Description

The Hotone Ampero II Stage MP-380 is Hotone's flagship floorboard processor, and as of firmware V1.7.0 it is the first Hotone device that natively loads NAM A2 amp captures right on the unit.

Which Ampero II processor should you choose?

Model Screen Built-in EXP pedal Mic input Balanced outs MIDI Weight NAM A2 (device)
Ampero II Stage (MP-380) 5" 800x480 touch No XLR/TS combo, 52dB, 48V phantom 2 x XLR 3.5mm TRS in/out + Bluetooth MIDI 1895 g Yes, firmware V1.7.0 (2026-07-22)
Ampero II Stomp (MP-300) 4" 800x480 touch No No XLR – 2x TS inputs 2 x TRS balanced 5-pin MIDI in/out 1050 g Yes, firmware V2.5.0 (2026-07-30)
Ampero II (MP-350) 5" 800x480 touch Yes, two-status switching XLR/TS combo, 52dB, 48V phantom 2 x XLR 5-pin MIDI in/out 1695 g Yes, firmware V1.4.0 (2026-07-30)

All three run the same 460+ effect library, 12 simultaneous effect slots, and 300 patches, and as of their current firmware, all three natively load NAM A2 files in Lite format via an onboard NAM module – Hotone's own release notes require Ampero II software V1.4.0 or later for the update. Pick Ampero II Stomp for the smallest, lightest, lowest-power board-mount unit with 5-pin MIDI and TRS balanced outs. Pick Ampero II Stage when you need XLR outs, a mic input with phantom power, two EXP/CTRL jacks, and Bluetooth, and can accommodate 1895 g and 3.5 mm TRS MIDI jacks. Pick Ampero II when you want the same XLR I/O and mic input plus an onboard expression pedal and standard 5-pin MIDI, at 1695 g.

Why guitarists choose the Ampero II Stage

  • Native NAM A2 support on the device itself: firmware V1.7.0 (released 2026-07-22) added a NAM effect module that natively loads NAM A2 files in Lite format – the first Hotone product to get this, requiring Ampero II software V1.4.0 or later.
  • 460+ effects across 16 effect modules with 12 simultaneous slots and 300 patches give you room to build full-song presets without running out of routing options.
  • Full XLR I/O: two balanced XLR outputs with ground lift plus an XLR/TS combo mic input with a 52 dB preamp and 48 V phantom power, so you can run vocals or an acoustic mic through the same unit.
  • Two EXP/CTRL jacks are officially documented as "Perfect for Ampero II Press", and the Ampero II Press manual's own wiring diagram confirms both jacks feeding this exact unit.
  • Bluetooth 4.2 dual-mode with Bluetooth MIDI lets you pair Ampero Control wirelessly by holding footswitch 2+3 on the controller, no MIDI cable required.
  • 5" 800x480 touchscreen is the largest in the Ampero II line, giving you the clearest on-stage view of patches and routing.

Controls and switches

  • 5" touchscreen – full patch/effect editing on the unit.
  • Footswitch array – patch change, effect on/off, tap tempo.
  • Power switch and input-mode selectors – INPUT L (3 modes), XLR/TS combo Input R (5 modes).
  • Mic preamp control – up to 52 dB gain with 48V phantom power for the XLR input.
  • Ground-lift switch – on the XLR outputs, to eliminate hum from ground loops.
  • 2 x EXP/CTRL jacks – for expression pedals or momentary footswitches.

Power and pedalboard compatibility

Runs on 9-18V DC centre negative, drawing up to 1.4 A at 9V; Hotone's manual recommends always using the included genuine power adapter. Input impedance is E.GT 1 MΩ / A.GT 4.7 MΩ / LINE 10 kΩ, with XLR input at 5 kΩ and FX loop return at 100 kΩ. Outputs are 1 kΩ (unbalanced, balanced, and FX send), with headphones at 47 Ω.

FAQ

Does Ampero II Stage really load NAM A2 files on the device itself? Yes. Firmware V1.7.0, released 2026-07-22, added a NAM effect module documented by Hotone as natively loading NAM A2 files in Lite format directly on the unit – the first Hotone product to get on-device NAM A2 support.

What software do I need to update to get NAM A2? Ampero II software V1.4.0 or later; the current matching editor build is Ampero II Setup V1.5.1, and Ampero II Stage Mobile V1.2.2 also added NAM A2 support in the CLONE module.

What is the difference between Ampero II Stage and Ampero II Stomp? Stage has a larger 5" screen, XLR I/O with a mic preamp and phantom power, two EXP/CTRL jacks, and Bluetooth, at 1895 g. Stomp is the smaller, lighter (1050 g) board-mount unit with 5-pin MIDI and TRS balanced outputs instead of XLR.

Does Ampero II Stage have a built-in expression pedal? No. Use the two EXP/CTRL jacks with an external expression pedal such as Ampero II Press, which Hotone's own manual names as the perfect match for this unit.

Can I control Ampero II Stage wirelessly? Yes, it supports Bluetooth 4.2 dual-mode with Bluetooth MIDI, and pairs with Ampero Control by holding footswitch 2+3 on the controller and selecting it in Stage's Search Device menu.

What power supply does it need? 9-18V DC centre negative, drawing up to 1.4A at 9V. Hotone recommends always using the included genuine power adapter.
