Features

• Audiophile Design: Sophisticated design and superior internal components ensure outstanding sound quality, performance, and long-term reliability.
• Advanced Protection: Each channel is individually protected. If a channel requires shutdown for protection, only that channel is affected, allowing others to continue playing. It will automatically return to normal operation once conditions are resolved.
• Flexible Input Selection: Each of the 8 channels can be assigned various source inputs, including dedicated inputs, or configured to play common signals from the Bus or Auxiliary inputs, offering flexibility for custom audio installations.
• Bridging: Adjacent channels can be combined to provide increased power output for specific areas, easily achieved with a single switch.
• Individual Channel Level Adjustments: Each channel features its own level adjustment, allowing precise matching of speaker loudness to its respective area.
• Multiple Power Modes and Output Trigger: Offers three ways to turn the amplifier ON: constant, trigger, and audio sense, enabling seamless integration into sophisticated custom installations. A separate output trigger can activate other components via voltage trigger.

• 12-15V AC/DC Input (14): Triggers power-up from an external voltage source, such as a receiver.
• Speaker Channel Output Binding Posts (15).
• Speaker Channel Bridged Mode Binding Posts (16).
• 3-Prong Removable Power Plug (17).
• Fused AC Input (18).

System Design & Operation Considerations

Understanding these terms is key to system design and operation:

• Multi-Room: Plays the same source simultaneously in all rooms. Changes made in one room affect all others. Volume can be controlled separately per room using volume controls or speaker switchers.
• Multi-Zone: Allows different sources to be played in each room independently.
• Bridging: Combines two channels to create a single mono channel, useful for increased volume in a specific area.
• Source: Any component (CD, VCR, DVD, tape deck, tuner) providing an audio signal to be amplified.
• Channel: A distinct unit of the amplifier providing output to one speaker. Inputs can be configured to BUS, AUX, or dedicated CHANNEL INPUT. Adjacent channels can be bridged for higher power.
• Level Controls: Independent adjustments for each channel's output level to balance sound across different rooms or areas.

Diagram 3: Power Mode Selection

This diagram illustrates the power mode selection options:

• 12-15V AC/DC TRIGGER INPUT: Connects to an external voltage source for trigger-based power-up.
• 12V CONTROL OUTPUT: Provides a 12V DC output to activate other components.
• Mode Switch: Selects between AUDIO SENSE and CONSTANT modes.
• 2.1mm x 5.5mm Power Input Jack: For standard power connection.
• 3.5mm Power Output Jack: For the 12V control output.

System Design Examples

The following examples illustrate typical configurations for the PT8000CH amplifier:

• Multi-Room Installation (Diagram 4): Distributes a single audio source to all rooms. The Input Selection switch is set to "BUS" on all channels, with adjacent channels assigned left and right for stereo output.
• Multi-Zone Installation #1 (Diagram 5): Provides independent audio signals to different zones. Zone 2 uses a dedicated CD player input, while Zone 1 connects to the preamplifier/receiver via "BUS" inputs on channels 1-10 (assigned left/right) and "LINE" inputs on channels 11-12.
• Multi-Zone Installation #2 (Diagram 6): Enables listening to different audio signals in each zone independently, utilizing a multi-zone preamplifier or up to six independent preamplifiers. The Input Selection switch on each channel is set to "LINE".
• Home Theater / Multi-Room Installation (Diagram 7): Accesses sources connected to a home theater receiver for multi-room use, relying on the receiver's multi-room output. Input Selection switches are set to "BUS" with adjacent channels assigned left and right.

Installation Considerations

DO:

• Place the amplifier on a solid, flat, level surface using its feet.
• Ensure the amplifier is in a well-ventilated area for proper cooling. Consider small fans for tight cabinets or racks lacking ventilation.

DON'T:

• Block ventilation holes on the top or bottom of the amplifier.
• Place the amplifier on carpeting or similar materials.
• Position the amplifier other than horizontally with feet down; avoid placing it on its side or back where terminals are located.
• Place the amplifier near heat sources or in areas exposed to moisture.

YOU SHOULD KNOW:

• The amplifier's large power supply may cause a hum in nearby components if placed too close.

Installation

CAUTION: All connections and switching must be performed with the amplifier's master power switch in the "off" position.

Select the Power Mode Selection:

Choose the appropriate power mode based on your installation needs. Set the switches as follows:

Selecting Inputs

Each channel can receive input from BUS, AUX, or LINE IN. Use the "BUS-AUX-LINE" Input Selection switch:

1. Select the desired source input: BUS (for BUS INPUT), AUX (for AUX INPUT), or LINE (for LINE IN).
2. For BUS and AUX inputs, use the "R R+L L" switch to select the right channel ("R"), left channel ("L"), or combined right and left channels ("R+L").

Selecting Bridge Mode

To combine two channels into one mono channel for increased power:

1. Ensure the Impedance Switch is set to the 8-ohm position.
2. Move the "BRIDGE" switch to the "ON" position.
3. Connect the speaker to the terminals located under the "BRIDGED" text. Input selection and settings for bridged channels are controlled on the left channel. Do not connect more than one speaker to bridged outputs.

Control Output

The 12V output jack on the rear panel can activate compatible components when the amplifier is "on" or active. The voltage ceases when the amplifier turns off. Ensure the connected device accepts 12V DC at 150mA. Use a two-conductor plug for the 3.5mm jack, noting the tip is positive (+). Contact an authorized PYLEUSA dealer if unsure.

Connecting the Speaker Wires

CAUTION: Make connections only when the amplifier is turned off.

Use high-quality speaker cables. Banana plug outputs on the rear panel allow versatile speaker connections. Insert speaker wire or spade connectors into the binding posts and turn to tighten, or insert banana plugs.

Connecting the Line Level Audio Inputs

CAUTION: Make connections only when the amplifier is turned off.

Inputs can be connected via BUS, AUX, and LINE IN. Refer to System Design Examples for optimal connection choices.

Audio Outputs

Sources connected to "BUS" or "AUX" inputs can be forwarded to other components or amplifiers using the corresponding output sections. Standard audio patch cables can link these outputs to another amplifier's inputs. Up to 5 amplifiers can be daisy-chained.

AC Power

Connect the amplifier's AC cord to the rear receptacle and plug the 2-prong plug into a 120V 60Hz wall outlet.

CAUTION: Do not plug the amplifier into a preamplifier or receiver's switched outlet. For automatic turn-on with the preamplifier or receiver, use the voltage or audio turn-on modes.

Operation

Refer to Diagram 1 for component locations:

• Power Switch: Located on the front panel, this switch turns off all amplifier circuitry regardless of the selected turn-on mode. Refer to the "Power Mode Selection" section for details.
• Active LED: When illuminated, this LED indicates the amplifier is operating. Refer to the "Power Mode Selection" section for more information.
• Protection LEDs: When lit, these LEDs on the front panel indicate a fault (wiring, speaker, or amplifier) that has caused associated channels to shut down.
• Level Adjustment Knobs: Located on the back panel, these knobs adjust the output level for each channel, useful for matching system levels or limiting volume in specific areas like children's rooms.
