[. . . ] GX212 Users Manual Version 1. 0 May 2001 ULTRATWIN ® ENGLISH ULTRATWIN GX212 SAFETY INSTRUCTIONS CAUTION: To reduce the risk of electrical shock, do not remove the cover (or back). No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electrical shock, do not expose this appliance to rain or moisture. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosure voltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] The EFFECT A and EFFECT B controls determine (with a few exceptions) the mix of original and effect signals. EFFECT A controls the left channel and/or the first effect (if combination effects are used), and EFFECT B adjusts the right channel and/or the second effect. As a rule of thumb, values between 20 % (moderate effect) and 40 % (clearly audible effect) should deliver good results. In the case of reverb and delay presets, the mix ratio is adjustable from 0 % through 50 % in steps of 1 %. 3. 1 Description of effects 01-02 Spring Reverb: Even a guitar amp with a digital multi-effects processor should allow you to use a spring reverb. This algorithm emulates the typical sound of a spring reverb, as it is known from numerous guitar amps. However, here you dont have the typical shatter sound when your amp gets knocked over. 03-04 Studio: This effect simulates the characteristics of middle-sized rooms. With its natural sound it can be used for a great variety of applications. 05-06 Chamber: You can clearly hear the sound as it bounces back from the walls of this room. The program is particularly suited for diffuse types of reverb or to make a dry guitar sound more natural. 09-10 Concert: Here, you can choose from a small theater (preset 9, short pre-delay) or a large concert hall (preset 10, long pre-delay). Compared to the STUDIO reverb program, these algorithms sound more lively and have more treble frequencies. A classic algorithm that makes your guitar sound wonderful and enchanting. 14 3.

Basically, the first variation uses a short predelay (delay until the actual reverb can be heard), while the second variation works with long pre-delays. In general, you can adjust the reverb time with the PARAMETER control, while the two EFFECT controls adjust the mix of original and effect signals in the left/right channel. 13-14 Gated Reverb: This reverb is cut off abruptly and became famous through Phil Collins In the air tonight. Use the EFFECT A control to adjust the threshold above which the reverb is triggered (Sensitivity). Density PARAMETER EFFECT A EFFECT B Gate/Reverb Time Sensitivity Mix Gate/Reverb Time Sensitivity Mix Tab. 3. 2: Parameters of effects 13 and 14 15-16 Ambience: The reverb of any room consists of so-called early reflections and the reverb tail. Since our ears use these reflections to determine the room size, they can be employed to create subtle and impressive reverb densities, without clouding the overall signal with long reverb tails.
