Your new Fender® Bass Amplification speaker cabinet delivers world-class Fender tone and world-standard Fender quality.
Thank you for choosing Fender®—Tone, Tradition and Innovation—since 1946!
IMPORTANT INFORMATION
• Specification charts for your Fender Bass Amplification speaker cabinet can be found by visiting the Support area of the Fender website at
www.fender.com
.
• Use the Speakon® type input jack on your speaker cabinet whenever possible to take advantage of its superior power transfer efficiency and
locking connector.
• Never connect more than one amplifier to your speaker cabinet, even if more than one jack is labeled "input." Any extra input jacks are for
connecting other speakers (see Parallel Speaker Connections below) or to give you an alternate input plug type, such as Speakon®.
• Never connect speakers with a total impedance load below the minimum rating of your amplifier (see Impedance Guidelines below).
• Never connect speakers with a total power handling capacity below the power output rating of your amplifier.
• Only use unshielded speaker cable of 18 gauge or heavier (such as 16 gauge) for speaker connections. Shielded instrument cable may limit
the power delivered to your speaker and the cable may overheat.
• We recommend removing any casters from bass speaker cabinets to extend your bass response by coupling the cabinet more closely to the
floor.
IMPEDANCE GUIDELINES
Use the impedance ratings on your amplifier and speakers to determine if a particular combination of speakers
is appropriate for your amplifier. NOTE: All Fender® bass speaker cabinet inputs (and most others) are wired in
parallel (not in series), therefore, these Impedance Guidelines apply only to parallel speaker connections.
This Illustration shows the total impedance loads of various combinations of speakers connected in parallel.
Ideally, you will want to connect your amplifier to speakers with a total impedance load equal to the minimum
impedance rating of your amplifier. Operating below the minimum impedance rating can easily overheat
the amplifier and cause damage. Conversely, operating above the minimum impedance rating reduces the
amplifier’s maximum power output capability.
Also notice that different combinations of speaker impedances can equal the same total impedance load.
If speaker impedances are the same in a group, each speaker will receive equal power from your amplifier.
However, if speaker impedances are not the same, speakers with the lowest impedances will receive the most
power. For example, if 4Ω and 8Ω speakers are connected in a group, the 4Ω speaker will draw double the
power and may be louder than the 8Ω speaker. Take this into consideration when calculating power handling
capacities and when positioning your bass speaker cabinets.
PARALLEL SPEAKER CONNECTIONS
Multiple Fender Bass Amplification speaker cabinets can be linked to one
amplifier speaker output as shown (see
Impedance Guidelines
above). Use
any jack {A} as input and any other jack as output to the next speaker.
hORN TwEETER
Adjust the volume level of the tweeter with the Horn Level {B} knob. A
normal setting is half volume, as shown. Note that any distortion from
your amplifier will be accentuated by the high-frequency response of the
tweeter.
The tweeter is protected from overload by an incandescent lamp. If the tweeter stops working, replace the lamp as you would a fuse. The
lamp is located under the input panel. To access the lamp: Remove the 4 screws at the corners of the input panel, then pull the panel out and
up. Use a small flathead screwdriver to remove the blown lamp which is visible through a cutout in the circuit board. There is a spare lamp
stowed on the side of the circuit board (reorder P/N 051857). After inserting the new lamp, reinstall the input panel in the reverse order of
removal.
