• Gli impianti elet trici nei locali prescelti per l'uso dell'apparecchio rispondono alle
normative stabilite dall'ANSI.

• L'apparecchio viene utilizzato come indicato nel libretto delle istruzioni per l'uso.

AVVERTIMENTI:

• In caso di ap ertura di parti di rives timento o rimozione di p arti dell'involucro,
a meno che no n si tratti di pezzi rimovibili semplicemente a mano, possono venire alla
luce parti dell'a pparecchio conduttrici di te nsione.

• Se l'apertura del l'apparecchio dovesse risultare necessaria è indispensabile staccare
precedentemente quest 'ultimo da tutte le font i di tensione. Rispettare tale misura di
prevenzione anche prima di un allineamento, di operazioni di manutenz ione, della
messa in esercizi o o della sostituzione d i componenti all'interno del l'apparecchio.

• Allineamento, operazi oni di manutenzione o ev entuali riparazioni dell'apparec chio
in presenza di tensione vanno eseguite es clusivamente da personale sp ecializzato ed
autorizzato, in g rado di eseguire tali op erazioni evitandone i rischi connessi.

• Le uscite degli altoparlanti contrassegnate d ai caratteri IEC 417/5036 (vedi
illustrazione 1 a fondo pag.) possono ess ere conduttrici di tensione pericolosa con
cui evitare il contatto. Per questo motiv o, prima di accendere l' apparecchio, collegare
quest'ultimo agli altoparlanti servendosi esclusi vamente del cavetto d'allacc iamento
indicato dal prod uttore.

• Tutte le spine e i cavi di collegamento devono es sere avvitati o fissati all'involucro
dell'apparecchio per quanto possibile.

• Utilizzare esclusivam ente fusibili del tipo I EC 127 con la indicata corrente nominale.

• L'utilizzo di fus ibili di sicurezza non i ntegri e la messa in corto circuito del sostegno di
metallo sono proi bite.

• Non interrompere mai il collegamento con il circuito di protezione.

• Superfici contrassegn ate dalla parola "HOT" ( vedi illustrazione 2 a f ondo pag.),
cosi come griglie di aerazione, dispositivi di raffreddamento e i loro rivestimenti di
protezione, oppure valvole e i relativi r ivestimenti protettivi possono surriscaldarsi
notevolmente durante l'uso e per questo m otivo non vanno toccate.

• L'ascolto di suon i ad alto volume può provocare danni permanenti all'udito. Evitate
perciò la diretta vicinanza con altoparlanti ad alta emissione di suono
e utilizzate cuff ie protettive in caso ci ò non sia possibile.

ALIMENTAZIONE:

• L'apparecchio è c oncepito per il funzionament o continuo.

• La tensione di esercizio deve corrispondere alla tensione di rete a cui ci si allaccia.

• L'allacciamento alla rete elettrica avviene t ramite alimentatore o cavett o
d'alimentazione conse gnato insieme all'apparecchio.

• Alimentatore: un cavo di connessione danneggi ato non può essere sosti tuito.
L'alimentatore non può più essere utilizzato.

• Evitate un allacciame nto alla rete di corrent e utilizzando cassette di distribuzione
sovraccariche.

• La spina di c orrente deve essere situata nelle vicinanze dell'apparec chio e facilmente
raggiungibile in qualsiasi momento.

LOCALI DI COLLOCA MENTO:

• Opportuno collocare l'apparecchio su una supe rficie pulita e orizzontale.

• Non sottoporre l' apparecchio in funzione a scosse e vibrazioni.

rispettate.

• Evitare di esporre l'apparecchio ai raggi del sole e di collocarlo direttamente nelle
vicinanze di font i di calore come calorif eri, stufette, ecc.

• Se l'apparecchio viene trasportato rapidamente da un locale freddo ad uno riscaldato
può succedere che al suo interno si c rei della condensa. Ciò va tenuto in considera­zione soprattutto in caso di apparecchi a valvole. Attendere che l'apparecchio abbia
assunto la temper atura ambiente prima di accenderlo.

• Accessori: non co llocare l'apparecchio su car relli, supporti, treppiedi, superfici o tavoli
instabili. Se l'a pparecchio dovesse cadere a terra potrebbe causare d anni a terzi o dan­neggiarsi irreparabil mente. Utilizzate per il collocamento dell'apparecchio s upporti,
treppiedi e super fici che siano consigliate dal produttore o direttam ente comprese
nell'offerta di v endita. Per il collocamento dell'apparecchio attenetevi strettamente
alle istruzioni d el produttore, utilizzando e sclusivamente accessori da e sso consigliati.
L'apparecchio in combinazione ad un supporto va spostato con molta attenzione.
Movimenti bruschi o il collocamento su pa vimenti non piani possono provocare la
caduta dell'apparecch io e del suo supporto.

• Accessori supplementa ri: non utilizzate mai a ccessori supplementari che n on siano
consigliati dal p roduttore, potendo essere ci ò causa di incidenti.

