of the amplifiers to be switched.
FROM OUTs: Using high quality UNshielded
SPEAKER cables, connect these
jacks to the speaker output jack of the
amplifiers to be switched.
SPKR: Using a high quality UNshielded
SPEAKER cable, connect this jack to
the speaker cabinet.
FTSW: Connect the supplied footswitch to this
jack using a ¼” tip-ring-sleeve cable
(for the dual-color LED to work on the
footswitch) or a standard ¼” tip-sleeve
cable (for just the green color of the
footswitch LED to work).
POWER: See the Power Requirements section.
STATUS LED: Green = AMP #1 & Red = AMP #2
Basic Operation
HAVE YOU READ THE HEAD SWITCHER SAFETY &
WARNING DISCLAIMER ? WELL READ IT AGAIN !!!
Connect a guitar/pedal, the amplifiers, the speaker
cabinet and the footswitch to the HS2 Remote Head
Switcher as described in the Connections section
(above). It is strongly recommended that the switcher
be positioned near the heads and cabinet to minimize
the chance of a cable being accidentally disconnected.
Make sure that ALL connections to and from the HS2
Remote Head Switcher are complete and correct.
ALWAYS apply power to the HS2 Remote Head
Switcher first and verify both the front panel LED and
footswitch LED change color and that you can hear the
relays switching whenever you stomp on the footswitch
(if not, DON’T use the switcher and contact Axess for
support). Now power-up the rest of your gear and let it
rip, simply stomp on the footswitch to switch between
heads !!!

Head Switcher
•The HS2 Head Switcher allows instant
switching between two different tube amp
heads and the same speaker cabinet.
•The head switcher is remote controlled by a
single latching footswitch (included) using a
¼” tip-ring-sleeve cable (for the dual-color
LED to work on the footswitch) or a standard
¼” tip-sleeve cable (for just the green color of
the footswitch LED to work).
•The footswitch is housed in a .094” thick
black anodized aluminum enclosure (4.40" x
2.40" x 1.30") and along with the dual-color
LED it has a long-lasting, heavy-duty Carling
(the real thing) stomp switch which has a
positive tactile feel.
•Switching between the two amps is dead
quiet and immediate - no loud clicks, pops or
drop-outs.
•A proprietary circuit allows only one amp on
at a time, protects the amplifier that is not
selected and protects both amps and the HS2
relays when switching.
•Proper circuit design and isolation of the
amplifiers ensures no Ground Loop Hum or
Noise, signal/tone coloration or degradation.
•Powered by a 9VDC Adapter (like those from
Boss) with a 5.5mm/2.1mm barrel connector.
•Housed in a compact (7.50" x 3.75" x 1.50")
and rugged .064” thick aluminum enclosure
for years of reliable use and performance.
•Brushed finish with black anodize coating and
laser-engraved printing.

Head Switcher Safety & Warning
1. The Head Switcher switches high level speaker signals. Failure to properly connect it
WILL damage the amplifiers and/or the Head Switcher, so ALWAYS make sure that ALL
connections to and from the Head Switcher are complete and correct before applying
power to any piece of equipment.
2. ALWAYS match both amplifier impedance settings to the speaker cabinet connected.
3. ALWAYS use high quality shielded INSTRUMENT cable when connecting from a
guitar/pedal to the Head Switcher and from the Head Switcher to the amplifier inputs.
4. ALWAYS use high quality UNshielded SPEAKER cable when connecting from the
amplifier speaker outputs to the Head Switcher and from the Head Switcher to the
speaker cabinet.
5. ALWAYS use the recommended AC Adapter (see label on the back of the Head
Switcher or the User Manual - "Power Requirements" section).
6. NEVER use the Head Switcher to switch solid state amplifiers, it WILL damage them and
the Head Switcher.
7. The Head Switcher MUST be properly grounded, not only to provide shielding
from hum/noise, but also to prevent any SHOCK HAZARD. Since the Head
Switcher uses an isolated AC Adapter, it is connected to earth ground (AC - 3rd
Pin) via it’s connection to AMP#1. AMP #2 is isolated to prevent Ground Loop
Hum/Noise. Therefore, make sure that both amplifiers being connected to the
Head Switcher are properly grounded (have a 3rd pin on the AC Plug) and have
not been modified by having the AC Ground(s) lifted.
8. Axess Electronics accepts NO responsibility for damage or injury caused by improper
connections to and from the Head Switcher.
9. NEVER use a delay with a trail-off/slapback (or any other effect that will continue to
generate an output signal after its input has been muted) between the “TO INs” jacks on
the Head Switcher and the amplifier inputs or in the effect loop of the amplifiers, UNLESS
you can GUARANTEE that the amplifier(s) with such an effect will ONLY be deselected
when there is no trail-off/slapback being generated. Otherwise, damage to the Head
Switcher and the amplifier(s) WILL occur.
10. Axess Electronics accepts NO responsibility for damage or injury caused by the failure of
any component inside the Head Switcher or its footswitch.
11. Use of the Head Switcher implies that the user/owner agrees to all of the terms stated
within this document and waives his/her right to a liability claim against Axess Electronics
for any damage or injury caused while using the Head Switcher.
