Eversolo AMP-F2 Power Amplifier
800,00 €
The Eversolo AMP-F2 is a two-channel Class D power amplifier for stereo or mono audio systems. It delivers 250 W RMS per channel into 4 Ω at 1% THD. XLR and RCA inputs accommodate different analogue sources. According to the seller, the SAPS power supply reduces noise and helps reproduce dynamic changes accurately. In bridged mode, both channels are combined to power one speaker.
The Eversolo AMP-F2 amplifier is a two-channel Class D power amplifier designed for a stereo system with a preamplifier or variable-level source. It delivers 250 W RMS per channel into 4 Ω at 1% THD. Bridged mode allows the unit to operate as a mono power amplifier.
NS600 Module and Power Supply
This model was developed through collaboration between the Eversolo and Starke Sound teams. It is based on the NS600 Class D amplifier module, which uses PurePath Ultra-HD technology. Its advanced feedback design incorporates error correction.
According to the seller, signal processing operates at a sampling rate of up to 600 kHz. The dedicated 600 W SAPS switch-mode power supply features low ripple and low electromagnetic interference. According to the seller, the SAPS design reduces noise and helps reproduce dynamic changes more accurately.
Analogue Connections and System Control
The two-channel balanced XLR input is intended for a preamplifier or source equipped with XLR outputs. A balanced connection helps reduce the risk of interference picked up by the cable. The two-channel unbalanced RCA input accommodates standard analogue RCA outputs.
Volume is controlled through the connected preamplifier or a compatible player with preamplifier functionality. Suitable partners include Eversolo network players that provide this function.
5-12 V trigger input and output connections use 3.5 mm jacks. They allow an automatic power-on chain to be created with compatible system components. Speakers connect to two pairs of beryllium-copper binding posts custom-made by Starke Sound.
Stereo and Bridged Modes
In stereo mode, the amplifier drives two separate channels. In bridged mode, both channels are combined to power one speaker. This configuration delivers 450 W RMS into a 2 Ω load.
The stated bridged-mode power rating should not be applied to other impedances. Maximum output current is 16.5 A per channel or 33 A in bridged mode. Using two amplifiers makes it possible to build a stereo system with a separate mono power amplifier for each channel.
Positioning in an Equipment System
At 270 mm wide, the enclosure does not occupy the full width of a standard equipment shelf. Its 228 mm depth requires additional clearance for the rear XLR, RCA and speaker connections. Do not cover the enclosure, and leave space for air circulation.
Power consumption is below 0.5 W in standby. When switched on without an input signal, the amplifier consumes 14 W. The trigger connections help automate switching between operating and standby modes.

FAQ
Does this power amplifier require a preamplifier?
Yes. The system needs a device that controls volume and supplies an analogue signal. This can be a preamplifier or a player with a variable-level output.
When should I choose XLR rather than RCA?
Choose XLR when the source has balanced outputs or when longer analogue cables are used. RCA is suitable for sources that provide only unbalanced analogue outputs.
Is one amplifier enough for a stereo system?
Yes. One unit can power the left and right channels. Two units are required only when using a separate mono amplifier for each channel.
What should I know before selecting bridged mode?
This mode is intended to power one speaker, and the stated output applies to a 2 Ω load. Switch off the amplifier and all connected components before changing the configuration.
How should I plan the space on an equipment shelf?
Allow for both the enclosure depth and the extra space required by connectors and cables. Leave uncovered space above the amplifier to support air circulation.