• Per proteggere l' apparecchio in caso di t emporali o nel caso ques to non venisse utiliz­zato per diverso tempo si consiglia di staccarne la spina di corrente.
In questo modo si evitano danni all'appar ecchio dovuti a colpi di fulmine o ad improv­visi aumenti di tensione nel circuito di corrente alternata.

1 Description

The XBA 18 is a professional-class subwoofer loaded
with one 18" woofer. It sports one onboard single­channel PWM power amp (class-D) with integrated
control circuitry. These features let you adjust para­meters such as levels, the upper frequency limit, and
polarity directly at the XBA 18 without resorting to
an outboard controller. If you wish to use the XBA 18
with a DDO- or controller-driven system, you can flip
the Crossover switch to cut the integrated circuitry
out of the signal path.

2 Features

2.1 Digital or Analog Signal Sources

You can operate the XBA 18 in two ways. The analog
preamp features a variable cutoff frequency, making
it easy to connect and adapt the enclosure to any
given audio system. Once you active the crossover
by setting the Crossover switch to On, you can ad­just the cutoff frequency within a range of 60 to
100 Hz. The Gain knob is always active; it adjusts
the XBA 18’s input sensitivity to match it your
system’s signal level.

No further adjustments are necessary when you feed
a DDO-controlled signal to the XBA 18 (Gain +6 db).
The Crossover switch deactivates the crossover.

2.2 Digital Amping – Enhanced Efficiency and
Dynamics

With an efficiency rating topping the 90% mark,
Class-D digital power amps are far smaller, lighter,
and more compact than conventional amps. The
reduced thermal load on components clearly
increases reliability. The slew rate is much faster and
the attenuation factor much higher, resulting in
markedly more responsive and accurate
performance.

2.3 Power Amp

The single-channel PWM power amp is housed in a
separate chamber within the XBA 18. It comprises
limiter and protection circuits as well as a mains
power unit.

Integrated Protection Circuits

The XBA 18’s power amp is equipped with circuits
protecting it against overcurrent at the speaker out­put, as well as against overheating. The Protect LED
on the rear panel lights up when a protective circuit
activates.

2.4 Fan

Continuously running fans serve to cool the XBA 18.
They draw fresh air from the left vent and expel the
warm air through the right vent (as viewed from
back of the XBA 18). Located behind the vents are
5 mm foam rubber dust filters.

Important note!

Remove the metal panel to check the dust filters
regularly. Clean or replace clogged filters to ensure
ventilation is sufficient to cool the amp. Ensure the
vents at the back of the XBA 18 remain uncovered
and unobstructed.

2.5 Integrated Controller Circuitry

The XBA 18 is equipped with an active controller
providing crossover and limiter functions.

Input Circuit

The XBA 18’s audio input is electronically balanced.
Input impedance is >47 k-ohms. The maximum
input level is 22 dBu. The audio input is furnished
with a high-frequency filter that prevents it from
picking up stray high-frequency noise.

Filter Functions

The integrated crossover function comprises a low­pass filter with a 12 dB / octave slope and a variable
upper frequency limit that is adjustable within the
range of 60 to 100 Hz. The audio signal’s polarity
can be inverted 180 degrees to match the polarity of
the PA requiring sub-bass reinforcement.

The XBA 18’s integrated crossover function is
not required when an external active controller
(for example, the DDO or DFC) is used to drive
the XBA 18. In this case, you can circumvent the
XBA 18’s crossover by flipping the Bypass switch.

A 20-Hz electronic high-pass called the Subsonic
Filter cuts extremely low frequencies from the audio
signal path. Although hardly audible, these ultra
low frequencies could push the 18" woofer too
hard, causing the membrane to travel too far and
destroying the speaker.

Note:

The Subsonic Filter and the XBA 18’s Polarity switch
remain in the signal path when the crossover is
bypassed.

2.6 Limiter

The XBA 18’s integrated controller circuitry is
equipped with a peak limiter that protects the
power amp and connected speakers against
excessively high signal levels.

XBA 18 Manual 1.0

3 Connectors and Control

Features

Connectors and control features are mounted out
of harm’s way on a recessed panel on the rear of
the XBA 18.

1 Crossover

Engage this bypass to remove the XBA 18’s integra­ted crossover from the signal path. This is necessary
whenever you use an external active controller (for
example, the DDO or DFC) to drive the XBA 18.

2 Frequency

Twist this knob to dial in the integrated crossover’s
upper frequency limit within a range of 60 to
100 Hz. This setting depends on the sound rein­forcement system connected to the XBA 18.

3 Gain

Twist this knob to dial in levels for the 18" woofer in
the XBA 18. The standard setting is +6 dB.

4 Left/Mono Input (XLR- female)

Connecting cords: Feed the signal from your mixer
(master left/right, line out, or similar circuit) to the
balanced Input ports using a standard XLR micro­phone cord. Ensure the XLR plugs’ pin assignments
are pin (1) = ground, pin (2) = signal (+),
pin (3) = signal (-).

More about pin assignments

The XLR port’s pin assignments comply with the in­ternational IEC 268-12 standard. In accordance with
this standard, pin 1 is the ground, while pin 2 carries

the positive signal and pin 3 the negative signal.
The stereo 1/4" jack’s tip carries the positive signal,
its ring carries the negative signal, and the ground
circuit is routed via the sleeve. When you insert an
unbalanced mono plug, the input’s unbalanced ope­rating mode is automatically engaged.

