MICROPHONE Studio Projects C1 Studio Condenser NOTE: Plugging into the Insert Jack interupts the normal signal flow thru the VTB-1. If the jack is not wired with the TIP and RING tied together, no signal will show on the meter (OUT) or be present at the Bal Out or Line Out of the VTB-1. NOTE: Microphone input shown, but this setup works the same way for Line-In signals. Use the front-panel jack and switch to bring instruments into the VTB-1. 12VAC Balanced Out Line Out Insert SLEEVE RING TIP 200 Mic In Tip=Send Ring=Return 50 Mic Impedance VTB-1 REAR CONNECTIONS Line In 20 Input Gain 25 30 40 6 0 60 50 HPF Tube Blend 1 2 = 1 2 3 4 Meter Level -20 -8 0 +8 +15 Output Level ­ 0 + 6 6 48 Volt Line In 70Hz 3 4 Output Input Pol Rev Studio Projects INPUT GAIN: CONTROLS THE LEVEL OF BOTH OUTPUTS HI-PASS FILTER: AFFECTS SIGNAL GOING TO BOTH OUTPUTS SS Tube Tube Mic Pre · 12 VTB-1 FRONT CONTROLS TUBE-BLEND: ONLY AFFECTS THE ENHANCED OUTPUT.

The meter may stay in its lower ranges when driving semi-pro gear (-10dBV levels). If your equipment has a level-select switch, set it for +4 operation for best results and quietest operation. Because of its specially designed signal path, the VTB-1 can be used to generate two distinct outputs by using its Insert Jack as an additional output. The insert point is after the HPF, but directly before the Blend Control. The signal feed from the insert jack is before any tube circuitry, so the additional output will always be a SS only signal. The insert cable needs to be wired as a "Borrow Cable" by tying the Tip and Ring connections together. This allows the insert signal to feed the outside world but still continue through the VTB-1 in its normal way. By using the Blend control, the user can add the desired amount of Tube Sound to the main (Enhanced) outputs while still having a clean, all solid-state output also available. STUDIO PROJECTS VTB-1 HOOKUP DIAGRAM Using the VTB-1 for generating two different sounding feeds. Using the VTB-1's Insert jack, a clean (all SS) signal, as well as a Tube Sound signal, can be simultaneously generated.

If the Ext Gear is OFF, or its output is muted, no signal will show in the meter (OUT) or be present at the Bal Out or Line Out of the VTB-1. [. . . ] The Insert Jack is a 1/4" TRS jack and is wired as Tip= Insert-send, Ring= Insert-return, Sleeve= Ground. When a compressor is being used, use the Meter (IN) to monitor the internal level and use the Gain control to set the SS preamp to a conservative level (keep levels below 0 on the meter). Then use the controls of the external compressor to keep the dynamics within the desired range.
