Operation And Usage; Channel Routing Aeb4-I; Pin Assignment Of The Trs Jacks - RME Audio AEB4/8-1 User Manual

7. Operation and Usage

Switch on the computer and boot the OS. The green LED on the AEBx-I is lit when the power
supply is present.
DIGI96 series
Start the Settings dialog of the DIGI96/8 series, select the internal input (Input 'Internal'), set
Clock Mode to 'Master'. The Input Status must now show 'ADAT, 44.1 kHz, Internal' (or 48
kHz). In case 'No Lock' is shown either the sample rate at the card's output is below 44.1 kHz
(see Output Status), or the AEB is not connected correctly.
Hammerfall series and HDSP 9652
Start the Settings dialog of the Hammerfall, select the internal input (AEB 'ADAT1 Internal'), set
Clock Mode to 'Master'. The Input Status in the field SyncCheck must now show 'ADAT1 In
SYNC'. In case 'Lock' or 'No Lock' is shown either the sample rate at the card's output is 32 kHz
(see Sync Ref., Freq.), or the AEB is not connected correctly.
Note
The AEB gets its clock directly from the output of the DIGI card. To avoid a clock loop the card
has to be set into 'Master' mode.

8. Channel Routing AEB4-I

The AEB4-I copies all 4 analog input signals to the corresponding channels 5-8. Therefore for
example the first two channels can also be recorded using the wave device 5/6.

9. Pin assignment of the TRS jacks

The analog inputs are accessible through stereo ¼" TRS jacks.
The AEB4-I is fitted with electronically balanced, single channel inputs (+ = tip). The servo
balanced input circuit allows to use monaural TS jacks (unbalanced) with no loss in level.
The AEB8-I is fitted with unbal-
anced stereo inputs. Use an
adapter TRS plug to coaxial
(phono) plugs, or TRS plug to TS
plugs (see drawing to the right) for
connection to external equipment.
We recommend to use so called
'insert' cables.
The pin assignment follows interna-
tional standards. The left channel is
connected to the tip, the right chan-
nel to the ring of the TRS jack/plug.
