10 PDX3000 Quick Start Guide 11

1. Introduction

1.1 Welcome

Thank you for choosing a Lab.gruppen PDX Series product. This manual provides a comprehensive guide to the features and functionality of PDX Series model
PDX3000 and PDX2000 ampli ers. We highly recommend you read through this manual in its entirety to become fully acquainted

with con guration options and
protection circuitry. As you become thoroughly familiar with all aspects of operation, you may learn of features or options that will a ect your choices on ampli er
modes or loudspeaker system con guration.

Lab.gruppen PDX Series power ampli ers are designed and built with competitive price and good performance and protection features in mind. Although the PDX
Series features a competitive price, each ampli er draws on the engineering that has made Lab.gruppen the benchmark of quality for touring concert systems:
exceptional sonic performance, rugged construction, proven reliability, and protection features that anticipate every unwelcome possibility – that is the core of the
“Show must go on” design philosophy that every Lab.gruppen product is created with, with a well matched feature set per product range depending on the expected
application. This manual was created for the PDX Series 3000 and 2000 ampli er models. Any references to “PDX Series” in this manual refer to all models in the range.

1.2 Features

Your new PDX Series ampli er incorporates a number of sophisticated technologies – many of them proprietary to Lab.gruppen – that ensure the best
possible performance and years of reliable operation. Familiarizing yourself with these technologies will prove invaluable in setting up and optimizing your
loudspeaker system.

1.3 Class D output stage

All PDX Series ampli ers employ our unique IDEEA Class D output stage that is ideally matched to the rated power output. To provide  exibility, each channel o ers
su cient voltage swing and current capacity to drive loads in any impedance without any additional con guration. In order to have low thermal losses as well as a
high voltage swing, the design is based on a permanently bridged output.

1.4 Protection and performance optimization

Appropriate and reliable power ampli cation is vital to any audio system. Inadequate or faulty power ampli ers could cause damage to loudspeakers, or in some cases
to the power ampli ers themselves. To prevent damage or service interruptions, PDX Series ampli ers o er advanced features to protect both internal circuits and
connected loads. These features are part of the Lab.gruppen philosophy “Show must go on”.

Standard on the PDX Series protection features include:

• CPL (Current Peak Limiter) ensures that the ampli er’s output does not exceed the safe current handling parameters of the ampli er components.

• Temperature protection ensures that the ampli er will not be damaged by exceeding thermal limits. The RDY LED  ashes orange when the ampli er approaches

thermal limits to allow user action before protective muting engages.

• DC protection ensures destructive DC signals will not appear at the ampli er outputs. If such conditions occur an internal fuse opens.

• RSL (Rail Sensing Limi ter) is applied to avoid distortion at the selected voltage limit threshold and to avoid hitting the rail if it has sagged below the con gured

threshold. Limiting also may be applied when maximum output current has been reached or when the mains voltage is too low to maintain required rail voltage.
Limiting activity is shown by the front panel Limiter LED

1.5 DSP features and PDX controller software

PDX series feature a comprehensive DSP functions such as crossover, parametric EQ, delay, limiter, dynamic EQ and input mixing, making the PDX series suitable for
a broad range of installed and touring applications. The PDX series can be controlled through the usage of front panel or PDX Controller software by connecting to a
PC with USB.

1.6 Unpacking and visual checks

Every Lab.gruppen ampli er is carefully tested and inspected before leaving the factory and should arrive in perfect condition. If any damage is discovered,
please notify the shipping carrier immediately.

Save the packing materials for the carrier’s inspection and for any future shipping.

1.7 Cooling

The PDX Series devices use a forced-air cooling system with front to rear air ow, allowing high continuous power levels without thermal problems.

Please ensure that there is su cient space in the front and rear of each ampli er to allow free 

ow of air, no doors or covers should be mounted either in the front or

rear of the ampli ers.

Ampli ers may be stacked directly on top of each other with no spacing, though some spacing may enable more convenient installation of rear cab

ling.

Fit solid blanks (not ventilation blanks) to unused rack spaces to ensure e ective air circulation. Leaving gaps in between items of equipment degrades the
e ectiveness of forced-air cooling.

1.8 Operating voltage

Always connect your PDX ampli er to the voltage speci ed on the rear of the device. Connecting the amp to an incorrect voltage can permanently damage your amp.

