2.3. Setup Procedure

1. Connect the power cord into the AC Power Cord Connector.

2. Remove the Output Connector’s cover plate and connect the speakers to the output con-

nectors.

3. The dual RJ45 connectors allow a Primary & Secondary Ethernet port to the 100 Mbps

Ethernet network. Use the Primary or Secondary port and a Category 5 cable to connect to

the ACENet switch.

4. If using speakers higher than 8 ohms change the Mode Switch to 16/8, for most applica-

tions the mode switch can remain in the 8/4 setting.

Note: Ensure the amplifier is powered off before changing the mode switch.

The Channel Level Controls act as the overall master gain control for each channel in all

operational modes. As a starting point ASTi recommends that the Channel Level Controls

be set to the ‘10 o’clock’ position.

The Channel Level Controls are implemented rather counter-intuitively. With the ACENet

digital input active, and a setting of 12 o’clock (control vertically up), 0dB gain is applied

to the signal meaning a full-scale digital signal will demand full power from the amp. Set-

ting the control beyond 12 o’clock could cause clipping for any signal at or approaching

full-scale which is definitely not recommended. Using the 10 o’clock setting as the start-

ing point ensures clipping is not allowed and limits the amp to approximately 50 watts of

delivered power. If more power is required advance the control but do not exceed the 12

o’clock setting under any circumstance.

See section 3.2. Rear Panel Connections for more information.

The Input Connectors are not used in the ASTi system setup.

WARNING: Do not connect or disconnect speakers or ACENet while the amplifier is powered

on.
