4- Turn the 

Output 

control clockwise until you can see 

level on the input of your recorder. Increase until the 
desired level is achieved. (

Vintage Hint

: Adjusting the 

Microphone / Line sensitivity control along with the 
Output control can provide a variety a different sounds 
by overdriving the amplifier circuits while lowering the 
final output level in order to not overdrive the recorder.) 
  
5- If you wish to connect the equalizer section to the 
line output of your board or D.A.W., simply connect to 
the female, Line Input XLR on the rear panel. 
  
6- When an electronic instrument such as an electric 
guitar is used, it may be plugged directly into the ¼” DI 
plug located on the front panel. Toggle the 

DI

 switch to 

select this input device. 
 
7- If phase reversal is needed, toggle the 

phase

 switch 

(a zero symbol with a diagonal line through it). 
 
8- To insert the equalization section into the circuit, 
toggle the 

EQ

 switch. Each section can be set to OFF 

with the 

frequency selector

 knob. As you add or 

subtract gain within the equalizer, be sure to adjust your 
overall gain with the 

output 

control. When the 

output

 

control can no longer make the adjustments that you 
need, you may switch to a higher or lower gain setting 
on the 

Microphone / Line sensitivity

 control.
