{"product_id":"toa-l-01f-600-ohm-balanced-line-matching-input-module-for-900-series","title":"TOA L-01F 600-Ohm Balanced Line Matching Input Module for 900 Series","description":"\u003cp\u003eThe TOA L-01F is a plug-in line matching input module that gives a TOA 900 Series mixer\/amplifier a true 600-ohm, transformer-isolated balanced line input terminated on a female XLR connector. Transformer isolation is what sets this module apart from an ordinary line input: it galvanically separates the source from the amplifier, breaking ground loops and rejecting the common-mode hum that long cable runs pick up in a commercial building. Where a background music source, a telephone paging interface, an assistive listening transmitter or a legacy broadcast feed expects to see a 600-ohm load, the L-01F provides the correct matching impedance instead of forcing the source into a mismatch.\u003c\/p\u003e\u003cp\u003eThe module drops into any of the eight input ports on TOA's 900 Series hosts, including the A-903MK2, A-906MK2 and A-912MK2 mixer power amplifiers and the M-900MK2 mixer preamplifier, as well as the six ports on the W-906A and W-912A in-wall mixer power amplifiers. It is equally at home in the two dedicated 900 Series module slots built into TOA's 800D Series digital mixer amplifiers (A-812D, A-824D and A-848D), and in the 9000M2 Series amplifiers, which TOA specifies as accepting existing 900 Series input modules alongside newer 9000 Series cards. Installation is a front-panel swap: pull the blank, seat the L-01F, and the port becomes a balanced 600-ohm line input.\u003c\/p\u003e\u003cp\u003eElectrically the L-01F is deliberately simple and clean. Rated input sensitivity is -18 dB for the amplifier's -20 dB rated output, and frequency response runs 20 Hz to 20 kHz within ±1.5 dB, so program material passes through without coloration. Because the input is transformer-isolated rather than electronically balanced, the L-01F is the module to reach for in retrofit and mixed-vintage systems, in buildings with noisy electrical services, and any time a line source has to travel a long distance to the rack. It is a standard specification item for schools, houses of worship, airports, hospitals, factories and retail paging systems built around the TOA 900 Series platform.\u003c\/p\u003e\u003ch2\u003eFeatures\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLine matching input module for TOA 900 Series mixer\/amplifiers and mixer preamplifiers\u003c\/li\u003e\n\u003cli\u003eTransformer-isolated 600-ohm balanced input for applications requiring true 600-ohm line matching\u003c\/li\u003e\n\u003cli\u003eFemale XLR connector (XLR-3-31 equivalent) on the module face\u003c\/li\u003e\n\u003cli\u003eTransformer isolation helps break ground loops and reject common-mode noise on long runs\u003c\/li\u003e\n\u003cli\u003eWide, flat 20 Hz - 20 kHz response for full-bandwidth music and speech\u003c\/li\u003e\n\u003cli\u003ePlugs into 900 Series hosts (A-903MK2, A-906MK2, A-912MK2, M-900MK2, W-906A, W-912A), the two 900 Series module slots on 800D Series amplifiers (A-812D, A-824D, A-848D) and 9000M2 Series amplifiers\u003c\/li\u003e\n\u003cli\u003eCompact plug-in format installs from the front panel without rewiring the amplifier\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eModule type: Balanced line matching input module (900 Series)\u003c\/li\u003e\n\u003cli\u003eInput sensitivity: -18 dB (0 dB = 1 V); rated output -20 dB\u003c\/li\u003e\n\u003cli\u003eInput impedance: 600 ohms, balanced, transformer-isolated\u003c\/li\u003e\n\u003cli\u003eFrequency response: 20 Hz - 20 kHz, ±1.5 dB\u003c\/li\u003e\n\u003cli\u003eConnector: Female XLR (XLR-3-31 equivalent)\u003c\/li\u003e\n\u003cli\u003eModule dimensions: 35 (W) x 78 (H) x 88 (D) mm \/ 1.38\" x 3.07\" x 3.46\"\u003c\/li\u003e\n\u003cli\u003eModule weight: Max. 110 g (0.24 lb)\u003c\/li\u003e\n\u003cli\u003eShipping weight: 0.2425 lb\u003c\/li\u003e\n\u003cli\u003eShipping carton: 3.54\" x 3.74\" x 1.57\"\u003c\/li\u003e\n\u003cli\u003ePhantom power: Not provided on this module\u003c\/li\u003e\n\u003cli\u003ePower supply \/ current consumption: Not published by TOA for this module\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e1x TOA L-01F 600-ohm balanced line matching input module\u003c\/li\u003e\n\u003cli\u003eNo additional accessories are specified by TOA for this module\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOA Electronics","offers":[{"title":"Default Title","offer_id":46588272017605,"sku":"TOA-L01F","price":117.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/L-01F_Angle.jpg?v=1784921210","url":"https:\/\/avlgear.com\/products\/toa-l-01f-600-ohm-balanced-line-matching-input-module-for-900-series","provider":"AVLGEAR","version":"1.0","type":"link"}
