The Flatline Acoustics FL-AP2-50W is a digital amplifier in a compact housing equipped with low temperature technology. Its output power is 2 x 50W into 4Ω and 2 x 25W into 8Ω which means it can be connected to a variety of different speakers types and brands to offer a convenient and discrete installation. The easy-fit “Phoenix” connector for the speaker terminals is suitable for cables up to 2.5mm2. The digital TosLink optical input supports a 2-channel PCM stereo signal. The line-level analog input is equipped with standard phono sockets. Both audio inputs are read simultaneously by the amplifier which means that the amplifier can accommodate two inputs to share one set of speakers. The input sensitivity is also shared for both inputs and set jointly using the level control.

Modes of Operation:
The FL-AP2-50W has 3 modes of operation:
On – The amplifier is in operation as soon as the power supply via the switch is ON.
Auto – The amplifier turns on automatically as soon as a signal is detected at either the analogue or
digital inputs. Note: The digital input is not triggered by optical light, but by sensing an actual audio signal input. The benefit of this is that the FL-AP2-50W can enter standby mode when there is an active optical connection but with no audio signal. After approximately a 10 minute period without an audio signal detected, the device will enter standby mode.
Trigger – When a voltage of 2.7V to 12V is applied to the trigger input connectors the amplifier will activate. With a voltage less than 1.5V to the trigger inputs, the FL-AP2-50W will enter standby mode.
