Watts on the box, and watts in a room · review
A keyboard amplifier with a mixer built in: four quarter-inch line channels, an XLR microphone input, a dedicated monitor channel for click and guide tracks, a 12-inch woofer and metal jacks throughout.
What it amounts to The amplifier on this shelf that is also a mixing desk: four channels, an XLR input, a click channel, a headphone and a sub output, and metal jacks. It publishes neither its size nor its weight, and the product record puts it at 19 kg (41.9 lb).
One hundred watts through a custom two-way system with a 12-inch woofer. Four 1/4-inch line input channels with a master EQ, a dedicated auxiliary input on 1/8-inch and RCA, and channel 4 set up as a monitor send for click and guide tracks. An XLR microphone input. A 1/4-inch line output, a headphones output and a sub output. Metal jacks.
This is not really an amplifier with extras; it is a small mixing desk with a speaker in it, and that is the right way to read the price.
Four channels is the headline. Two keyboards, a sound module and a backing track all arrive at one box, get balanced there, and leave through one line output to the front of house. The alternative on stage is a small mixer, another power supply and three more cables. No other amplifier on this shelf has more than two channels, and four of the seven have one.
Channel 4 as a monitor send is the detail that shows who this was designed for. A click track has to reach the player and nobody else; a channel meant for it sends the metronome to the headphones rather than through the speaker into the room. Any amplifier can take a click on a line input — this one publishes a channel for it, and nothing else here does.
The XLR microphone input completes the picture: a keyboard player who sings needs one socket, not a second system.
And metal jacks. It is a small sentence about a part that is plastic on almost everything, and sockets are what fail on equipment that is packed and unpacked every week. It is the only jack material published on this shelf.
What it does not publish is how big or how heavy it is. The product record gives 19,000 g (670.2 oz) — a round figure, and therefore a shipping one, but a 12-inch woofer in a 100 W cabinet is in that region. Its own shelf-mate at a fifth of the power publishes 286 × 246 × 236 mm (11.3 × 9.69 × 9.29 in) and 4.2 kg (9.3 lb); this publishes neither, and on a box that has to go in a car it is the figure a buyer needs.
At $679.99 it is the most expensive amplifier on this shelf, and the only one over five hundred dollars. The four guitar amplifiers published here run from 10 to 25 W and from a bedroom to a small room; this is a different purchase entirely.

Because a click track has to reach the player and nobody else. Channel 4 on this amplifier is set up as a monitor send, so a metronome or a guide track goes to the headphones without going through the speaker into the room. Any amplifier can take a click on a line input; what this publishes is a channel meant for it. No other amplifier on this shelf has one, and for a keyboard player in a band it is the difference between playing to a click and shouting over one.
For a stage, effectively yes. Four quarter-inch line inputs with a master EQ, plus an aux on 1/8-inch and RCA, means two keyboards, a module and a backing track arrive at one box and leave through one line output to the front of house. The alternative is a small mixer, a power supply and three more cables. No other amplifier on this shelf has more than two channels, and four of the seven have one.
Shown because the accessory names this instrument itself.
