1.0 Introduction
Note: This document only pertains to Ashly Power Amplifiers and ASTi equipment. For gen-
eral information about the Ashly Power Amplifier, go to Ashly.com.
The Ashly Power Amplifier drives four to eight passive audio loudspeakers. Each amplifier is a
network device that integrates with ASTi’s Audio Communications Environment Network
(ACENet). ACENet provides a low-latency, network-based audio and I/O distribution archi-
tecture for ASTi’s Telestra and Voisus platforms. The amplifier also offers a full range of indic-
ators for accurate diagnostics. This document provides an overview of the ne8250c eight-
channel amplifier.

2.0 Getting started
Important: Before installation, unplug the amplifier, and turn down the channel attenuators
on the front panel.
This chapter discusses the following topics:
lCooling
lSet up an Ashly Power Amplifier
2.1 Cooling
Do not block any of the amplifier ventilation vents. When using an equipment rack, mount the
units directly on top of each other. Do not block rear, front, or side air vents. The side walls of
the rack should be a minimum of one inch (2.5cm) away from the amplifier sides, and the back
of the rack should be open.
2.2 Set up an Ashly Power Amplifier
Figure 3, "Ashly Power Amplifier rear panel" below shows the Ashly Power Amplifier's rear
panel:
Figure 3: Ashly Power Amplifier rear panel
To set up an Ashly Power Amplifier, follow these steps:
1. Use the first or second port and a CAT5 cable to connect to the ACENet switch. Do not
connect both.
2. Connect the 10/100 Ethernet port to the ACENet switch.
3. Connect the alternating current (AC) power cord.

4. On the front panel, turn the channel attenuators all the way down.
5. Turn on the Power switch. The power indicator illuminates after a short boot-up
sequence.
6. After connecting the amplifier to the network, set up the amplifier on ACENet in the
Telestra Remote Management System.
Important: Disconnect the power cord before making any change to the installation or wir-
ing.
The analog input connectors are not used in the ASTi system setup.
Caution: Do not connect or disconnect speakers or ACENet while the amplifier is on.
