Product information "PRE ST 1"

Permanent installations require solutions which offer a visually discrete design that blends into the background while still being flexible and versatile in their functions. You need to be able to connect different audio sources and manage them, to mute non-priority signals during announcements or emergency calls.

The PRE ST 1 is a 4-channel multi-functional stereo mixer preamplifier that allows users to mix 2 microphone/line sources together with an emergency line input and one of the 3 music sources available, including a Bluetooth receiver. These versatile connection options together with a four-level priority system, that combines contact closure inputs and VOX audio detection circuits, guarantees a seamless integration in almost any commercial audio application.

PRE ST 1 is equipped with two priority contacts: one for the emergency input, which mutes all the other signal sources, and one for the microphone inputs, which mutes the music signal sources. The stereo balanced line output includes a mono/stereo switch and separate tone controls for bass and treble. An automatic standby mode can also be activated in order to further reduce energy consumption when the device is not used.

The intuitive design of its control panel ensures an easy operation, with input and master volume controls, clear signal level and priority indications, and a practical music source selection and Bluetooth pairing activation via capacitive buttons. On the other hand, the clarity of the rear panel and the compact 9.5" format ensures that the preamplifier can be easily installed.

IPA 412 T

Good sound belongs everywhere - in the hotel lobby, in conference rooms, in schools and houses of worship. Demands are constantly increasing, not only in terms of quality, but also in terms of flexibility. Permanently installed and still flexible? This apparent contradiction can be resolved by the IPA Series DSP-based installation amplifiers.The IPA 412 T is a professional, four-channel installation power amplifier with 4 x 120 watts. While the 70V/100V outputs are equipped with high quality toroidal core transformers, the low impedance 4-Ohm outputs are completely transformerless and guarantee the highest possible audio quality. The versatile DSP functions include, amongst others, a parametric EQ with matching speaker library, dynamic tools, a matrix mixer, priority source selection and delay.Despite this range of functions, the IPA Series power amps are easy to operate. Important functions such as signal, limit, protection and bridge mode are easily visible via the LEDs on the front panel.HPF/LPF presets can be enabled directly on the device via DIP switches The IPA 412 T is already equipped for remote control using future remote panels and paging microphones from LD Systems. The back-panel slot provides expansion card connectivity for additional future-proofing. The Ethernet card offers comprehensive configuration and management via software. The Ethernet+Dante card also offers Dante audio networking capabilities and connection to a wide range of Dante-enabled devices, in order to integrate the IPA 412 T into the Dante network and resolve more complex tasks.Times are changing; rooms are redivided or rededicated, numbers of attendees increase or decrease based on unforeseen events, but with the IPA Series DSP-supported power amps, your installation is prepared for any situation. Scalability and future-proofing are the biggest advantages of the IPA Series. Its energy efficiency is also ideal thanks to the class-D technology and switchable auto standby.The IPA 424 T variant with 4 x 240 watts is available for larger installations.

XS 700
XS 700

LD Systems XS700 Power AmplifierThe XS700 is the flagship of the XS series of power amplifiers and an absolute flyweight with just 1U and 3.4kg. Our Class D power amplifier technology makes it possible to pack high performance into a minimum of space without generating unnecessary loss energy. The power amp has an output of 350W per channel at 4 ohms, 2x 200W at 8 ohms, and 700W in bridged mode. It is conceived for all professional applications in which ease of transport and space is essential, whether mobile or in permanent installations.The XS700 has all protection circuits against short-circuiting, DC, overheating, and overloading and has a soft-start delay.The amplifier features XLR, RCA and jack input connectors, with Speakon-compatible sockets and screw terminals as outputs. On the rear panel, it is possible to select the mode of operation and gain and activate the limiter and ground-lift function. LEDs on the front indicate power, signal, clipping, triggering of the protection circuit, and the mode of operation. The XS700 impresses with operational dependability and a transmission range of 20Hz – 20kHz, which is reproduced transparently and dynamically with high impulse fidelity.

MIBS

The LD Systems MIBS is a switchable table stand with LED status indicator for flexible use in meetings, conferences, training and much more. With its sleek and elegant design, the MIBS, which features a robust die-cast zinc alloy, is suitable for businesses, educational institutions, conference centres, educational and administrative facilities or houses of worship.The MIBS tabletop microphone base is compatible with all commercially available gooseneck microphones with XLR3M connectors and offers three operating modes: push-to-talk, push-to-mute and latch ON/OFF. The integrated active audio switching circuitry operates extremely quietly without disturbing the participants in the room.The LED status indicator allows users to see at any time if the microphone is active. When the microphone on the MIBS is muted, the internal attenuation of more than 75 dB ensures that no unwanted information or noise is transmitted. Both the LED display and the active audio circuitry are powered by the 48V phantom power output from a mixing console or preamplifier for the microphone, so they do not require an additional power supply.The integrated low-cut filter takes effect from 100 Hz and ensures transparent speech transmission by reducing annoying low frequency noises - rumbling, humming, vibrations - which typically occur during desktop operation. The non-slip long rubber feet on the underside of the housing also reduce the effects of shocks and vibrations on the microphone. For optimal signal transmission to mixing amplifiers and consoles, the active audio circuitry in MIBS provides an extra+5 dB gain. This also helps to solve audio signal loss issues due to long cable runs.

PAM
PAM

The LD Systems PAM is a high-quality gooseneck table microphone that can be used for general announcements over permanently installed public address systems in retail stores, schools, warehouses or other public areas. Three announcement modes are available via the central, configurable push button: Push-to-Talk, Push-to-Mute, Latch On/OFF. The integrated LED microphone symbol indicates whether the PAM is active, i.e. in use.PAM includes a robust desktop base, which features non-slip long rubber feet on the underside of the housing to ensure a secure stand at all times and minimise the effects of knocks, vibration and structure-borne noise on the microphone.In addition to the balanced audio output, the PAM also features a hard-wired contact closure output that allows priority mutes to be triggered in mixer amplifiers and zone mixers via a MOSFET switch.This makes the paging table microphone perfect for use in combination with the LD Systems mixing amplifiers of the IMA series or the ZONE mixers. At the same time, it is compatible with all third-party devices that have a microphone and contact closure input. For optimal signal transmission, the PAM sends signals with a gain of +5 dB. This also helps to solve sound loss issues with long cable runs.The integrated low-cut filter attenuates frequencies below 100 Hz and ensures transparent speech announcements without annoying, low-frequency background noise, which is usually caused by humming or vibrations during tabletop operation.
