Front Panel Features

$Power-Dynamics-PDA-B500-PDA-B-Series-Professional-Power-Amplifier-FIG- $1$$

Cooling Vents.
Front to rear forced airflow.
Volume Controls.
These controls adjust the volume level of both channels. Turn slightly to the left when the clip indicators (4) light up.
Protect Indication.
When on any given point, something damaging might occur to your amplifier, it will switch in protect mode. The amplifier will disconnect the point where the damage is about to occur and switch on the protection led to indicate to you that something is wrong. Reasons might be: Bad ventilation,
A low impedance (< 4 Ohm), Defect fan(s), A short circuit in cables.
Clip Indication.
These LEDs will light up when one or both channels are on max power. It can occur that these LEDs will lit up now and then, this is not a problem. But if it lights up continually you need to adjust the volume down, otherwise permanent damage to equipment might occur
Signal indicators.
Green LEDs indicate the amplifiers output signal levels.
On/Off Switch.
For switching the amplifier on and off. Always adjust the volume down to its minimum before switching this amplifier on.
Blue LCD display
Information of the operation mode and parameters.
LOAD 4/8 Ohm
Select the speaker load for the correct calculation of the output power.

DISPLAY

Standard indication:

Line-1: The output power of both output channels. The amplifier calculated the output power. NOTE: Select the correct load impedance (button 8) Calculation not 100% correct in bridge operation.
Line-2: If CLIP ON the amplifier input/output is overloaded. Reduce in that case the input level.
Line-3: Protection information.

Mode Switch.
- The amplifier can use 2 different modes: stereo or bridge. Choose one of these functions:
- Stereo mode: Standard left/right stereo mode.
- Bridge mode: This mode combines both amps on one channel which results in double power on this channel. Connects the signal to the left input channel and the output level can now be adjusted with the left volume control.
Ground Lift Switch.
Allows circuit and chassis grounds to be separated in case of problems with earth loops (hum).
Balanced 6.3mm Stereo Jack inputs. Two 6.3mm jack female input connectors for connecting a signal source (mixer etc.).

Installation

Connecting Input
Both inputs are balanced. If a balanced output is unavailable, you can also use an unbalanced one, and connect pin 3 – with pin1 mass (see below). The unbalanced line may result in noise over long cable runs.

1= earth / mass, 2=signal +, 3=signal –

Connecting Output

Make sure the amplifier is turned off before you wire the system. Speakers can be connected using speaker NL4 plugs or bare wire for your binding post output connectors. Using the guidelines below select the appropriate size of wire based on the distance between the amplifier and speaker.

Distance/Wire Size

<10m 1.5mm2
10m <20m 2.5mm2
20m <30m 4.0mm2

NOTE: Never connect a hot (+) output to ground or (-) output and never connect the hot (+) to other hot outputs!

Connect to mains power

Before plugging the unit in always make sure that the power supply matches the product specification voltage. First, connect the IEC end of the cordset to the IEC connector on the amplifier then plug the other end of the cordset to the AC mains.

Please read the instructions below for reliable and problem-free use:

Be sure all connections made are made in the correct way.
Check if the connected speakers are compatible with the amplifier.
Ensure there is adequate ventilation.
Prevent exposure to moisture.
Never plug speakers in/or out while in use, this can result in serious damage.