• USA / Canada / Japan = 100-120 V~, 50/60 Hz

• UK / Australia / Europe / Korea / China 220-240 V~, 50/60 Hz

The locking IEC receptacle on the rear panel accepts the supplied IEC cord which terminates in a connector appropriate for the country of sale.

4.4 PROCESS screens

Pressing the PROCESS button opens up the various screens that determine the signal path setup and that control processing parameters for the DSP modules: I/O, PEQ,
XOVER, DEQ, DELAY, and LIMIT.

You can move between top-level module screens by

pressing the PROCESS button.

4.4.1 I/O

The I/O module sets up the signal routing inside the DSP from input to output. Press and rotate the SELECT encoder knob to choose between dual mono, stereo,
or bi-amped options.

DUAL

DUAL (dual mono) mode routes each channel input, A and B,

through completely separate parallel signal paths with independent outputs for each channel.

Each channel may be processed with its own unique  lter, equalization, signal delay, and limiter settings.

STEREO

STEREO mode routes the signal from both the A and B inputs through a single series of DSP modules. The parallel DSP modules process the A and B signals with
identical, linked settings (only module “A” parameter settings appear on subsequent DSP module screens).

BIAMP1

BIAMP1 mode splits the Channel A input signal at a programmable frequency point, and then routes the resulting high and low frequency signals through a parallel
chain of DSP modules with independent equalization, signal delay, and limiter settings. In BIAMP1 mode, Output A routes low frequencies to a low-range speaker,
while Output B connects to a high-frequency transducer.

BIAMP2

BIAMP2 mode operates identically to BIAMP1 mode, except that the output signals are swapped between Outputs A and B (i.e., Output B handles low frequencies
while Output A handles high frequencies). The swapped A and B output routing allows the user to quickly correct reversed high/low speaker connections without
having to physically access the ampli er’s back panel and manually change the speaker connection.

4.4.2 PEQ

The PEQ module deploys up to eight EQ bands for precise sound sculpting. The EQ bands can each be switched between low shelving, high shelving, and parametric
modes. For the high shelving and low shelving EQ bands, the LS12 and HS12 settings provide steeper equalization curves than the LS6 and HS6 settings.

The main PEQ screen

displays the composite equalization curve across the frequency spectrum.

Programming equalizers

1. Choose individual equalizers by rotating the SELECT encoder knob. As you rotate the SELECT encoder knob, dotted vertical lines will appear at different points
within the frequency spectrum, and the EQ band name will appear in the lower-left corner of the screen (e.g.,

A#1, A#2, B#1, B#2, and so on).

2. Press the SELECT encoder knob to enter the parameter screens for your chosen EQ band.

3. Press the UP / DOWN arrow keys to switch between parameters. The chosen parameter will appear highlighted.

mode, or the cutoff frequency for low and high shelving modes.

7. Set the EQ band’s cut or boost (Gain) by rotating the SELECT encoder knob.

8. For parametric mode, control the width of the parametric curve by tweaking the Q parameter. High Q values produce a narrow, steep curve, while low Q values
create a wide curve with a gentle slope.

9. Press the SELECT encoder knob or the EXIT button to return to the top-level PEQ screen.

4.4.3 XOVER

The XOVER module o ers programmable pairs of high- and low-pass  lters. STEREO mode o ers only one  lter set (A#1). DUAL, BIAMP1, and BIAMP2 modes use two
 lter sets (A#1 and B#1), and in BIAMP1 and BIAMP2 modes, these two sets of  lters may be linked.

On the top-level screen, vertical dotted lines indicate the threshold point for each  lter.

Each low-pass and high-pass  lter also o ers multiple options for  lter type and slope: OFF, Butterworth (BUT6, BUT12, BUT18, BUT24, BUT48), Bessel (BES12, BES24),
or Linkwitz-Riley (LR12, LR24, LR48).

7. Set the link parameter (LinkAB) to ON or OFF by rotating the SELECT encoder knob (BIAMP1 and BIAMP2 modes only).

8. Press the SELECT encoder when

finished to return to the top-level XOVER screen.

4.4.4 DEQ

The DEQ module deploys a dynamic EQ that is triggered by a programmable signal thresold. For example, you can program the dynamic EQ to cut or boost increasing
amounts of mid frequencies as the signal gets louder beyond your preferred threshold.

STEREO mode features one set of dynamic EQs (A#1 and A#2), while DUAL, BIAMP1, and BIAMP2 modes feature two sets of dynamic EQs (A#1, A#2, B#1, and B#2). Each
dynamic EQ may be set to OFF, band-pass (BP), low-pass (LP6, LP12), and high-pass (HP6, HP12).

