Congratulations! With buying an DYNACORD LX power amplifier you have chosen a state-of-the-art appliance that employs most advanced technology.
LX power amps combine outstanding audio performance, highest reliability and operational safety.
The audio performance of LX power amps are simply extraordinary. The new switchmode power supply technology, completely designed from scratch and the consistent use of Class-H technology provide extensive headroom far above the stated nominal output and conspicuous reduction in leakage power at the same time.
The employed switching power supply combines the headroom-advantage of a transformer power amplifier with low weight of a pulsed power supply unit resulting in an improved performance-to-weight ratio. Special attention had been given to high efficiency and interference immunity already in the designing stage with the result that trouble-free operation of LX power amps is possible even in EMV-critical environments.
The power amplification stages of the LX amps follow Class-H technology design, i.e. the power amp provides extremely fast, signal-dependent operating voltage switching, which, results in doubling the regular supply voltage when needed. Compared to Class-AB power amps, Class-H power amps generate by far less power dissipation at identical output. Consequently, reduced leakage power or dissipation is synonymous to less waste heat. In other words: energy is used more efficiently! As a result, installing Class-H power amps within rack shelf systems is possible with less space between appliances. In addition to that and despite offering identical output, power consumption is a lot less than in Class-AB operation.
Being protected against thermal and electrical overload, short circuit and the occurrence of HF/DC at the outputs, DYNACORD LX power amps fulfill even the most demanding requirements of Pro-Audio touring applications. Back-EMF-Protection eliminates the risk of the output transistors being damaged by electrical energy back-feed. The power outputs are switched via relay with a time delay during soft-start and an inrush current limiter additionally prevents mains fuses from blowing.
Mechanical construction and workmanship also comply with the highest precision manufacturing standards. The robust chassis is extremely rigid which makes it especially suitable for wearing touring applications. Two three-speed high performance fans (off/slow/fast) guarantee outstanding thermal stability at absolute low running noise. Front-to-rear ventilation allows trouble-free operation even in smaller amp-racks. The electronically balanced inputs are carried out via XLR-type connectors. Direct-Outs for through connecting the audio signal are also provided via XLRM-type connectors. Input Routing allows selecting DUAL (stereo) or PARALLEL (monaural) operation mode. By means of the separate BRIDGED OUT-connector and a Bridged Mode-switch, switching to "Mono Bridged" operation is truly uncomplicated as well. The recessed mounted dB-scaled level controls ensure reliable protection against mechanical damage. These particularly precise, secure to operate detent-potentiometers are located on the front panel. LX power amps provide the opportunity for retrofitting an internal analogue signal processor board with x-over and filter functions. The easily readable LED display provides a quick overview of the power amp's current operational status. The power outputs CHANNEL A, CHANNEL B and BRIDGED OUT are carried out as extremely durable SPEAKON-type connectors. Also located on the rear panel is a Ground-lift switch, which, when needed, helps eliminating ground-noise loops by separating the power amp's enclosure from the circuit ground. In normal operation, all LX power amps are capable of driving loads as low as 2ohms. In Mono-Bridged mode the allowable minimum load is 4ohms.
This owner's manual outlines and explains several other features of your LX power amplifier. Please, make sure to carefully read all of it and mind the instructions.
UNPACKING & WARRANTY
Carefully open the packaging and take out the power amplifier. Next to the power amplifier itself, the package also includes this owner's manual, a mains cord and the warranty certificate. Keep the original invoice, which states the purchase/delivery date together with the warranty certificate at a safe place.
INSTALLATION NOTES
Generally, installing or mounting LX power amps should be carried out in a way that guarantees continuously unopposed front-to-rear air circulation. Installation of appliances with opposite air circulation within one cabinet or closed rack shelf system is not recommendable. When including appliances in a closed cabinet or rack shelf system make sure to provide sufficient ventilation. Leave a gap of at least 60mm × 330mm (up to the cabinet's top ventilation louvers) for air circulation between the rear of the power amplifier and the cabinet's/rack's rear inner wall. Make sure to leave at least 100mm of space above the cabinet or rack shelf system. Since temperatures inside of the cabinet or rack shelf system can easily rise up to 40^ during operation, bearing in mind the maximally allowable environmental temperatures for all other appliances installed in the same rack shelf system is mandatory (also refer to "MAINS OPERATION AND RESULTING TEMPERATURE").
Caution: For trouble-free operation exceeding the maximally allowable environmental temperature of +40^ is not permissible.
