Dual Mono Class D Amplifier 2x TPA3118D2 2x60W 4 Ohm
Allo proposes a new version of its amplifier Volt Amp with this Volt+D. This one takes the big concepts of its big brother but presents itself this time as a double mono amplifier, in Class D.
The Allo Volt+ D amplifier is a delightful surprise. Careful design has elevated the performance of these switching "chip amplifiers" to that of mass market hifi/class AB designs. Yet, it runs cool and costs very little. Yes, you need an external power supply and that is the only flaw I see with going with this solution.
At the heart of this amplifier are two TI TPA3118D2 amplification chips, one chip per channel, allowing 2x60W to be developed. All capacitors in the audio stage have also been replaced by more powerful film capacitors. The power supply has also been improved as well as the inductance of the output stage. Also note the presence of a volume attenuator with relay switching, normally not found on a device at this price.
In addition, it becomes possible to select the gain (20 or 26) via a switch at the rear of the device, but also to adjust the AM bandwidth avoidance circuit.
In the end, this Volt+D allows you to enjoy more power while having a lower THD+N than the Volt Amp. In addition, the unit now directly includes a volume attenuator, allowing quick and easy operation of the amplifier.
The power of the amplifier depends on the voltage supplied by the power supply. Generally, the rule is V² / R. So for 23V we will have about 60W per channel.
