- the product has been dropped or the cabinet has been damaged,
- the product does not operate normally.
• Exposure to extremely high noise levels may cause permanent hearing
loss.
• Individuals vary considerably in susceptibility to noise induced hear-
ing loss, but nearly everyone will lose some
hearing if exposed to sufficiently intense noise for a sufficient time.
The U.S. Government´s Occupational Safety and Health Administration
(OSHA) has specified the following permissible noise level exposures:
DURATION PER DAY IN HOURS SOUND LEVEL DBA, SLOW RESPONSE
8 90
6 92
4 95
3 97
2 100
1.5 102
1 105
0.5 110
0.25 or less 115

• According to OSHA, any exposure in excess of the above permissible lim-
its could result in some hearing loss.
• Ear plug protectors in the ear canals or over the ears must be worn
when operating this amplification system in order to prevent a permanent
hearing loss if exposure is in excess of the limits as set forth above.
To ensure against potentially dangerous exposure to high sound pressure
levels, it is recommended that all persons exposed to equipment capable
of producing high sound pressure levels such as this amplification system
be protected by hearing protectors while this unit is in operation.
WARNING
TO REDUCE THE RISK OF FIRE AND SHOCK HAZARD, DO NOT EXPOSE THIS PRODUCT
TO MOISTURE OR RAIN.
DO NOT OPEN CASE; NO USER SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

1) CONNECTING THE CABINET TO YOUR AMP
Depending on the type of cabinet, there are a range of options as far
connections are concerned. It is important for safe operation that these
options are understood. If in doubt, please contact us under info@palmer-
germany.com.
1.1) 1X10 / 1X12 CABINETS
The below picture shows the jackplate for the 110 and 112 cabinets.

You may use either of the sockets as an input.
NOTE
Never use both sockets as inputs (i.e. do not connect two amps or speaker
outputs to this cabinet). This can damage the amplifier(s) and speaker.
CONNECTING A SECOND CABINET
The two sockets are wired in parallel. This means you can connect a sec-
ond cabinet to this cabinet. When connecting a second cabinet, make sure
the impedances of both cabinets are Identical. Because the sockets are
wired in parallel, the resulting impedance will be halved.
Example: The first Palmer cabinet has an impedance of 8 Ohms. The Second
cabinet must also have an overall impedance of 8 Ohms. Connect the second
cabinet to one of the sockets of the first cabinet. The overall impedance
that the amp now “sees” is 4 Ohms.
NOTE
Ideally the power handling of both cabinets should be similar. If the
power handling of the cabinets is similar or the same, then you can add
them. I.e. Two cabinets with a power handling of 75W each can handle 150W
when linked together.

1.2) 2X12 CABINETS
The below picture shows the jackplate for the 212 cabinets.

1.2.1) MONO AND STEREO MODE
TO RUN THE CABINET IN MONO MODE
Connect the speaker out of your amplifier to the socket marked “Left/
Mono”. In this case both speakers are wired in parallel and both will
sound.
Example: If the cabinet is loaded with two 16 Ohms speakers, then the
total impedance at the “Left/Mono” socket will be 8 Ohms.
TO RUN THE CABINET IN STEREO MODE
First connect the socket marked “Right”. As soon as a jack connector
is plugged into this socket, the connection between the two speakers
is broken. The cabinet can now be used like two individual 112 cabi-
nets. The signal/amp connected to the “Right” socket will feed the right
speaker and the signal/amp connected to the “Left/mono” socket will feed
the left speaker.
NOTE
Switching between the modes Mono and Stereo is done via a switching jack
socket used for the “Right” input – plugging a jack connector to this
socket will switch the cabinet into stereo mode.
When in Stereo mode, each speaker runs individually. If your cabinet is
loaded with 16 Ohms speakers, then you will have 2x 16 Ohms inputs.

1.3) 4X12 CABINET
The below picture shows the jackplate for the 412 cabinets.
Since the 412 cabinet consists of four speakers you have more options as
far as connections are concerned.

