Five effect categories — Robot, Megaphone, Vocoder, Harmony, and Reverb — each offer four distinct variations, enabling everything from sci-fi robot voices and vintage talk-box simulations to tight four-voice harmonies and lush reverb and delay effects. Eight scene memories allow instant recall of favorite configurations.\u003c\/p\u003e\n\u003cp\u003eThe rear-panel combo XLR\/TRS input accepts balanced microphone signals with up to +48V phantom power for condenser microphones, while a front-panel 1\/8-inch input with plug-in power accommodates lavalier and headset microphones. Dedicated real-time faders for Pitch and Formant enable expressive, continuous voice morphing without artifacts. A MIDI keyboard connected to the MIDI IN jack lets the Vocoder and Harmony effects track chords for dynamic, performance-triggered harmonization.\u003c\/p\u003e\n\u003cp\u003eThe VT-4 functions as a full 24-bit USB audio interface at sample rates up to 192 kHz, making it directly compatible with any DAW on Mac, Windows, or iOS via USB Type-B connection — no drivers required on most platforms. Power options include four AA batteries (≈4–7 hours depending on type and phantom power usage) or USB bus power from any USB port. 1\/4-inch TS line outputs (L\/MONO and R\/BYPASS) and a 1\/8-inch headphone output complete the connectivity.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e5 effect categories × 4 variations: Robot, Megaphone, Vocoder, Harmony, Reverb\/Echo\/Delay\u003c\/li\u003e\n  \u003cli\u003eReal-time Pitch and Formant faders for expressive voice morphing\u003c\/li\u003e\n  \u003cli\u003eRear combo XLR\/1\/4-inch TRS balanced mic input with +48V phantom power (10 mA max)\u003c\/li\u003e\n  \u003cli\u003eFront 1\/8-inch input with plug-in power for lavalier\/headset microphones\u003c\/li\u003e\n  \u003cli\u003eMIDI IN for keyboard-triggered Vocoder and Harmony effects\u003c\/li\u003e\n  \u003cli\u003e24-bit USB audio interface at 44.1, 48, 96, and 192 kHz; USB Type-B connector\u003c\/li\u003e\n  \u003cli\u003e8 scene memories for instant preset recall\u003c\/li\u003e\n  \u003cli\u003eBattery powered (4× AA, 4–7 hrs) or USB bus powered; Auto-Pitch hard-tune knob\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eMIC IN (Rear): Combo XLR \/ 1\/4-inch TRS phone, balanced; Phantom Power +48V \/ 10 mA max; Input Impedance 4.4 kΩ; Nominal Level –40 to –12 dBu (variable)\u003c\/li\u003e\n  \u003cli\u003eMIC IN (Front): Stereo 1\/8-inch (3.5 mm) miniature phone, plug-in power; Input Impedance 2.2 kΩ; Nominal Level –40 to –12 dBu (variable)\u003c\/li\u003e\n  \u003cli\u003eMIDI IN: 5-pin DIN connector\u003c\/li\u003e\n  \u003cli\u003eLINE OUT L\/MONO: 1\/4-inch TS phone jack, Nominal Level –10 dBu, Output Impedance 1 kΩ\u003c\/li\u003e\n  \u003cli\u003eLINE OUT R\/BYPASS: 1\/4-inch TS phone jack, Nominal Level –10 dBu, Output Impedance 1 kΩ\u003c\/li\u003e\n  \u003cli\u003ePHONES: Stereo 1\/8-inch (3.5 mm) miniature phone jack, Output Impedance 24 Ω\u003c\/li\u003e\n  \u003cli\u003eUSB Port: Type B\u003c\/li\u003e\n  \u003cli\u003eUSB Audio: 24-bit AD\/DA; Sampling Rates: 44.1 kHz, 48 kHz, 96 kHz, 192 kHz\u003c\/li\u003e\n  \u003cli\u003eEffects — ROBOT: Normal, Octave–1, Octave+1, Feedback\u003c\/li\u003e\n  \u003cli\u003eEffects — MEGAPHONE: Megaphone, Radio, BBD Chorus, Strobo\u003c\/li\u003e\n  \u003cli\u003eEffects — VOCODER: Advanced, VP, Talk Box, Spell Toy\u003c\/li\u003e\n  \u003cli\u003eEffects — HARMONY: +5, +3, +3\/–4, +3\/+5\u003c\/li\u003e\n  \u003cli\u003eEffects — REVERB: Reverb, Echo, Tempo Delay, Dub Echo\u003c\/li\u003e\n  \u003cli\u003eScene Memory: 8 presets\u003c\/li\u003e\n  \u003cli\u003ePower: 4× AA alkaline or Ni-MH batteries; USB bus power; Current Draw 500 mA\u003c\/li\u003e\n  \u003cli\u003eBattery Life: ~4–7 hours (varies by battery type and phantom power use)\u003c\/li\u003e\n  \u003cli\u003eWidth: 174 mm (6-7\/8 inches)\u003c\/li\u003e\n  \u003cli\u003eDepth: 133 mm (5-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003eHeight: 58 mm (2-5\/16 inches)\u003c\/li\u003e\n  \u003cli\u003eWeight: 554 g (1 lb 4 oz) including batteries\u003c\/li\u003e\n  \u003cli\u003eWhat's In The Box: Owner's Manual, Safety Leaflet, 4× AA Alkaline Batteries\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Roland","offers":[{"title":"Default Title","offer_id":46011690877125,"sku":"RLND-VT4","price":299.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0630\/3085\/3829\/files\/vt-4_main.jpg?v=1774908694","url":"https:\/\/avlgear.com\/products\/roland-vt-4-voice-transformer-vocal-effects-processor","provider":"AVLGEAR","version":"1.0","type":"link"}
