OUTPUTS
The OUTPUTS deliver balanced output signals. An output trans former can be equipped
optionally (see page 29).
Since both connectors are working in parallel, unbalancing one connector also unbalances
the other one. If for example a mono jack connector is plugged into to the jack socket, the
XLR socket is operating unbalanced as well. Depending on the impedances of the connected
devices, a parallel use of both outputs can reduce the signal level. Therefore, we recommend
to use either the XLR or the 1/4" TRS output socket.
A/D INPUT 2
The Channel One is a mono channel strip, but the optional A/D converter card 2376 is a dual-
channel device. Therefore a second (external) signal can be converted with the converter
card, if it is connected to the AD INPUT 2. If no signal is connected to the A/D INPUT 2, the
output signal of the Channel One is routed to both converter channels. The maximum input
level for the converter is +12dBu (=0 dBFS).
PLAYBACK INPUTS
The playback signal is connected to the unbalanced PLAYBACK INPUTS to create a head-
phone moni toring mix. If a mono playback signal is available, only the LEFT connector must
be connected. The signal will then be present on both channels. The RIGHT connector should
be used if only one channel should appear on one side of the headphones. In contrast to all
other connectors the PLAYBACK INPUTS are unbalanced.
POWER
The front panel POWER switch activates the unit, confirmed by the illuminated switch.
Switch on the unit only after you have checked the correct setting of the rear VOLTAGE
SELECTOR and 48V phantom power supply front switch.
When you activate the Channel One, the unit commences the warm-up mode to heat the tubes.
The warm-up cycle takes between 15 and 30 seconds. The WARM UP LED in the display area
illuminates during warm-up mode and the Channel One is ready to operate when the WARM UP
LED turns off.
