In that case, you need a DI box - and a high-quality one at that - to ensure your sound won't be compromised.\u003c\/p\u003e\n\u003cp\u003eThe BRIDGE 4A from Palmer is a 4-channel, active DI box in 19\" rack format for feeding the unbalanced and high-impedance signals of electric instruments such as guitar, bass, keyboard or synthesiser into the microphone inputs of a mixing console. It provides a transformer-balanced, low-impedance signal at the outputs and eliminates mains hum and interference caused by ground loops. This keeps the sound unadulterated: brilliant, low-noise and without interference.\u003c\/p\u003e\n\u003cp\u003eEach channel is equipped with a 6.3 mm jack input, a THRU-Out (for forwarding the input signals to an amplifier, for example), and two transformer-balanced XLR outputs - one at the front and one at the rear.\u003c\/p\u003e\n\u003cp\u003eThanks to a switchable 30dB pre-attenuation, the BRIDGE 4A can be fed with extremely high input levels in addition to line signals, which means it can even be looped in between the amplifier output and speakers, for example. The Audio-Over-Cat output enables the signals of all 4 channels to be routed via a single Cat (Cat5e or higher) cable. This saves material, space and time. The active circuit leaves the frequency response unaffected, achieves a high dynamic range and delivers a higher output level than a passive DI box.\u003c\/p\u003e\n\u003cp\u003eThe BRIDGE 4A is the ideal solution for audio technicians, semi-professional and professional musicians as well as recording studios that value reliable and durable products.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul class=\"mb-0 relative overflow-hidden min-h-[120px]\"\u003e\n\u003cli\u003eBalancing and impedance matching for guitar, bass, keyboards \u0026amp; synthesizers\u003c\/li\u003e\n\u003cli\u003eEliminates ground loop hum thanks to galvanic transformer isolation\u003c\/li\u003e\n\u003cli\u003e4 independent DI boxes in a solid 19\" housing (1U)\u003c\/li\u003e\n\u003cli\u003eHigher output level than a passive DI box\u003c\/li\u003e\n\u003cli\u003eTHRU-output for passing the input signal\u003c\/li\u003e\n\u003cli\u003eAudio over Cat output (AES72 Type 5e) for forwarding all signals via a single Cat cable\u003c\/li\u003e\n\u003cli\u003ePure and unaltered low-noise audio\u003c\/li\u003e\n\u003cli\u003eHandles even high-level inputs without distortion thanks to switchable -30dB pad\u003c\/li\u003e\n\u003cli\u003eGround-lift switch for each output\u003c\/li\u003e\n\u003cli\u003ePower supply: 9V DC, center negative\u003c\/li\u003e\n\u003cli\u003eEngineered in Germany\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProduct type: DI boxes\u003c\/li\u003e\n\u003cli\u003eType: active\u003c\/li\u003e\n\u003cli\u003eTransformer isolated: yes\u003c\/li\u003e\n\u003cli\u003eChannels: 4\u003c\/li\u003e\n\u003cli\u003eInputs: 4\u003c\/li\u003e\n\u003cli\u003einput type: unbalanced\u003c\/li\u003e\n\u003cli\u003eInput connectors: 6.3 mm jack\u003c\/li\u003e\n\u003cli\u003eInput pad: 0 dB \/ 30 dB\u003c\/li\u003e\n\u003cli\u003eNumber of outputs: 4 (+ 4 parallel XLR outs + AoC)\u003c\/li\u003e\n\u003cli\u003eTHRU outputs\/channel: 1\u003c\/li\u003e\n\u003cli\u003eOutput type: balanced\u003c\/li\u003e\n\u003cli\u003eOutput connectors: XLR, RJ45\u003c\/li\u003e\n\u003cli\u003eCabinet material: sheet steel\u003c\/li\u003e\n\u003cli\u003eWidth: 482 mm, 19 \"\u003c\/li\u003e\n\u003cli\u003eDepth: 90 mm\u003c\/li\u003e\n\u003cli\u003eHeight: 44 mm, 1 U\u003c\/li\u003e\n\u003cli\u003eWeight: 1,96 kg\u003c\/li\u003e\n\u003cli\u003eGround lift switch: yes\u003c\/li\u003e\n\u003cli\u003eOperating voltage: 9 V\u003c\/li\u003e\n\u003cli\u003ePower consumption: 2 W\u003c\/li\u003e\n\u003cli\u003eAdditional Features: AoC output with ground lift, power LED\u003c\/li\u003e\n\u003cli\u003eAmbient temperature during operation: -20 - 70 °C\u003c\/li\u003e\n\u003cli\u003eRelative Humidity: \u0026lt; 80 %, not condensing\u003c\/li\u003e\n\u003cli\u003eAccessories (included): external power supply PW9V\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eAudio\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eMax. input level (\u0026lt; 1% THD, 20 Hz): + 14 dBu\u003c\/li\u003e\n\u003cli\u003eMax. input level (\u0026lt; 1% THD, 1 kHz): + 23 dBu\u003c\/li\u003e\n\u003cli\u003eMax. output level (\u0026lt;1% THD, 20 Hz - 20kHz): +19 dBu\u003c\/li\u003e\n\u003cli\u003eFrequency response (±0,5 dB, relative 1 kHz): 20 Hz - 20 kHz\u003c\/li\u003e\n\u003cli\u003eInput impedance (1 kHz): 390 kOhm\u003c\/li\u003e\n\u003cli\u003eOutput impedance (1 kHz): 110 Ohm(s)\u003c\/li\u003e\n\u003cli\u003eTHD + N (30 Hz, +4 dBu, unity, unweighted): \u0026lt; 0.0026%\u003c\/li\u003e\n\u003cli\u003eTHD + N (1 kHz, +4 dBu, unity, unweighted): \u0026lt; 0.0011%\u003c\/li\u003e\n\u003cli\u003eSNR (+4 dBu, 22 kHz BW, unity, unweighted): 105 dB\u003c\/li\u003e\n\u003cli\u003eIMD (SMPTE) (60 Hz \/ 7 kHz, 4:1, +4 dBu): \u0026lt; 0.0021%\u003c\/li\u003e\n\u003cli\u003eTransformer ratio: 1:3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Palmer","offers":[{"title":"Default Title","offer_id":43224154931279,"sku":"PAL-PBRIDGE4A","price":724.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0054\/9466\/9382\/files\/0893FAB4-A809-4C76-AF7A-94F8CC94D80A_-removebg-preview.png?v=1750694811","url":"https:\/\/shop.musicredone.com\/products\/palmer-bridge-4a-active-4-channels-di-box-19","provider":"RedOne Music Canada","version":"1.0","type":"link"}