13

ES FR
1.3.1) MONO AND STEREO MODE
Use the slide switcher to switch between the two modes.
NOTE
Never switch while you are playing. In most cases changing the mode of
the cabinet will also require you to change connections on the amp or ca-
binet. Switch your amp to standby or turn it off before you operate this
switch.
Mono Mode: When in Mono mode you can use one of either sockets as an in-
put. In Mono Mode never use both sockets simultaneously.
As you may notice, each socket is labeled with a different impedance (in
most cases 4 Ohms and 16 Ohms).
Stereo Mode: When the cabinet is switched to Stereo mode each of the two
sockets is responsible for the corresponding side. If the cabinet is
loaded with 16 Ohms speakers then each side will have an overall imped-
ance of 8 Ohms.
To understand the background/nature of this, please see the below ex-
ample:
Background example: The 412 cabinet is loaded with four 16 Ohms speakers.
The vertical pairs of speakers (left and right sides of the cabinet) are
each wired in parallel. That means we have a resulting/overall impedance
of 8 Ohms per side. These two sides can again be wired together, on one
socket the wiring is parallel and on the other serial – that is why you
can choose between 4 Ohms or 16 Ohms when the cabinet is in mono mode.

2) REMOVING THE GILL
For servicing or if you want to position your microphone closer the front
grill of the cabinets can be removed. The grill is fastened with Velcro
pads.
The first removal of the Grill can be a bit tough since it is firmly in-
serted during production – subsequent removals will become easier.
Pull the straps at the lower edge of the grill, pull slowly with constant
force and do not jerk. If necessary insert a screwdriver into the loop of
the strap so you can apply more force.
NOTE
When removing the grill on the 412 cabinet be sure to pull the grill off
slowly to avoid strain on the joint of the slanted front.

3) INSERTING/REPLACING SPEAKERS
To insert or replace a speaker carry out the following steps:
1Remove the grill
2Lay the cabinet down on its back on a clean padded surface (use a
blanket, carpet or similar to make sure the back of the cabinet doesn’t
get any scratches and the jackplate is not strained).
3Place the speaker on to the baffle next to the cutout – close enough
so you can connect the leads of the jackplate to the speaker.

4Carefully connect the faston connectors on the end of the cables
coming from the jackplate to the connectors of the speaker.
NOTE
Do not apply excess force here. If necessary wriggle the connector until
it slides on.
One of the wires of the cable is marked red – connect this wire to the
connector marked with a “+” on the speaker.

3.1) CONNECTING THE SPEAKERS ON A 212 CABINET
On the 212 cabinets there are two cable pairs, one pair for each speaker.
Make sure to wire both speakers the same way (red lead to “+”). Otherwise
the speakers will be out of phase and the sound will be poor.
3.2) CONNECTING SPEAKERS ON A 412 CABINET
The 412 cabinet comes with two additional short connection cables. These
are to interconnect the speakers vertically. After connecting the speak-
ers vertically (parallel connection), connect each side to the corre-
sponding cable coming from the jackplate. Please refer to the next dia-
gram.

5Place the speaker into the cutout and position the speaker so it
matches the holes in the baffle.
NOTE
Some speakers ship with padding on both sides of the basket, others only
have padding on one side. As the speakers on the Palmer cabinets are
front loaded, make sure they are padded on the back. If they are not
padded you can resort heat insulation tape as it is used for windows and
doors or similar.

6Use the supplied screws and fasten the speaker to the baffle in the
following order (1-4). Once all screws are tightened, retighten them.
NOTE
Do not over tighten the screws. Do not use a power-drill or power-
screwdriver!

IMPORTANT NOTE
The baffle is equipped with four M5 T-Nuts (drive-in-nuts)
When inserting the screws into the holes and when tightening them APPLY
MINIMAL DOWNPRESSURE!
Too much pressure on the screw will push the T-Nut out.
Tighten the screws slowly and carefully to make sure they do not cant –
the nut can jam!
TOO MUCH PRESSURE ON THE
SCREW WILL PUSH THE T-NUT OUT!