5.3 Function Tabs

The PDX Controller window allows the user to access DSP functions via embedded tabs accessible near the top of the software window.

The software window includes these tabbed screens:

• • Setup—manages presets and networking options.

• • Configuration—controls the amplifier Mode setting for Dual Mono, Stereo, and other routing options, as well setting controls for output delay and limiting.

• • Filter/Crossover—offers control over adjustable hi-pass and lo-pass filters. In Bi-Amp 1 and Bi-Amp 2 configuration, this tab controls the crossover point for

splitting the blended, mono input signal into separate high- and low-frequency mono signals for bi-amping.

• • Parametric EQ—controls up to 8 adjustable parametric and shelving EQs for each channel.

• • Dynamic EQ—adjusts parameters for 2 bands of level-dependent, dynamic equalization per channel.

5.3.1 Setup

The Setup tab allows you to manage connections and settings for your PDX amps. Amp presets may be stored either on the PDX DSP or on the PC (presets stored on
your PC may then be loaded onto any PDX ampli er).

PC Presets

The PC Presets section allows you to store PDX DSP presets on your computer instead of the PDX amp’s internal memory. The Load function allows you to upload
presets from the computer, while the Save

function stores the current PDX DSP settings to the computer (these  les use a .pdx  lename extension).

5. PDX Controller Software

The PDX Controller software allows the user to control all PDX DSP settings remotely from a computer via the USB connection located on the PDX rear panel.

5.1 Meters

Monitor input and output levels by using the virtual meters on the right hand side of the control software screen. Adjust input levels using the knobs on the ampli er’s
front panel.

5.1.1 Input/Output Meters

The input meters show the signal level at the CH A and CH B inputs. If the input signal exceeds the 0 dB level, the red Clip indicator will light over the channel
experiencing an overload.

The input level can only be controlled by using the CH A and CH B knobs on the front panel of the PDX ampli er. The PDX Controller software does not control
the input level.

5.2 Connection Status

The software displays the connection status in the top header of the main software window.

When the amp/software connection is active, the window heading displays the name of the ampli er.

24 PDX3000 Quick Start Guide 25

Connecting to an amplifier

◊ ◊ this procedure assumes you already have an PDX amplifier connected to your computer, and that you are switching to another PDX amplifer. Usually,

the PDX Controller software will automatically detect a USB-connected PDX amp and then ask if you wish to connect to the detected amplifer.

5.3.2 Configuration

The Con guration tab displays two main sets of software controls:

• • Mode—controls the amplifier configuration. Choose between Dual Mono, Stereo, Bi-Amp 1, and Bi-Amp2 configurations. Each configuration’s complete signal

path appears in the display window, including the arrangement of internal DSP modules and speaker outputs.

• • Delay/Peak Limiter —controls settings for the Delay and Limit DSP modules, as well as options for channel phase, Load settings (in Ohms) for the limiter

wattage display, Hold and Release for the Limiter, and channel linking. The number of Delay/Peak Limiter controls change depending on the amplifier
Mode configuration.

Amp Presets

The Amp Presets section allows you to access and manage presets stored in the PDX amp’s internal memory. The amp’s internal memory holds up to 20 presets, and
these 20 preset slots appear in the Amp Presets section as a numbered, double-column list showing the

preset name and the preset’s signal routing con guration

(DUAL, STEREO, BIAMP1, and so on). The preset currently in use will display an illuminated dot immediately to the preset’s left.

Note: Preset #1:INIT_DATA cannot be overwritten. Select this preset any time you want to restore the amp’s default settings.

Recalling a preset stored in the amp’s internal memory

1. Click on the desired preset in the Amp Presets list. The dot to the immediate left of the selected preset will light up.

2. Click on the Recall button in the upper left of the Amp Presets section. The selected preset’s name will appear in the text box next to the Recall button. All settings
contained in the preset will automatically deploy.

Saving a preset to the amp’s internal memory

replaced by your new preset.)

2. Type your new preset’s name into the text box to the right of the Recall button.

3. Click on the Store button to store your preset in the selected slot in the preset list. Your new preset’s name will appear in the selected slot in the preset list.

Amp Connection

The Amp Connection section tells you which PDX ampli er you have connected to the software, as well as options for naming your PDX amp and for setting up a code
to lock the ampli er’s front panel and prevent tampering (the amp can still be edited from your laptop using the PDX Controller software).

