ACOUSTIC RADIATOR 1 & 2

ACOUSTIC RADIATOR (RESO) 1

INPUT

The Acoustic Radiator 1 is a twin channel unit. Channel 1 is for Active or Piezo inputs,

while Channel 2 works for Low Z or Microphone inputs on either jack or XLR.The

two channels allow both mic and pick-up inputs to be mixed together to give the best

possible sound for the acoustic guitar. Alternatively one channel can be used for the

guitar and the other for a vocal mic to form a mini PA system.

ACTIVE / PIEZO SWITCH

The Active / Piezo switch allows channel 1 input to be set for active guitars (those with

a built-in preamp) or passive / piezo instruments where a higher input level and

impedance would be required.

PHANTOM POWER SWITCH

This can be switched in to apply a Phantom Power voltage to channel 2 inputs.This is

only for use with suitable capacitor microphones. Do not switch this in for any other

type of input to channel 2.

INPUT LEVEL CONTROL / LED LEVEL INDICATOR

Once you have set your instrument to the required Eq settings on both the amplifier

and the instrument you should then set the INPUT LEVEL to the most efficient level to

optimise signal to noise ratio.The optimum level is when the input level LED is

indicating GREEN most of the time for normal playing, with occasional peaks flashing

RED.The LED indicates the level for both channel 1 and channel 2.

PHASE SWITCH IN / OUT

This switch reverses the Phase of the signal through the amplifier and is used to help

eliminate standing wave feedback. As such it is very dependent upon the position of the

player relative to the amplifier. If feedback is occurring try altering the setting of this

switch to cancel out the standing wave between you and the amplifier.

SHAPE IN / OUT

This switch introduces a natural pre-shape to the sound of channel 1 adding a bass boost, a mid cut and a

treble boost that suits both strumming and finger picking styles of playing.

Eq - TREBLE & BASS

These controls can boost or cut the amount of Treble and Bass of the unit. In their centre position (12

o'clock) they have no effect i.e. the Eq is flat.

NOTCH FREQUENCY

The Acoustic Radiator 1 has a single Notch filter applied to channel 1.This can be switched in and adjusted

to eliminate 'body resonance' feedback of the instrument at higher playing levels. Adjust the Notch

Frequency until the body resonance reduces - this will be the optimum position for the instrument.This

Notch has a fixed 'Q' that has been optimised for acoustic guitar.

REVERB

Reverb can be added to the sound of the acoustic instrument to make it sound more vibrant and alive. It

simulates the sound of the instrument being played in various acoustic environments.The level of reverb to

direct sound can be adjusted using the Level control. Switches have been provided to select between Long

and Short decay characteristics of both Hall and Plate reverbs.The reverb is situated after the Effects

Return and as such can be added to other effects connected via these sockets.When switched in, reverb is

added to both channel 1 and 2.

OUTPUT

This sets the desired playing level/volume of the amplifier.

ACOUSTIC RADIATOR (RESO) 2

INPUTS

The Acoustic Radiator 2 is a twin channel unit. Channel 1 is for Active or Piezo inputs, while Channel 2

works for Low Z or Microphone inputs on either jack or XLR.The two channels allow both mic and pick-

up inputs to be mixed together to give the best possible sound for the acoustic guitar. Alternatively one

channel can be used for the guitar and the other for a vocal mic to form a mini PA system.

ACTIVE / PIEZO INPUTS (CHANNEL 1)

Channel 1 has two input jack sockets, one for active guitars (those with a built-in preamp) and the other

for passive / piezo instruments where a higher input level and impedance is required.

PHANTOM

POWER

The Acoustic Radiator 2 features identical 5 band Eq for both channels, the large rotary controls for Bass,

Middle and Treble allow you to set with ease the sound you require. Use the smaller controls between

these to fine tune your mid frequencies. All controls in this section can either boost or cut the signal at

their centre frequencies. In their centre position (12 o'clock) they have no effect i.e. the Eq is flat.

SHAPE SWITCH

This switch introduces a natural pre-shape to the sound of either channel 1 or channel 2, adding a bass

boost, a mid cut and a treble boost that suits both strumming and finger picking styles of playing.

NOTCH FREQUENCY

The Acoustic Radiator 2 has two separate Notch filters, one on each channel.These can be switched in and

adjusted to eliminate 'body resonance' feedback of the instrument at higher playing levels. Adjust the Notch

Frequency until the body resonance reduces, this will be the optimum position for the instrument.This

Notch has a fixed 'Q' that has been optimised for acoustic guitar.

REVERB

To make the sound more vibrant and alive Reverb can be added to either channel.This simulates the sound

of the instrument being played in various acoustic environments.The level of reverb to direct sound can be

adjusted using the Level control. Switches have been provided to select the reverb for channel 1, channel 2

or both.This feature is also foot switchable using any latching foot switch plugged into the Reverb Mute

rear panel jack socket.

EFFECTS TYPE

This allows you to select one of 16 digital effects to be added to channel 1 or channel 2. Available types

are: Hall 1, Hall 2, Room 1, Room 2, Room 3, Plate 1, Plate 2, Spring, Delay Short 1, Delay Short 2, Delay

Short 3, Delay Short 4, Delay Long 1, Delay Long 2, Delay Long 3, Delay Long 4.

OUTPUT

This sets the desired playing level / volume of the amplifier.

OUTPUT MUTE

This facility is also foot switchable. It will mute the output to the internal speakers as well as the D.I.

output.This will allow you to tune your instrument whilst the amplification is muted with a tuner plugged

into the Line Out socket, which is not muted during this operation.