5 Through Left (XLR-male)

Connecting cords: This is a parallel output for
routing the line signal (left or right) to other
systems, outboard components, monitor power
amps, etc., via XLR cords.

6 Right Input (XLR-female)

Connecting cords: Feed the signal from your mixer
(master left/right, line out, or similar circuit) to the
balanced Input ports using a standard XLR micro­phone cord. Ensure the XLR plugs’ pin assignments
are pin (1) = ground, pin (2) = signal (+),
pin (3) = signal (-).

7 Through Right (XLR-male)

Connecting cords: This is a parallel output for
routing the line signal (left or right) to other
systems, outboard components, monitor power
amps, etc., via XLR cords.

8 Phase

Use this switch to determine the XBA 18’s polarity.
This setting depends on the sound reinforcement
system connected to the XBA 18.
0°: The XBA 18’s polarity is positive (in phase).
180°: The XBA 18’s polarity is negative (out of

phase).

9 Protect LED

Dedicated LED for the power amp channel light up
red to indicate the XBA 18 has switched to Protect
mode due to power overload, overheating or an in­ternal problem. When in Protect mode, the XBA 18’s
power amp channel is muted.

10 Signal und Clip LEDs

Dedicated LEDs for the power amp channel indicate
the incoming audio signal’s level.

11 Power LED

Dedicated LED for the power amp channel light up
blue to indicate the XBA 18 is switched on and ready
to operate.

12 Power Switch

Handling: On/off switch for the XBA 18.
Note: Once you have engaged the Power switch,
it will take several seconds for the display to light
up and the system to be ready for operation. This
is standard procedure and does not indicate a
malfunction.

Like any active speaker, the XBA 18 should always be
switched on last after you switch on all connected
devices, and switched off first before you switch off
all connected devices.

13 Mains Input

Connecting cords: Use the factory-included
PowerCon mains cord to connect this socket to a
wall receptacle.

Caution! Make sure the local mains voltage matches
the voltage specified on the device. Connecting the
system to the wrong mains voltage may destroy the
XBA 18’s electronic components.

4 Tips and Tricks

• Do not expose electronic circuitry to moisture!
When you set the Subwoofer up outdoors, be sure
to protect it against rain. Keep soft drinks, beer
or any other liquids well away from the cabinets
to protect their electronic components from short
circuits.

• To ensure proper ventilation, make sure the sub
woofer is placed a sufficient distance away from
walls and isn’t covered by curtains and the like.
This is vital to keep the power amps cool.

• Ensure that the vents on the subwoofer’s side
panels are free of dirt and that the fans can rotate
freely. Otherwise, electronic components may
overheat and suffer damage.

• The XBA 18 delivers optimum sound, so you should
provide it with optimum input signals! Noise
such as humming is generally caused by defective
cables, the wrong type of cords, or unbalanced
signals routed into the mixing console.Check all
signal and mains cables.

• Prevent distortion! Not only is it unpleasant to your
audience’s ears, it also endangers your equipment.
Make sure all components connected directly
and indirectly to the XBA 18 have sufficient power
ratings, and that they don’t distort because they‘re
running at their respective limits. Provide an
undistorted signal that doesn’t have to be cleaned
up by backing off the Gain knob.

• Avoid ground loops! You may encounter a ground
loop when the mixer is grounded via a mains cord
which isn’t connected to the same mains circuit
as the XBA 18. To prevent this problem, always
connect the XBA 18 and the mixing console to the
same electrical circuit(same phase!).

CAUTION: Never tape over the plug’s ground
terminal—this endangers lives!

6 Troubleshooting

The POWER LED does not light up when
switched on.

1 Check if the PowerCon mains cord is plugged into

the Mains Input.

2 Check if the mains power supply is providing

current.

The system is on, but no sound is issuing from the
speaker.

1 Check the cord connected to the Input.
2 Check if the signal sources (mixer, keyboard, CD

player) are on.
3 Is the Gain knob turned up?
4 Check the speaker cords for defects.
5 Check if the Speakon connectors are engaged in

their sockets (rotated to the right). They must
be locked in place to establish an electrical
connection.

The subwoofer’s low frequency output is weak.

1 Check the Gain knob setting. Adjust it to set the

subwoofer’s volume to the desired level.

The rendered signal sounds distorted.

1 Check the LED displays on your mixer. They should

not be constantly in the red. If necessary, back off
the volume at the mixer.

2 If the LED displays on your mixer are in the green,

back off the XBA 18’s Gain knob.
3 Observe the LEDs of the Limit Left, Limit Right

and Limit Subwoofer displays on the XBA 18’s
control panel. These may light up yellow, but only
intermittently. Under no circumstances may they
continuously illuminate yellow. If this is the case,
turn down the Gain knob.

Annoying humming

1 Check the cords connecting the signal source to

the XBA 18. Replace defective cords.

2 If you cannot pinpoint the cause of the humming,

engage the Ground switch. This should remedy the
problem in most cases.