For the current edition of the PDX Controller software, only

one PDX ampli er can appear at any one time in the ampli er list and be recognized by the software.

26 PDX3000 Quick Start Guide 27

Delay/Peak Limiter

Channel Link

In Dual Mono, Bi-Amp 1, and Bi-Amp 2 modes, the Channel Link virtual button will appear just above the Delay and Peak Limiter controls. When you click on the
Channel Link virtual button, the button will light up, and the Delay and Peak

Limiter controls for both channels will display identical values.

Delay

The Delay function digitally slows the  nal signal output from the ampli er by a programmable amount (expressed as either distance or time). This signal delay helps prevent
phase and synchronization problems caused by sound traveling through air over long distances, e.g., between speaker arrays separated by long distances or between a
performance stage and distant sound reinforcement speakers.

The Delay controls also simultaneously display the amount of signal delay in milliseconds (ms), meters (m), and feet (ft), which can be useful if you already know the
precise distance between speakers.

Programming signal delay

1. Program the signal delay by using either of these two methods:

a) Rotate the Delay virtual knob clockwise until you achieve a suitable amount of signal delay. The ms, m, and ft text boxes will each display equivalent values as you

rotate the virtual knob.

b) Type a delay value directly into one of the text boxes below the Delay virtual knob (ms, m, or ft, depending on your preference). The Delay virtual knob will rotate

to a position matching the delay value you have entered.

2. Choose between 0° and 180° phase either by clicking on the Phase virtual button or by clicking directly on 0° or 180° directly below the virtual button. When the
Phase virtual button is engaged, the virtual button will light blue and the indicator next to 180° will light up.

Peak Limiter

The Peak Limiter helps protect your speakers by preventing signal spikes at the ampli er’s output stage.

The Peak Limiter controls include a dedicated virtual knob with matching numerical displays in dBFS (decibels relative to full scale), Vp (Voltage(peak)), as well as a
rating in Watts, which appears only when you choose an Ohm setting from the Load pulldown menu.

The PDX Controller software also allows you to see the ampli er’s total output as a rating in Watts. This Watt rating allows you to connect speakers with lower power
ratings and then adjust the limiter to match the speakers’ maximum Watt rating.

Note: the PDX Controller software does not automatically detect or show the total speaker load connected to the ampli er.

Controls for Hold and Release times appear near the bottom of the window, each with a matching numerical display.

Programming the output limiter

1. Program the output limiter by using either of these two methods:

a) Rotate the Peak Limiter virtual knob counter-clockwise until you find an adequate limiter setting for your sound system. The dBFS (decibels relative to full scale)

and Vp (Voltage [peak]) text boxes will each display equivalent values as you rotate the virtual knob.

b) Type a limiter value directly into one of the text boxes below the Peak Limiter virtual knob (dBFS or Vp). The Peak Limiter virtual knob will rotate to a position

matching the delay value you have entered.

2. Choose a Load value from the Load pulldown menu (none, 2, 4, 8, or 16 Ohms) that matches the total combined load of all speakers connected to the amplifier’s
outputs. If your combined speaker load in Ohms does not exactly match 2, 4, 8, or 16 Ohms, choose the next lower Ohm setting from the Load pulldown menu.
When you select a Load setting, an additional Watt rating for the limiter will appear above the Load pulldown menu.

3. Choose a Hold value either by rotating the Hold virtual knob or by entering a value (in milliseconds) into the matching text box below the knob.

4. Choose a Release value either by rotating the Release virtual knob or by entering a value (in milliseconds) into the matching text box below the knob.

Mode

Changing amplifier mode

The ampli er mode can be changed by clicking on the button for your desired routing option along the left-hand side of the window. When you click on a mode
button, the software will launch a con rmation window. Click “Yes” in the con

rmation window to launch the new ampli er mode, and the new signal path will

appear in the display.

Mode descriptions

Dual Mono

Dual Mono mode routes each channel input, A and B, through completely separate parallel signal paths with independent outputs for each channel. Each channel may
be processed with its own unique  lter, equalization, delay, and limiter settings. The Delay and Limit modules for A and B can be linked and programmed with
identical settings by clicking on the Channel Link button below the Mode window.

Stereo

Stereo mode routes the signal from both the A and B inputs through a single series of DSP modules. Each DSP module processes both the A and B signals with identical,
linked settings. The linked Delay and Limit parameters can be controlled from Stereo mode’s consolidated Channel A+B control window (which displays automatically
when Stereo mode is selected).

