Rear Panel Connectors

• Analog In (DB-25-F): This connector accepts balanced, low

impedance, line level analog signals. See Figure 2–4 below for pin-

out information.

Input Connectors

• Power: Attach a standard IEC-320 power cord between this

connector and AC mains power.

• AES/PCM In (1 through 4, BNC-F): These connectors accept

unbalanced (75 Ω) PCM (AES/EBU) formatted signals. These inputs

appear as AES1

AES1AES1

AES1 in the LCD screen.

If you are not connecting downstream equipment, then you should

terminate the selected input connector. Otherwise, unterminate

them.

• AES/PCM In (and Loop Out) (DB-25-F): This connector accepts

balanced (110 Ω) AES signals. Inputs are internally connected to the

loop-through outputs. These inputs are referred to as AES2

AES2AES2

AES2 in the

LCD screen. If you are connecting downstream equipment to the

AES loop-through outputs of this connector, then you should

unterminate this connector. If you are not connecting downstream

equipment, then you should terminate them. Refer to Terminating/

Unterminating Inputs on page 35 for details.

Note:

The pin-out for this connector is compatible with

Tascam DB-25 to XLR cable assemblies. Contact your

Wohler sales representative for availability. (Wohler’s

contact information is on page ii of this document.)
