1. OVERSAMPLING Act NE 1 12 ZER VOLUME FEEDBACK OUTPUT MODE CAB STEREO User Manual Copyright O 2014 Shattered Glass Audio a division of Creative Bytes Inc Introduction Ace TM is designed to emulate the legendary 1950s 5W all tube tweed covered amp The original circuit shown in Figure 1 has one 12AX7 dual triode in the preamplifier section and a single 6V6GT power tube The amp has only a volume control located between the first and the second preamp stage and no tone controls 100k 0 024 100 k 0 02 u 12AX7 220k Figure 1 Amplifier Schematic Every component and interaction between components in the signal path has been accurately modeled Since the original amp has a small 6 speaker we have used an impulse response of a small speaker for the cabinet emulation By using an impulse response of a small speaker for cabinet emulation we have preserved the natural bass roll off aconsequence of inability of a small speaker to faithfully reproduce bass frequencies To make Ace more versatile we have added to the model two of the most common amplifier mods removal adjustment of the amount of feedback and addition of grid stopper resistors The amount of feedback directly influences the gain whereas grid stoppers among other things mediate the blocking distortion Ace s conservative CPU usage makes it suitable for live performance uses System Requirements This plugin is available in both 32. 2 and 64 bit VST and AU versions AU version is available for Mac only Mac OS X 10 7 or higher Ace is a trademark of Creative Bytes Inc Windows XP 7 8 User Interface Figure 2 shows Ace s control panel A 6 7 A e ZUM f 3 10 oo 12 dB i ZER ZER MAX a OFF po OFF INPUT VOLUME FEEDBACK OUTPUT MODE 1 STEREO Figure 2 Ace controls panel Settings controlled by knobs can be changed by clicking on them and dragging the mouse up and down Settings controlled by switches can be changed by clicking on the appropriate switch or by clicking a switch and dragging the mouse Controls Input Controls the input gain and therefore the strength of the input signal Volume This control corresponds to the Volume knob on the amp Feedback Feedback allows you to adjust the amount of feedback in the original circuit The amount of feedback can be adjusted from ZERO to FULL ZERO setting corresponds to no feedback whereas FULL corresponds to the amount of feedback in the 5E1 circuit i e the original feedback Output This control lets you adjust the output level of the whole plugin Oversampling Select 2 4 or 8 times the original sampling rate Mode Mode control allows you to choose between the original 5E1 circuit and the 5E1 circuit modified to control the blocking distortion Mode A corresponds to the original 5E1 circuit whereas the mode B corresponds to the circuit with grid s
3. toppers added to control the blocking distortion Cab This control allows you to bypass the cabinet emulation To bypass the cabinet emulation set the CAB switch to OFF Stereo Stereo control lets you switch between mono and stereo processing To set processing to mono set the STEREO switch to OFF Stereo processing nearly doubles the CPU load of the plug in when compared to mono processing since in the stereo mode the plug in needs to process two channels compared to one channel in the mono mode