Bi-Amp 1

Bi-Amp 1 mode splits the Channel A input signal in the XOver DSP module at a programmable frequency point, and then routes the resulting high and low frequency
signals through a parallel chain of DSP modules with independent equalization, delay, and limiter settings. The Delay and Limit modules for the split high and low
frequency signals can be linked and programmed with identical settings by clicking on the Channel Link button below the Mode window. In Bi-Amp 1 mode, Output A
routes low frequencies to a low-range speaker, while Output B connects to a high-frequency transducer.

Bi-Amp 2

Bi-Amp 2 mode operates identically to Bi-Amp 1 mode, except that the signals are swapped between Outputs A and B (i.e., Output B handles low frequencies while
Output A handles high frequencies). The swapped A and B output routing allows the user to quickly correct reversed high/low speaker connections without having to
physically access the ampli er’s back panel and manually change the speaker connection.

28 PDX3000 Quick Start Guide 29

Filter/Crossover Control View

6. Applications

Refer to the application documentation available for download at labgruppen.com.

6.1 Bi-amping

Bi-amping splits a mono signal into upper and lower frequency bands, and then assigns each frequency band to separate speaker cabinets or separate drivers
within a cabinet. A subwoofer typically takes the low frequency range. By splitting the signal this way, the speakers work more e ciently, and you can achieve a
cleaner overall sound.

Setting up hardware for bi-amping

1. Run a 4-pole speaker cable with professional twist-locking connectors from OUTPUT CH A to the subwoofer (the subwoofer receives its low-frequency signal from
Channel B using poles 2+ and 2-, while the middle and upper frequency ranges use Channel A via poles 1+ and 1-).

2. Set the subwoofer into BIAMPING mode.

3. Run a 2-pole speaker cable with professional twist-locking connectors from the subwoofer to the other speaker.

Programming DSP parameters for bi-amping using the front panel

1. Choose the BIAMP2 setting on the Amp Mode screen.

2. Go to the XOVER screen using the UP/DOWN buttons to set appropriate high/low crossover frequencies.

3. In Channel A#1, choose your high-pass filter type (HPtype: BUT6, BUT12, BES12, etc.) and set the cutoff frequency (HPfreq) to approximately 100 Hz. Deactivate
the low-pass filter (LPtype: OFF) on this channel and set the gain level (Gain) to suit your system.

4. In Channel B#1, choose your low-pass filter type (LPtype: BUT6, BUT12, BES12, etc.) and set the cutoff frequency (LPfreq) to approximately 100 Hz. Deactivate the
high-pass filter (HPtype: OFF) on this channel and set the gain level (Gain) to suit your system.

Programming PDX Controller Software for bi-amping

1. Select the Configuration tab.

2. Choose the BIAMP2 signal path in the Configuration tab. A confirmation window will pop up.

3. Click “Yes” on the Amp Mode confirmation window.

4. Select the Filter/Crossover tab.

5. Select the X-Over button below the Frequency Curve display. A confirmation window will up up asking if you wish to set a Default Crossover.

6. Click “Yes” in the confirmation window. The X-Over button will illuminate, and default crossover settings will appear in the Frequency Curve and Control View.

7. Choose a filter type from either the Low Pass 2 or High Pass 3 Type pulldown menus (the software defaults to a Butterworth filter). Any changes to the Low Pass 2
or High Pass 3 settings will also automatically appear in both filter’s Control View settings.

8. Choose a filter slope setting from the Slope pulldown menu under either Low Pass 2 or High Pass 3 (the software defaults to a Butterworth filter). Again, matching
parameters will automatically appear in both filter’s Control View settings.

9. Set the crossover frequency by using any of these three methods:

a) Rotate the Low Pass 2 or High Pass 3 virtual Freq knobs in the Control View. The crossover frequency displayed in the Freq box below the virtual knob will change

simultaneously for both filters.

b) Select the text box below either Freq virtual knob, and type your desired frequency directly into the text box.

c) Go to the Frequency Curve display, click on the frequency line marked “2,” and drag the frequency line to the desired area of the Frequency Curve. Parameter

settings and virtual knobs in the Control View will automatically move and change as you drag the crossover frequency through the Frequency Curve window.

