EVM Description

1.3

Initial Power Up

Before applying power, check to make sure the standby control switch is in the Standby OFF position, as
shown in

Figure 2

.

Figure 2. Front Panel Labels

Apply power: the Standby, Mute, and Power LEDs should be on. This indicates that the unit is powered,
and the TAS5514B is in Standby Mode. The TAS5514B is place into play mode by simply moving the
toggle switch to the Standby OFF position. The Fault LED may flash once and then go off. This is the
device automatically clearing the faults at startup.

Description of Inputs

2.1.1

Analog Inputs

The TAS5424B EVM provides balanced input and the TAS5514B EVM provides unbalanced (single-
ended) inputs. The four RCA jacks on either EVM are provided for the audio input. The unbalanced inputs
have the shield of the RCA connected to ground. The balanced inputs have the plus (+) input on the
center pin of the RCA and the minus (–) input on the shield. The balanced ground can be connected to
the chassis or Power– (GND).

2.1.2

Power

The EVM requires one dc power connection. The connection is made through a 10-pin supplied
connector. The black wire is ground and the red wire is connected to PVDD, which can range from 6 to 24
Vdc.

2.2

Description of Outputs

2.2.1

Speaker and Power Connections

The 10-pin connector on the EVM and the wiring harness provide the power connections and the speaker
connections. The power connection consists of a pair of red and black twisted wires, which correspond to
the plus (+) input and minus (–) input, respectively. This pair of wires must be attached to a power supply.

The speaker connections consist of the remaining four pairs of red and white twisted wire. Each pair of red
and white wires corresponds with a channel. The red wire corresponds to the plus (+) output, and the
white wire corresponds to the minus (–) output. These wires must be terminated to a speaker load or
resistive load.
