VENTILATOR QUICK START GUIDE

1 Speed – adjusts the rotation speed of the effect.

This control affects both rotors equally. 12:00

mimics the speed of a well maintained Leslie® 122.

2 Acceleration – increases or decreases the time

necessary to fully change speeds. This control

affects both rotors equally. 12:00 mimics the lag of

a well maintained Leslie 122 with new belts.

3 Balance – affects the ‘virtual mic’ balance between

the upper and lower rotors. Turning right increases

the treble rotor’s prominence; left increases the bass

rotor’s prominence. 12:00 sets equal balance

4 Drive – changes the gain or ‘growl’ of the amplifier.

All the way to the left provides no overdrive effect.

As the knob is moved to the right, the level of growl

increases. Think of this as equivalent to the volume

control on the Leslie power amp.

5 Distance – changes the distance between the

vertical mics and the rotors. All the way to the left

mimics placing the mics extremely close to the

rotors – probably closer than practical in a real

Leslie. All the way to the right mimics placing the

mics 1-2 feet from the Leslie. 12:00 mimics the

sound of typical mic placement (3-4 inches away).

6 Overload LED – this indicator should only come on

occasionally during performance. If it comes on

steadily or very often, turn down the level of the

input source (keyboard or guitar).

7 Slow/Fast – this switch controls the speed of

rotation. In Leslie parlance, Slow is equivalent to

‘Chorale,’ and Fast is equivalent to ‘Tremolo.’

8 Lo LED – this indicator is synchronized to the

current speed of the lower (bass) rotor.

9 Hi LED – this indicator is synchronized to the current speed of the upper (treble) rotor. When the LED is brightest, the rotor is

pointed at the virtual mic.

10 Bypass – this switch bypasses the entire rotary effect, amp simulation, and cabinet simulation. The Ventilator provides true

(switched) bypass.

11 Bypass LED – lit when the Bypass function is selected.

12 In – connect to the instrument’s output(s).

13 Out L – connect to the left side of the amplifier system.

14 Out R/Mono – connect to the right side of the amplifier system.

15 Remote – to be connected to a remote footswitch.

16 Lo/Hi – this gain switch selects a +4dB or -10dB nominal range for both input and output.

17 Key/Guit – this switch selects whether the cabinet simulation is active (Key) or bypassed (Guit).

18 12V DC – connect to an approved DC power source with positive center connection. Use of unapproved power sources may

cause excessive hum and distortion, and possibly damage the Ventilator.

STANDARD VENTILATOR (WITH OR WITHOUT THE ST BARKER MOD):

  

This is how the

Ventilator connects in

a typical all-mono

setup, with a mono

sound source, and a

mono amplification

system.

  

This is how the

Vent is connected

in a stereo system.

The input is still

mono, so the Vent

will not produce a

stereo effect when

in Bypass; instead,

both sides will

receive the same

mono signal.

STEREO MOD VENTILATOR (WITH OR WITHOUT THE ST BARKER MOD):

  

The Stereo Mod

Ventilator can still be

used in a full mono

setup. Note that the

output jack is plugged

into the Out L jack.

  

This is how the Stereo

Mod Ventilator is

connected in a full

stereo setup, using a

Y cable for separate

left+right inputs. Full

stereo will be

maintained in Bypass.

REMOTE FOOTSWITCH PEDAL:

Whether the Ventilator is used in mono or stereo, a remote footswitch can be added.

To control the rotating speed. This switch works in parallel with the Ventilator’s

onboard Speed switch. If either of the switches is set to Tremolo (fast) speed, the

Ventilator will switch to Fast. If both of the switches are set to Chorale (slow) speed,

the Ventilator will switch to Slow.

The remote switch can also select Stop or Off. This simulates a Leslie whose motors

have been turned off. In this mode, the amplifier simulation in the Ventilator is still

active. Thus, the result is different than when pressing Bypass.

The Ventilator is compatible with foot and ‘halfmoon’ switches from NEO Instruments,

Ashby Solutions, Clavia (Nord), and Hammond-Suzuki. See the Ventilator owner’s

manual for more details. It is not compatible with most sustain, tremolo-reverb,

channel-boost, or other switches used with other musical gear.

Note that the footswitch cable has a TRS plug.
