{"product_id":"ssl-500-series-vhd-preamp","title":"500-Series VHD+ Preamp","description":"Solid State Logic, a world leader in creative tools for audio professionals, has introduced the new VHD Pre module for the 500 series format, designed for popular and practical modular rack systems. The product finally brings the versatile preamplifier technology found in the Duality console, the flagship of SSL's line present in major studios worldwide, within reach of studios of all sizes. The VHD Pre is a very versatile device for recording and processing stages: this module guarantees the ultra-clean sound of SSL SuperAnalogue™ preamplifiers but also features VHD - Variable Harmonic Drive mode, SSL's patented system that, through a 100% analog signal path, is capable of generating rich harmonic distortions. By increasing the input gain, the VHD circuit progressively introduces a 2nd or 3rd order harmonic distortion, or a combination of the two. At lower gain levels, VHD adds a slight harmonic distortion that warms the source in an extremely 'soft' way, mimicking the behavior of a classic tube or transistor circuit. As the gain increases to extreme values, the distortion becomes greater, leading to more pronounced effects for grunge sounds typical of transistors. The VHD Pre offers the user the maximum versatility of a studio-quality preamplifier: whether you're looking for the typical ultra-clean sound of traditional SSL consoles, a subtle tube or transistor distortion, or gradually moving towards total distortion effects, VHD will change normal expectations of what a preamplifier is capable of.The VHD section of the VHD Pre module has three rotary controls: - Drive selects the type of harmonic distortion, varying between 2nd and 3rd harmonic and blending between the two. - Gain controls the input gain with a range between +20 and +75dB. - Trim adjusts the output level (-20 \/ +20dB) for perfect level matching with other devices, as the VHD circuit by its nature can significantly amplify the signal.The VHD Pre module offers other features for studio use: an LED for signal presence, an adjustable High-Pass Filter (HPF) between 15Hz and 500Hz, Hi-Z selector for perfect impedance matching with any microphone, +48V phantom power, PAD for use with line-level signals, and a phase inversion switch.Key features:• SuperAnalogue™ series preamplifier used in the Duality• VHD control that simulates variable 2nd and 3rd order harmonic distortion• Variable LF Filter from 15Hz to 500Hz• Hi-Z switch for high-impedance sources• +48V Phantom Power with status LED• PAD for use with line-level sources• Phase inversion switchSSL VHD technology is available in the following products: Duality, XL-Desk, VHD Input X-Rack Module, and the VHD Pre (1U rack).","brand":"Solid State Logic","offers":[{"title":"Default Title","offer_id":53994108846413,"sku":"729731X2","price":616.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/vhd-pre-per-serie-500_f.png?v=1784732083","url":"https:\/\/musicdelivery.net\/en\/products\/ssl-500-series-vhd-preamp","provider":"Music Delivery","version":"1.0","type":"link"}
