No sir, Valvetronix is the real deal - the best of both worlds. VALVE REACTOR TECHNOLOGY: THE POWER (AMP) AND THE GLORY! n

27、keeping with Voxs brave, pioneering spirit, the Valve Reactor circuitry that drives the power amp in your new VOX combo is a groundbreaking piece of technology. Without getting overly technical, heres whats going on. While much of the tone creation and shaping carried out in this amp is done in the

28、digital domain, its Valve Reactor power amp is 100% analogue. The resulting journey your guitars signal takes through the analogue world of the power stage plays a major role in providing the all-important feel and tone of the original amps we modeled. The Valve Reactor power stage is, to all intent

29、s and purposes, a bona fide valve (tube) push-pull power amplifier, but in miniature. It utilizes a 12AX7 valve (a dual triode device - meaning “two valves in one”) and is equipped with an output transformer, just like a “real” valve amp. Instead of connecting directly to the loudspeaker though this

30、 transformer is connected to a specially designed VariAmp Power Circuit that increases the magnitude of the transformer output from its lowest level (1 Watt) up to the maximum output of 60 Watts per channel. Because VariAmp Power Circuit stage is completely transparent (doesnt colour or change the s

31、ignal in any way), the resulting output tone is pure valve. It also ensures that the output signal maintains the high dynamic range associated with traditional valve amps - something most solid-state amplifiers cannot deliver, and one of the main factors why valve guitar amps normally sound and feel

32、 so much louder and more alive than a solid-state amp boasting the same output power. What is ? (Resonant structure and Electronic circuit Modeling System) is KORGs propri- etary sound modeling technology which precisely reproduces the complex character and nature of both acoustic and electric instr

EXTERNAL SPEAKER OUT Jack(s) This is where you can hook up external speaker cabi

34、net(s) if youd like to. The AD60VT has one (1) EXTERNAL SPEAKER OUT jack, while the AD120VT has two (2). Why does it have two? Because the AD120VT is a stereo amp! IMPORTANT NOTE: The internal speaker(s) in your Valvetronix combo remain con- nected when external speakers are connected. For optimum p

35、erformance we strongly advise the following: 1. Only use extension speaker cabinets of 8 Ohms impedance or less (e.g. 4 Ohms) with these combos. And, if youre using a stereo cabinet with the AD120VT make sure each side (Left lets get back to the wondrous workings of the ORIGINAL VALUE LED. As mentio

36、ned earlier when we were going through the Top Panel of your amp, the ORIGINAL VALUE LED also acts as the indicator for the BYPASS Button which, when engaged, bypasses the MODULATION, DELAY and REVERB sections of the amp. So, as youd expect, when the BYPASS Button is activated, the ORIGINAL VALUE LE

37、D lights up, and stays lit until the BYPASS is switched off again. So, the ORIGINAL VALUE LED is either “off” or “on.” If its “off” it will light up for a second when an original value is found. Likewise, if its “on” it will turn off for a second when an original value is found. Log- ical enough, ri

38、ght? Good, now thats loud n clear, lets get on to the business of finding out exactly whats dialed in on a particular program. To make life easier, lets start at the far left of the Top Panel and work our way through it. First up is the PEDAL Section. STEP 1: Look at the LED in the top left hand cor

39、ner of the PEDAL Section. Is it lit up? If it is it means a pedal is being used so go to STEP 2. If it isnt lit up, skip to STEP 5. STEP 2:So, the PEDAL LED is on, meaning a pedal is being used - lets find out which one. Simply keep your eye on the ORIGINAL VALUE LED and slowly click through the 10

40、pedal model choices. When you reach the one thats being used the ORIGINAL VALUE light will either go on or off for a second, depending on whether the BYPASS button is engaged or not. Like I said, simple stuff. 27 STEP 3:Now that weve found which PEDAL is being used, lets find where the DRIVE Control

41、 for it is set. So, watch the ORIGINAL VALUE LED and slowly but surely sweep the DRIVE Control through its full range of motion. When you reach the setting, the ORIGINAL VALUE LED will tell you. STEP 4: Do the same thing with the LEVEL Control in the PEDAL Section. STEP 5: The AMP SECTION is next. L

42、ets find out what models being used by slowly clicking the AMP TYPE Selector Switch through the 16 choices while keeping an eye on the ORIGINAL VALUE LED. When you reach the one thats being used the ORIGINAL VALUE light will either go on or off for a second, depending on whether the BYPASS button is

43、 engaged or not. Wow, easier than falling off a log isnt it? And far less painful too! STEP 6:Right, weve found the amp model, now lets figure out where each of the programmable amp controls are set - namely, GAIN, VOL- UME, TREBLE, MIDDLE, BASS and PRESENCE. Lets start with GAIN and move right, one

44、 knob at a time.and you already know what to do, right? Yes, youve got it - slowly but surely rotate the GAIN control through its full range of movement while keeping an eagle eye on our helpful pal, the ORIGINAL VALUE LED. When you reach the setting, the ORIGINAL VALUE LED will let you know. STEP 7

45、:Do exactly the same for the VOLUME, TREBLE, MIDDLE, BASS and PRESENCE controls.duh! STEP 8:So, weve already done the Pedal and Amp Sections, now all thats left are the three sections in our “virtual effects loop” - MODULA- TION, DELAY and REVERB. Lets start with MODULATION - ignoring the EX CTL LED

46、, is an LED lit up in this section? If an LED is “on” it means the effect its next to is being used so we need to find out where the SPEED and DEPTH controls are set for the effect in question. And you know what to do by now when it comes to finding the “original setting” for a control knob dont you!? So star
