Connect your guitar or pedalboard output here.
The power switch has three positions. Ois off. No power is applied.Amps are muted
at their inputs, amp outputs are connected to a load and loops are put in bypass mode.
In the position, amps are muted but power is still applied to the device. In the third
position , all front panel controls are fully operational.
The LED indicator lights up when power is applied in positions 2 and 3.
If your amp is equipped with an FX loop, you can engage it by placing the switch in the
up position. This will route any FX connected to the FX INPUT and FX OUTPUT to
the corresponding Send / Return jacks on your amp. To bypass your connected FX,
place the switch in the down position.
Rotate to select the desired amplifier. The INPUT jack on the front panel will be
connected to the corresponding AMP INPUT jack on the rear panel. The AMP OUTPUT
jack will be connected to the selected SPEAKER or the ATTENUATOR if it is active. All
unused amps are muted at their inputs, switched to protection loads and their fx loops
are put in bypass mode.
Flip up to bring the connected attenuator in circuit. Use the down position to bypass
the attenuator or if no attenuator is connected to the switch. Your amps will be protected
should you not have an attenuator connected and place the switch in the active position.
Rotate to the select the desired speaker cabinet.
In most cases, this switch should be in the down position. However, should you
experience any noise that might be a grounding issue, place the switch in the up
position. For the GROUND switch to function, the amp must be connected at both the
AMP INPUT and AMP OUTPUT jacks.

Connect to the speaker output jacks of your amplifiers.
Should you experience switching noise when FX are connected to the FX INPUT
and FX OUTPUT jacks and active, find the ground position that is the quietest
with your power supply and FX. NOTE: this switch is disabled when in FX are
bypassed with the FX LOOP switch. Use the front panel GROUND switch in that
case for grounding issues.
Use only 9VDC center-negative power supplies. The switch draws between
110mA and 250mA depending on the settings. Should you hear any “whining” or
see dimming of the LED when functions are switched, the power supply is not
able to deliver enough current for the 8x6 Pro to function properly. We suggest
a 300mA or higher power supply.
Connect to the input jacks of your amplifiers. AMP INPUT 1 must be connected
to a properly ground amplifer to eliminate noise.

use this device as a load box. Always be sure to have a proper load connected
whether it is a speaker, load box or attenuator with a built-in load.

leave cables unsupported on the back of the device.
place the device near large magnetic fields such as power transformers. Doing so
may induce a voltage in the isolation transformers which will be heard as hum.
use improper cables. Be sure to use instrument cable for all AMP INPUT, FX INPUT,

PRECAUTIONS
INITIAL SETUP PROCEDURE
We recommend starting with one amp and checking your progress. With so many
cables, it can be easy to connect things incorrectly.
Be sure all devices are powered off before making any connections. Place the front
panel FX LOOP andATTENUATOR switches in the down position.
Connect a speaker cabinet to SPEAKER 1
Connect an amplifier’s speaker output toAMP OUTPUT 1.
Connect the same amplifier’s input jack toAMP INPUT 1.
If equipped, connect the same amplifier’s FX send jack to theAMP 1 SEND jack and
its FX return jack to the AMP 1 RETURN jack.
Connect the input of your pedalboard or FX unit to the FX INPUT jack and its output
to the FX OUTPUT jack. Note: FX will be bypassed while the front panel FX LOOP
switch is in the down position.
If you have an attenuator, connect its input to the ATTENUATOR INPUT jack and
its output to the ATTENUATOR OUTPUT jack. Note: the attenuator will be bypassed
while the front panel ATTENUATOR switch is in the down position.
Connect your guitar to the front panel INPUT jack. Rotate theAMPLIFIER dial to
position 1. Rotate the SPEAKER dial to position 1.
Power on the 8x6 Pro and then turn on your amplifier.
Listen for the guitar signal. If you hear it coming from the speaker, move on to 12. If
not, double check your cable connections as well as the amplifier and guitar volume
controls. Should you hear ground noise, you may need to move this amp to another
position or place the front panel GROUND switch in the up position.
To test your FX connections, place the FX LOOP switch in the up position. Should the
sound disappear, check your cable connections as well as the FX output level. Should
you hear excessive noise when switching the FX LOOP on or off, try switching the
rear panel GND switch to find the quietest position.
To test your attenuator, place the ATTENUATOR switch in the up position. Should the
sound disappear, check your cable connections as well as the attenuator output level.
Repeat the above steps as necessary to add the rest of your amps and cabinets.