To prevent the front panel from bending, the use of installation rails or optionally available "rear-rackmount" rails is obligatory when installing the appliance in a rack shelf system or cabinet.
The power amplifier has to be protected against: dripping or splashing water, direct sunlight, high temperatures or direct influence of heat sources, high humidity, extensive dust and vibrations.
If guaranteeing the listed requirements is not possible on a long-term basis, regular servicing is absolutely mandatory to prevent the power amplifier from possible failure, mainly being caused by negative environmental effects.
Condensation on internal parts may occur when transporting the power amplifier from a cold into a warmer environment. In that case operation is only permissible after the appliance has gained the new temperature (after approximately one hour). If foreign objects or liquids have entered the power amp's enclosure, make sure to immediately separate the appliance from the mains power and contact an authorized service center for inspection before continuing operation.
FCC INFORMATION (U.S.A)
- IMPORTANT: Do not modify this unit! Changes or modifications not expressly approved by the manufacturer could void the user's authority, granted by the FCC, to operate the equipment.
- NOTE : This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception , which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Use the POWER switch located on the front panel to power-on the appliance. The soft-start function protects against current inrush peaks on the mains, which in addition prevents the mains line protection switch from activating during power-on. The loudspeaker outputs are activated via relay switching with a delay of approximately 3 seconds to efficiently attenuate eventual power-on noise. The PROTECT LED lights during the delay time and the fans run at maximum speed. This is normal, confirming the immaculate operation of the protection circuitry.
POWER
This indicator lights when the power amplifier has been switched on. Causes for the POWER-indicator not lighting are: the appliance is not connected to the mains network or a defective primary fuse.
PROTECT
The PROTECT LED lights indicating that one of the internal protection circuits against thermal overload, short-circuit, Back-EMF, HF-occurrence at the output, etc., has been activated. The output relays interrupt the connected loads from the power amps while input signals are interrupted as well, preventing the connected loudspeaker systems and the power amplifier itself from being damaged. Whatever caused the fault - e.g. a short-circuited speaker cable - needs to be remedied. In case of thermal overload you have to wait until the power amplifier automatically regains normal operation.
SIGNAL
The SIGNAL LED lights as soon as an audio signal of approximately 30dB below full modulation is present at the output. The LED is dimmed when speaker cables are short-circuited or a protection circuit has been activated.
0 dB
The 0dB LED lights whenever the power amplifier is driven at its limits. Higher input voltage does not result in higher peak output voltage. In addition, the 0dB indicator comes in handy when adjusting external limiters.
LIMIT
This indicator lights as soon as the integrated dynamic audio signal limiter is activated and the power amplifier is driven at the clipping limit or generally at its maximum capacity. Short-term blinking is not a problem, because the internal limiter trims input levels of up to +21dBu down to an S/N-ratio of approximately 1% . If, on the other hand, this LED lights constantly, reducing the volume is recommended to prevent the loudspeaker systems connected from being damaged by probable overload.
Detent potentiometers scaled in dB (steps of 1dB) for adjusting the power amp's overall amplification. To prevent distortion in mixing consoles connected to the amp, setting these controls to a value between 0dB and -6dB is generally recommended. The dB-scale provides direct indication of the control attenuation applied to the fixed internal amplification.
INPUT A / INPUT B
The inputs INPUT A & INPUT B are electronically balanced offering input sensitivity of
+4.7dBu /1.33V (LX1600),
+5.8dBu /1.51V (LX2200),
+7.0dBu /1.74V (LX3000),
for direct connection of mixing consoles, signal processors, etc.
The XLR-type connectors OUTPUT A & OUTPUT B are prepared for "through-connecting" input signals to additional external power amps. The input signal is directly routed to these output connectors. There are no repeaters or other electronic components within that signal path. Accordingly, input and output connectors of the corresponding channel are interconnected in parallel, offering permanent electrical connection, without regard to the setting of the Power-ON switch.
Although having XLR-type output connectors, some mixing console models provide unbalanced output connection only. When using mixers with unbalanced outputs, bridging PIN1 and PIN3 of the power amp's input connectors or leaving PIN3 of the cable's plugs unconnected is necessary. Otherwise, when feeding in unbalanced audio signals via PIN3 (b, -, „cold“) and PIN2 (a, +, „hot“), strange humming and HF-interference may occur, which very likely will damage the power amplifier and/or the connected speaker cabinets.
