The top of the Babyface features a rotary encoder with push switch function, 2 keys, 2 LED
bands and 5 status LEDs.
The two LED bands show the current gain, the input or output level, or indicate the channel to
be set, all dependent on the current mode. The lowest LED signals phantom power (+48 V,
orange), the highest one overload (Clip, red).
The rotary encoder is used to change various parameters directly at the unit. First the left key
Select is used to select the mode which is then displayed by the Status LEDs:
¾ Input: Setting the gain of the analog stereo inputs. A
push on the encoder changes between left, right or
both.
¾ Output: Setting the output level of the analog outputs
1/2 at the breakout cable. A push on the encoder
activates Dim for the Main Out defined in TotalMix FX
(default: Analog 1/2).
¾ Phones: Setting the output levels of the analog
outputs 3/4. A push on the encoder activates Dim for
the Main Out defined in TotalMix FX (default: Analog
1/2).
¾ Sync: Synchronisation indicator for the digital optical
input (SPDIF, ADAT). Flashes when the signal has
been detected but is not fully synchronous. See also
chapter 9.9 / 16.2, Clock Modes - Synchronisation.
The key Recall is used to store and load a specific listening volume for the Main Out (default:
Analog 1/2) defined in TotalMix FX. Pushing the knob for 2 seconds stores the current setting. If
the volume (output level) had been changed a quick hit on the Recall key will restore the former
value.
The right side of the Babyface has an instrument input and a
headphones output.
The analog input 2 can be switched in TotalMix between line (low
impedance, balanced, at the breakout cable) and instrument (high
impedance, unbalanced, TRS jack at the unit). See Settings menu
of input channel 2.
The analog outputs Phones (channels 3/4) are available at the breakout cable and on the right
side of the unit. The connectors are not separated electrically. When connecting two head-
phones the volume might be reduced. The low impedance and unbalanced output signal is – in
terms of quality – identical to the ones at the line outputs, but limited to +7 dBu.
In case the phones output is to be used as line output, usually an adapter TRS plug to RCA
phono plugs, or TRS plug to TS plugs is required. More on cable codes and pinouts can be
found in chapter 27.2.
