuring at least 12V is present. Inspect all fuses, replacing any that are faulty. Finally, check that the Protection LED is off; if it's on, briefly power cycle the amplifier.
What to do if Ssl Amplifier gets very hot?
If your Ssl Amplifier is overheating, verify that the speaker impedance matches the amp model's minimum requirement. Ensure adequate air circulation around the amplifier. Consider adding an external cooling fan if necessary for your setup.
Why Ssl EV2.200 has distorted sound?
If you're experiencing distorted sound from your Ssl Amplifier, first ensure the Input Level Control is appropriately set for your head unit's signal level, keeping it as low as possible. Also, check that all crossover frequencies are correctly configured and inspect speaker leads for any short circuits.
What to do if Ssl EV2.200 protection LED comes on?
If the Protection LED on your Ssl Amplifier illuminates upon powering up, check speaker leads for short circuits. Reduce the head unit's volume to prevent overdriving. Disconnect the speaker leads and reset the amplifier. If the Protection LED remains on, the amplifier may be defective and require servicing.
How to fix engine noise (alternator whine) in Ssl Amplifier?
To address alternator whine in your Ssl Amplifier, check that speaker leads and RCA grounds are not shorted to the vehicle chassis. Also, ensure the head unit is properly grounded.
How to fix engine noise (static type) in Ssl EV2.200 Amplifier?
Engine noise (static type) in your Ssl Amplifier setup is often due to low-quality RCA cables picking up radiated noise. Try using high-quality cables and route them away from power cables.
Why Ssl EV2.200 Amplifier has no output?
If your Ssl Amplifier has no output, first check that all fuses are in working order and that the amplifier is properly grounded. Next, verify that the Remote Input (Turn-On) is receiving at least 3VDC, that the RCA audio cables are correctly connected to the inputs, and that all speaker wiring is properly connected.
How to eliminate high hiss in the Ssl Amplifier speakers?
To reduce hiss in your Ssl Amplifier speakers, disconnect all RCA inputs to the amplifiers. If the hiss disappears, plug in the component driving the amplifier and unplug its inputs. Repeat until you find the faulty component. Set the amplifier's input level control as low as possible. Maximize the head unit volume (without distortion) and minimize the amp input level.
Why Ssl EV2.200 audio present in only one channel?
If audio is only present in one channel of your Ssl Amplifier, check the RCA interconnect cables and all speaker wiring.
How to fix squealing noise from Ssl Amplifier speakers?
To address squealing noises from your Ssl Amplifier speakers, check for improperly grounded RCA interconnects.
The Sound Storm Laboratories EVOLUTION series introduces two new high-power car audio amplifier models, the EV2.200 (2-channel) and the EV4.400 (4-channel), both designed in the USA. These amplifiers are engineered to deliver a high level of performance and quality, ensuring years of listening pleasure for car audio enthusiasts.
The EVOLUTION amplifiers are designed to boost the audio signal from your car's head unit or signal processor, driving speakers with increased power and clarity. The EV2.200 is a 2-channel amplifier, suitable for powering a pair of speakers or a single subwoofer in bridged mode. The EV4.400 is a 4-channel amplifier, offering more flexibility for multi-speaker setups, such as powering front and rear speakers, or a combination of speakers and subwoofers.
Both models feature built-in fixed crossovers to optimize sound delivery to your speakers. The EV2.200 includes a fixed low-pass crossover set at 120Hz, ideal for subwoofer applications. The EV4.400 provides a fixed low-pass crossover at 120Hz for channels 3/4, and a fixed high-pass crossover at 200Hz for channels 1/2. This allows for precise frequency distribution, ensuring that each speaker receives the appropriate range of sound, which helps prevent distortion and improves overall audio quality.
The amplifiers are designed for 2 Ohm stable stereo operation, meaning they can efficiently handle speaker loads down to 2 Ohms. This capability allows for greater flexibility in speaker configurations, such as connecting multiple 8 Ohm speakers per channel using parallel wiring, which can significantly increase output power. Operating at 2 Ohms can boost the amplifier's output power by approximately 50%, although it also increases current draw, so adequate current supply is crucial to avoid distorted music reproduction.
The EVOLUTION amplifiers offer versatile input options, featuring both high-level and RCA low-level inputs on the front panel. Low-level (RCA) input wiring is preferred for optimal audio performance, and users are advised to use high-quality RCA cables. High-level inputs should only be utilized when the head unit lacks RCA outputs. It is crucial not to connect both high-level and low-level inputs from the receiver to the amplifier simultaneously to prevent damage and ensure proper operation.
Input level can be precisely controlled by variable input gain controls. These controls are designed to match the output level of your audio source to the input level of the amplifier, not to act as a volume control. It is recommended to set the input level as low as possible while still achieving the desired output, to prevent input overload and excessive audio distortion, which could also trigger the protection circuit.
The amplifiers incorporate a remote turn-on/turn-off circuit, allowing them to power on and off in sync with your head unit, simplifying system integration. LED power and protection indicators provide visual feedback on the amplifier's status, alerting users to potential issues such as short circuits or overheating.
The EVOLUTION amplifiers are built with several features to ensure reliability and ease of maintenance. They include thermal and speaker short protection, which safeguard the amplifier and connected speakers from damage due to excessive heat or electrical shorts. A soft turn-on circuit prevents abrupt power surges when the amplifier is activated, extending its lifespan and protecting other audio components.
The black anodized heatsink efficiently dissipates heat, contributing to stable operation and preventing thermal overload. In some applications, if the amplifier consistently runs very hot, adding an external cooling fan may be necessary to ensure optimal performance and longevity.
For troubleshooting, the manual provides comprehensive guidance on common issues such as the amplifier not powering up, the protection LED coming on, no output, low output, audio present in only one channel, high hiss, squealing noise, distorted sound, the amplifier getting very hot, and engine noise (static or alternator whine). These tips help users identify and resolve problems by checking connections, fuse status, ground connections, input levels, crossover settings, and speaker wiring.
In case of a blown power fuse, it is critical to replace it only with a fuse identical to that supplied with the amplifier. Using a fuse of a different type or rating can lead to damage to the audio system or the amplifier, which would not be covered by the manufacturer's warranty.
Users are strongly advised against opening the case of the product or attempting repairs themselves, as dangerous high voltages are present within the unit, and there are no user-serviceable parts. All repairs should be referred to a qualified service technician. Additionally, to prevent electronic shock or damage, the amplifier should not be exposed to dampness or wetness from water or drinks. If such an incident occurs, the power wires should be immediately unplugged, and the amplifier sent to a local dealer or service center. Similarly, if smoke or a peculiar odor is detected, or if there is damage to any component enclosures, the power cord should be unplugged immediately, and the amplifier serviced.
