ERCO by
Ferrum
The potentiometer built into the ERCO affects the volume of not only the headphones, but also the RCA
and XLR outputs (when Bypass is disabled). We recommend disconnecting headphones from the ERCO if
they are not used for a longer period of time, and especially if you want to control volume on RCA or XLR
outputs (when an amplifier or active speakers are connected). This practice can prevent excessive wear or
damage to your headphones.
6.3. Using ERCO with amplifiers or active speakers
The LED indicator (Fig.1D) on the front panel will change its color depending on the selected input or the
incoming data stream.
•
Green, Blue & Magenta
- MQA
The LED glows green to indicate that the unit is decoding and playing an MQA stream or file, and denotes
provenance to ensure that the sound is identical to that of the source material.
It glows blue to indicate it is playing an MQA Studio file, which has either been approved in the studio by the
artist/producer or has been verified by the copyright owner.
It glows magenta when ERCO is receiving MQA signal which is unfolded by some upstream decoder or
software where the media source is initially handled.
Note: For proper MQA decoding make sure your source can provide bit perfect signal to the ERCO. All
digital inputs will accept MQA signal.
•
Orange
- PCM
The LED will glow orange when any PCM data stream is detected.
•
White
- DSD
The LED will glow white when DSD or DoP data stream is detected.
•
Yellow
- Analogue input
The LED will glow yellow when analogue input is selected. There is no analogue signal detection so LED
will glow as long as analogue input is selected.
•
Flashing white
- Firmware loader mode
The LED will blink white when ERCO is in firmware loader mode.
•
Red
- Error / Fault
The LED will glow red when there is some kind of firmware/software error.
