Hook it up

Connecting the Lotus

Speaker cable in, speaker cable out, and everything connected before the amp is switched on.

Before you start

Match the model to the amp. Use the Lotus whose impedance matches your amp's speaker output: a 2, 4, 8 or 16 Ω Lotus for a 2, 4, 8 or 16 Ω output.
Use speaker cables, never instrument (guitar) cables, from the amp to the Lotus and from the Lotus to the cab.
Connect with the amp off, or in standby. A tube amp has to see a load whenever it is on.
Leave Bypass / Run alone while the amp is running. Switch it only with the amp off or in standby.

One cab

Drawn for the 8 Ω model. On the other models the same holds with their own numbers: a 4 Ω amp output to the 4 Ω Lotus to a 4 Ω cab, and so on.

Amp off. Amp's speaker output to the Lotus Amp jack, the one with the copper ring.
The Lotus output to the cab.
Bypass / Run down, to Run. Set the toggles on the front panel.
Switch the amp on and turn it up.

Two cabs

On the 8 Ω model, two 16 Ω cabs go on the stacked pair, one in each jack. Two 8 Ω cabs use the 4 Ω jack with the center jack (2×8 Ω), as the back panel letters it.

Each model's back panel is lettered for its own loads; the back panel lists them for 2, 4, 8 and 16 Ω.

As a dummy load

The Lotus M3 can be safely used as a dummy load for direct-to-DAW, board or bench testing an amp.

Keep Bypass / Run on Run. In Bypass the Lotus passes the amp straight through to the speaker jacks, so the amp needs a speaker on them.

Power for the fan

Nothing to connect. The fan runs off your amp's own signal. If you'd rather power it separately, plug 9–18 V AC or 9–24 V DC into the EXT Power jack.
