XMV power amplifiers, however, can operate in both high-impedance (70V\/100V line) or low-impedance (4?\/8?) modes simultaneously, eliminating the need for additional equipment, as well as streamlining the installation process. XMV power amplifiers also enable both 70V and 100V operation for every pair of channels by simply selecting the preferred mode using the dip switches on the rear panel. High impedance operation often requires the use of two combined channels in bridge mode, but with XMV amplifiers, 70V or 100V mode can be assigned to every pair of channels without affecting the number of available output channels.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eNew \"Double Power Mode\"\u003c\/strong\u003e\u003cbr\u003e The newly developed Double Power Mode function effectively doubles the output power of selected channels in order to drive speakers with higher output power.

This is achieved by automatically switching the circuit to match the corresponding output voltage. In high-impedance connections, both 70V and 100V operation can be achieved since the circuit is already capable of operating in high voltages. However, using the same circuit in lowimpedance operation can mean excessive energy loss, so by automatically switching to a lower voltage drive, efficiency is improved significantly without sacrificing crucial aspects of the amp's performance such as keeping the distortion levels to a minimum.XMV power amplifiers also feature a new switching power supply equipped with Power Factor Correction, which ensures harmonic control and decreases the amount of current draw dramatically, yet still maintains the same output power. This makes circuit breakers less prone to shutting down, as well as eliminating the need for thicker, heavier cables or a larger, more powerful system.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eProtection features for more reliable operation\u003c\/strong\u003e\u003cbr\u003e Automatic protection functions are an essential part of the XMV Series' design, ensuring peak performance and reliable operation in less than ideal situations.

Audio levels that could cause the amplified output to clip are compressed using two dynamic time constants designed to preserve aural transparency. Normal audio level signals remain unaffected by the compressor thereby preserving audio dynamics and preventing the compressor from increasing feedback potential when the amplifier is used for paging.

Examples include projectors with variable audio outputs used in classrooms, boardrooms and video conferencing.\u003c\/p\u003eThe TX-PA40D features two unbalanced line level inputs on high-reliability gold plated phono (RCA) jacks. A front-panel recessed gain control trimmer permits setting the desired amplifier output level for each channel. The gain range accommodates the range of typical unbalanced audio signal levels. Each of the two TX-PA40D outputs will drive a 4 ohm or 8 ohm speaker or multiple speakers connected to present a 4 ohm or 8 ohm load to the amplifier.

Each channel has a two-position switch that sets the output for driving either low impedance or high impedance (70 V) loudspeaker systems, with a +4 dBu sensitivity regardless of load type. RSL works in conjunction with the high headroom power supply and inherently bridged output stage to allow asymmetric loading. Power resources in the amplifier can be utilized to maximum advantage, with one channel producing far beyond its rated output when the other channel has lesser power requirements.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh power density - Up to 2 x 600 W in 1U\u003c\/li\u003e\n\u003cli\u003eCertified Energy Star 2.1 compliant\u003c\/li\u003e\n\u003cli\u003eFlexible - IntelliDrive delivers similar power per channel at 70 V, 2, 4, 8 and 16 ohms\u003c\/li\u003e\n\u003cli\u003eAsymmetric loading allows \"mixing and matching\" of loads with different impedances to maximize both overall system efficiency and inventory utilization\u003c\/li\u003e\n\u003cli\u003ePatented IDEEA output stage based on Class D topology\u003c\/li\u003e\n\u003cli\u003eHigh efficiency - Extremely low power consumption and heat output\u003c\/li\u003e\n\u003cli\u003eExceptionally low cost of ownership over lifetime\u003c\/li\u003e\n\u003cli\u003eRSL switch circuit senses rail voltage and optimizes output for instantaneous load conditions\u003c\/li\u003e\n\u003cli\u003eEfficient cooling - One temperature-controlled fan\u003c\/li\u003e\n\u003cli\u003eComprehensive circuit protection and fault indication\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lab Gruppen","offers":[{"title":"Default Title","offer_id":37787000145,"sku":"506216","price":918.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1835\/6187\/files\/media_7742cade-8f2b-4b49-bf1c-830735ef302a.jpg?v=1763452248"},{"product_id":"jbl-csa2120r-commercial-2-x-120-watt-power-amplifier-1","title":"JBL CSA2120R Commercial 2 x 120 Watt Power Amplifier","description":"\u003cp\u003eThe JBL Commercial® CSA-2120 power amplifier is a professional tool designed and built for installed sound applications.

Atlas DPA amplifiers can be used right out of the box as traditional power amplifiers requiring no programming, special set-up, or network connectivity. However; if you need more from the amplifier, the web enabled DPA Series has an assortment of DSP tools including level controls, EQ’s, limiters, high \/ low pass filters, delays and summing to provide great flexibility for a range of applications.\u003c\/p\u003e\r\n\u003cp\u003eOnce configured, the amplifier can be password protected to prevent unauthorized changes.