10. If necessary, adjust the Gain settings for Channel A and Channel B by rotating the respective Gain virtual knobs.

Dynamic EQ Control View

The Control View of the Dynamic EQ tab contains virtual knob controls for Gain, Threshold, Frequency, Q (bandpass  lter only). Exact parameter values appear in boxes
below each virtual knob. These parameters may be altered by either adjusting the virtual knobs or by entering values directly in the parameter boxes.

Pull-down Type menus for each dynamic EQ band contain these additional options:

• • BP (bandpass filter)

• • LP6 (lo-pass filter, with a 6 dB/Octave slope)

• • LP12 (lo-pass filter, with a 12 dB/Octave slope)

• • HP6 (hi-pass filter, with a 6 dB/Octave slope)

• • HP12 (hi-pass filter, with a 12 dB/Octave slope)

The Ratio pulldown menu o ers four options:

Gain vs. Ratio

Positive gain settings result in a frequency boost at low signal levels and a nearly  at EQ response at high levels. Negative gain settings yield opposite results: at low
signal levels, the EQ response is nearly  at, while higher signal levels receive increasing amounts of cut from the equalizer. The higher the Ratio setting, the more the
equalizer will cut or boost the signal at di erent signal levels.

Programming a dynamic EQ

1. Choose an EQ type from the Type pulldown menu.

2. Set the dynamic EQ’s band frequency by rotating the Frequency virtual knob. The programmed frequency can represent either the center frequency for band-pass
(BP) mode, or the threshold frequency for low- (LP) and high-pass modes (HP).

3. For band-pass BP mode, control the width of the band-pass curve by rotating the Quality virtual knob parameter. High Qual values produce a narrow, steep curve,
while low Qual values create a wide curve with a gentle slope.

4. Set the dynamic EQ’s band cut or boost by rotating the Gain virtual knob.

5. Set the signal threshold by rotating the Threshold knob.

6. Program your desired ratio by selecting from the Ratio pulldown menu. Similar to a compressor, higher ratio values yield a more intense equalization effect.

7. Adjust the attack (Attack) and release (Release) values by rotating each parameters respective virtual knob.

Warning! Connecting a full-range speaker switched to bi-amp while using a 4-pole
cable may cause damage to the compression driver. The full-range speaker must be
switched to ‘passive’ mode. Using 2-pole cables between the subwoof

er and

full-range speaker is recommended.

7. Installation

7.1 Rack mounting

Your PDX ampli er  ts into a 19” rack and requires two rack units. Install into the rack using
four attaching screws and washers for the front panel. Consider reinforcing the back panel
using rack accessories (supplied with rack), especially if you will be taking

the PDX on the road.
Make sure enough cool air reaches the rack, especially when other rack equipment emanates
a lot of heat. The PDX ampli ers circulate heat from the front to the rear vents to relieve heat
inside the rack enclosure.

If you are installing multiple power ampli ers into a 19" rack, add  lled panels in the empty
rack spaces to avoid circulation of hot air.

Fan speed adjusts automatically to assure safe operation. Never block ventilation openings.
Should internal temperature reach extreme values, the unit will shut down automatically, and
resume operation when cooled down.

7.2 Connections

Audio inputs

Each channel input uses either XLR or ¼ ” jacks. The XLR jacks can accept balanced XLR connections, while the ¼” jacks can accept both balanced ¼” TRS connectors
and unbalanced ¼” TS connectors. To deploy XLR connectors for unbalanced signals, bridge pins 1 and 3; mono ¼” TS connectors do not require any alteration to carry
unbalanced signals.

When working with balanced signals, please make sure to exclusively use balanced cables. One unbalanced cable in the signal chain can change a balanced signal into
an unbalanced signal.

Outputs

Your PDX ampli er requires speakON twist-locking professional speaker connectors. These professional speaker connectors were developed specially for driving
high-powered speakers. The connectors snap in securely, prevent electric shock, and ensure correct polarity.

The CHANNEL A output contains output pins for both CHANNEL A (1+/1-) and CHANNEL B (2+/2-), so that both channels, if desired, can be sent out simultaneously on a
single 4-pole speaker cable.

The CHANNEL B output, on the other hand, has pin outs for CHANNEL B only (1+/1-).

◊ ◊ Whenever possible, use thick and short speaker cables to minimize power loss.

7.3 Connecting to mains

Always connect your PDX ampli er to the voltage speci ed on the rear of the device. Connecting the amp to an incorrect voltage can permanently damage your amp.

Before powering up the ampli er, double-check all connections and fully lower the gain setting.