NF-CONNECTION CORDS
Choosing high-quality balanced cables (two conductors for the audio signal plus separate shielding mesh) with XLR-type connectors is recommended for LF-signal connection. Although connecting unbalanced cables to the power amplifier inputs is possible as well, using balanced cables is always preferable. A great number of today's audio appliances employ balanced outputs. With balanced cabling, the shield connects all metal enclosure parts and therefore efficiently eliminates the introduction of external interference – mostly noise and hum.

XLR (male)
XLR (female)
PARALLEL
The input connectors of channel A and channel B are electrically connected in parallel when the selector switch is set to PARALLEL. However, individually controlling the volume of both channels is still possible via the corresponding level controls A and B.
DUAL
If the selector switch is set to DUAL, the audio signals of channels A and B are independently amplified.
POWER AMPLIFIER OUTPUT CONNECTORS
Power amp output connection for the two channels A (left) and B (right) is provided via professional SPEAKON connectors. These offer an electrical and mechanical secure connection which complies to all security regulations. It also allows the use of high quality speaker cables with a diameter of 4 × 2.5 mm^2 . The DYNACORD accessory assortment includes recommended cables and connectors. A plastic cover to prevent inadvertent erroneous connection protects the BRIDGED OUT connector. Remove the cover only when actually operating the power amplifier in Bridged-Mode.
CAUTION!
Pins 2 + / 2- of the CHANNEL A SPEAKON output, which normally are not in use, are also connected to output B to ensure comfortable connection of 2-way speaker cabinets (e.g in Bi-Amping Mode) when using 4-wire Speakon cables. To prevent short-circuit and/or to protect your speaker systems from being damaged when connecting the cabinets, please make sure to mind the Low- and High channels' specific pin-assignments! If, for example, the subwoofer audio signal is used to feed a tweeter, it is more than likely that this will instantly destroy the HF-driver's coil.
WARNING:
The speaker output terminals are marked with a symbol “ ”, which signifies that these terminals present a shock hazard to the user.
BRIDGED MODE
With the BRIDGED-MODE switch being engaged, using the channel A input for audio signal feed is mandatory, since input B provides no function. While the amplifier of channel A operates as usual. Additionally, the audio signal is internally inverted and routed to the amplifier of channel B. Both amps - A and B - now work in push-pull operation to provide doubled output voltage at the BRIDGED-OUT connector.
The regular output voltage of each amplifier channel A + B is still present at the corresponding output connectors CHANNEL A and CHANNEL B. However, using these signals is not recommendable because of the aforementioned phase inversion. Operating the power amp in Bridged Mode with loads of 2ohms connected is not allowable.
CAUTION: Operating the power amplifier in Bridged-Mode may result in extremely high voltages being present at the BRIDGED OUT connector. The connected loudspeaker systems have to be designed for handling such high voltages. Please carefully read the power handling specifications as stated in the documentation of the according loudspeaker system and make sure to check whether they are in compliance with the output capacity specifications of the power amplifier.
GROUND-LIFT SWITCH
The ground-lift switch allows eliminating noise loops. When operating the power amplifier in a 19^ rack-shelf system or cabinet together with other equipment, setting the switch to its GROUNDED position is recommended. When operating the power amplifier together with appliances with differing ground potentials, set the switch to its UNGROUNDED position
MAINS INPUT
Under normal circumstances, the mains fuse only blows in case of fault. Replacing the fuse is only permissible for authorized service personnel using a new fuse of the same type with identical amperage, voltage and blow characteristics. The high-performance mains cord supplied with your
power amplifier complies with applicable safety regulations, plus that its diameter corresponds to the power amp's power output capacity. Whenever possible make sure to use the supplied mains cord for connecting the power amp to the mains network. Using a different mains cord with a smaller diameter results in higher leakage, consequently reducing the amplifier's maximum power output capacity.
The following tables are useful in determining power supply and cabling requirements.
The power drawn from the mains network is converted into acoustic output to feed the connected loudspeaker systems plus heat. The difference between drawn power and dispensed power is referred to as leakage power or dissipation (P_d) . The amount of heat resulting from power dissipation might remain inside of a rack-shelf and needs to be diverted using appropriate measures. The following table is meant as auxiliary means for calculating temperatures inside of rack-shelf systems/cabinets and the ventilation efforts necessary.
The column "Pd" lists the leakage power in relation to different operational states. The column "BTU/hr" shows the dispensed heat amount per hour.
