Connecting to AMP

Depending on the type of cabinet, there is a range of options as far as connections are concerned. For advanced setups or to simulate speaker outputs, you can also use a Palmer ILM Speaker Simulation DI Box to connect your cabinets to a mixer or recording interface.

1X12 Cabinets

The picture below shows the jackplate for the 112 cabinets.

You may use either of the sockets as an input.  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 the Second Cabinet

The two sockets on the Palmer PCAB112BX & PCAB212BX Guitar Cabinets are wired in parallel. This means you can connect a second cabinet to the first. 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.

2X12 Cabinets

The picture below shows the jackplate for the 212 cabinets.

Mono & Stereo Mode

TO RUN THE CABINET IN MONO MODE

• Connect the speaker from 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 cabinets. 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.

Removing the Grill

For servicing, or if you want to position your microphone closer to the front grill, the grill on the Palmer PCAB112BX & PCAB212BX Guitar 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 inserted during production – subsequent removals will become easier. Pull the straps at the lower edge of the grill slowly and with constant force. If necessary, insert a screwdriver into the loop of the strap to apply more force.

Inserting/Replacing Speaker

To insert or replace a speaker, carry out the following steps

1. Remove the grill.
2. Lay the cabinet down on its back on a clean, padded surface (use a blanket, carpet,t or similar to make sure the back of the cabinet doesn’t get any scratches and the jackplate is not strained).
3. Place the speaker onto the baffle next to the cutout – close enough so you can connect the leads of the jackplate to the speaker.
4. Carefully connect the faston connectors on the end of the cables coming from the jackplate to the connectors of the speaker.

Connecting to 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 or marked lead to “+”). Otherwise, the speakers will be out of phase,se and the sound will be poor

• Place the speaker into the cutout and position the speaker so it matches the holes in the baffle.

Anmerkung

Some speakers ship with padding on both sides of the ba; ket, 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 to heat insulation tape, as it is used for windows and doors or similar.

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

Testing the Cabinet

To test the speakers in your Palmer PCAB112BX & PCAB212BX Guitar Cabinets, there is a simple method to check if all the speakers in a multi-speaker cabinet are in phase. All you need is a 9V battery and a speaker cable. Connect the speaker cable to the cabinet and take the jack connector at the other end, and let it touch the poles of a 9V Battery (one pole on the tip and the other on the sleeve of the jack connector).

This will result in a Plo,p, and the speakers will move either inwards or outwards, depending on which way you connect the battery. Speakers must move in the same direction. If they don’t, then you know that they are out of phase (check that the wiring on all speakers is the same).

Some speakers have a lighter cone and will also move if the air pressure changes within the cabinet. For example, if you do the above battery test on a 212 cabinet with Celestion Vintage 30 and you just give the speakers a short impulse, then it may appear that the speakers are moving in different directions.

In this case, make the battery connection and hold it – the speakers should all move in the same direction and stay there as long as you keep the battery connected.

Checking the Impedance

You can check the impedance of your Palmer PCAB112BX & PCAB212BX Guitar Cabinets using a simple Ohmmeter or Multimeter. Connect a speaker cable to the cabinet and hold the test probes of the multimeter to the other end. Set the Multimeter to Ohms (resistance) and note the reading.

Keep in mind, the reading of the multimeter does not show the impedance (which is frequency dependent), it is just showing the resistance. So the readout will not be exact, but close enough to verify that the speakers are wired correctly. For example, an 8 Ohm speaker can have a readout of roundabout 6.5 or 7 Ohms.

Be sure to test the cabinet with an amp before you take it on tour or to a gig. Start at lower volumes and then slowly increase the level. If there is no sound, nd then stop playing, turn the amp off or to standby, and double-check all the connections.

Calculating Impedances

There are generally two ways to wire two or more speakers. Please see the diagram below.

1. SERIES CONNECTION
2. PARALLEL CONNECTION

General Rule 

• If speakers with equal impedance are connected in series, the impedances are added.
• Example: Two 8 Ohm speakers wired in series will have an overall impedance of 16 Ohms (8 x 2).
• If speakers with equal impedance are connected in parallel, the impedance is divided by the number of speakers.
• Example: Two 16 Ohm speakers wired in parallel will have an overall impedance of 8 Ohms (16 divided by 2).

Glossary

Cabinet Components

Speaker Components

The cone, connected to the voice coil, moves in and out, creating waves of high and low air pressure. The coil and magnet assembly is the ‘motor structure’ of the loudspeaker.

The surround and spider allow the coil to move freely along the axis of the magnet’s core (or ‘pole’) without touching the sides of the magnetic gap.

FAQs

Q: What are the PCAB112BX and PCAB212BX guitar cabinets designed for?

These cabinets provide strong sound projection for practice, rehearsal, and live performances by accurately reproducing electric guitar signals. For more volume and tonal depth, the PCAB212BX boasts 2×12″ speakers as opposed to the PCAB112BX’s 1×12″ speakers.

Q: Can these cabinets be used with tube or solid-state amplifiers?

Indeed, both cabinets work with solid-state and tube guitar amplifiers. Always make sure the output of the amplifier corresponds to the power rating and impedance of the cabinet.

Q: Can I link two cabinets together?

Indeed, depending on the type, the cabinets have either parallel or series outputs. Make sure that the total impedance satisfies the requirements of your amplifier.

Q: Are these cabinets portable?

They do have handles for transportation; however, the PCAB212BX weighs more because it has two speakers. To prevent injuries, use safe lifting techniques.

Q: Can these cabinets be used on stage?

Indeed, both models are prepared for the stage. For better sound projection and vibration control, think about utilising risers or isolation pads.

Q: Are spare speakers available for replacement?

Indeed, Palmer offers replacement speakers that work with these models. For ordering and part numbers, get in touch with customer service.

Q: Can I modify or upgrade the cabinet?

It is possible to make changes (such as installing other speakers), but doing so could impact the warranty and sonic qualities. Before making any changes, always refer to the handbook or Palmer support.
