ERCO by 

Ferrum

Make sure the signal cables (optionally you can also connect an amplifier, active speakers, etc.) are 
connected to the ERCO before turning it on.

6.1.1. Setting gain switch for headphones

Set the Gain knob to the first position (-dB) and the Volume knob to about 25%.
Turn on the ERCO using the input selector - select either the Analog, USB, Optical or Coaxial input.
Now while listening to music, gently raise the volume using the Volume knob. If the volume is unsatisfactorily 
low at about 75% off, move the Volume knob back to 25% and the Gain knob to the second position (0). 
Repeat the procedure - gently raise the volume to about 75%.
If the volume is still noticeably low, move the Volume knob back to 25% and the Gain knob to the 3rd position 
(+dB). The idea is to set the optimum volume level with the Gain knob in such a way that you get the widest 
possible range from the Volume knob. Our recommendation is to find a Gain knob setting such that the 
optimum volume level is as close to 50% of the Volume knob as possible.

Note: The gain switch is only used to adjust the gain sensitivity for headphones. It does not affect the main 
outputs (XLR and RCA).

 6.1.2. Output priority

ERCO has been designed so that when headphones are connected to any of the headphone outputs, it 
turns off the main output (RCA and XLR). 
The 6.35 mm headphone jack has a higher priority than the 4.4 mm headphone jack - this means that if you 
connect two headphones to both outputs at the same time, only the headphones connected to the 6.35 mm 
jack will work.

6. GETTING STARTED

6.1. Using ERCO for the first time

The bypass function (Fig. 2G) disables the built-in potentiometer in ERCO. As a result, the signal given at the 
input of ERCO will be transmitted to the RCA or XLR outputs with all its power. This is useful when it is more 
convenient for the user to control the volume from the sound source.
The bypass function is disabled at the factory. To activate it you have to switch the rotary switch from 
position 0 to position 1 - the most convenient way to do it is with a flat screwdriver.

Please use the Bypass function with caution! A sudden jump in volume may damage your hearing and/or 
the speakers! Bypass function does not work for headphone output.

It is best to reduce the input signal at the source to a minimum before the Bypass function is activated.

Note: Ferrum refuses every liability for damage to equipment due to using Bypass function.
