Frequently Asked Questions - Vector CD896 Crestron

How do I configure the CD896 for low impedance operation?

Set the channel mode DIP switch on the amplifier to Lo-Z. Ensure the amplifier is powered off before changing any DIP switch settings.

What is the recommended gain setting when using a Crestron Avia DSP?

Crestron recommends a gain setting of 26 dB on the amplifier for optimal gain staging with Avia DSPs.

How can I avoid clipping the loudspeaker?

Ensure the amplifier's maximum power matches or exceeds the speaker's power rating. Set the DSP's Maximum Output Level higher than the amplifier's Maximum Input Level so the amplifier distorts before the DSP.

Can I use the CD896 in a bi-amplified setup?

Yes, the CD896 supports bi-amplification using two amplifier channels per speaker. The NL4 connector's pair #1 powers the low-frequency transducer and pair #2 powers the coaxial transducer.

What type of connectors does the CD896 use?

The speaker uses Neutrik speakON NL4 connectors. Each speaker has two NL4 connectors wired in parallel for pass-through to additional speakers.

How many CD896 speakers can I connect to a single CA-PWRSFT-1604 amplifier?

Up to 2 speakers per amplifier in non-bridged mode (one per channel).

How do I enable the high-pass filter?

Use the DIP switches on the rear panel of the amplifier. Refer to the product manual for exact DIP switch positions. Always power off the amplifier before changing DIP switches.

What is the difference between single amplification and bi-amplification?

In single amplification, one amplifier channel drives the entire speaker. In bi-amplification, two amplifier channels separately power the low-frequency and coaxial transducers for improved performance.

Where can I download the Avia channel strips for the CD896?

Download them from the Crestron website: Vector Output Strips for Avia DSP.

Can I bridge the amplifier for use with a subwoofer?

Yes, the CA-PWRSFT-1604 can be bridged to drive a single subwoofer. Use the bridged output connection diagram provided in the user manual.

USER MANUAL Vector CD896 Crestron

Crestron Performance Audio Systems: Powersoft Amplifiers

Powersoft Duecanali and Quattrocanali power amplifiers—CA-PWRSFT-1604 and CA-PWRSFT-2404, respectively—are designed to meet the high-power requirements of large audio systems. Both amplifiers offer a range of applications from basic background music and paging, to larger sound reinforcement systems in auditoriums, meeting places and other large gathering spaces.

These amplifiers are extremely versatile and may be used in low impedance performance systems. The compact, 1 RU housing and supplied mounting rails for 19" racks simplify installation while addressing space concerns. For high-impedance distributed systems, refer to Application Note (Doc. 8371) at www.crestron.com/manuals.

For additional amplifier wiring and operational details, refer to the CA-PWRSFT-1604 and CA-PWRSFT-2404 product manual at www.crestron.com/manuals.

Connections

To accommodate a variety of applications each amplifier includes several terminal block connectors. Depending on the attached loudspeaker, additional connectors may be required for terminations at the loudspeaker end.

Configurations

Each channel on a Powersoft amplifier can be independently configured for high-impedance (Hi-Z) distributed systems or low-impedance (Lo-Z) operation.

The amplifiers are configured for operations using DIP switches on the rear panel. Additional DIP switches configure High-Pass Filters (HPF) on each channel.

WARNING: To prevent damage to system components, ensure that the amplifier is powered off prior to changing any DIP switch setting.

NOTE: Refer to the product manual for details on wiring and additional DIP switch configurations.

Select Low Impedance Operation

All amplifier channels are factory-configured for Lo-Z operation. Additionally, the high-pass filter is disabled (HPF Off) and the gain is set to 32 dB. To set a channel for low-impedance operation, the channel mode switch must be set to Lo-Z.

Set Gain

The CA-PWRSFT-1604 and CA-PWRSFT-2404 have four amplifier gain settings. The gain level is set from the GAIN section of the CONFIG DIP switches.

Depending on the capabilities of the

headend equipment driving the amplifier, you may choose to modify the amplifier's input sensitivity.

Most contemporary audio systems include a DSP upstream of the amplifier input. The DSP's analog output gain settings are configured to achieve operational levels aligned with amplifier gain to prevent the DSP or amplifier from distorting the signal.

The amplifier should have sufficient Maximum Power per channel to meet or exceed the loudspeaker's power rating.

Using an amplifier that is too underpowered relative to the loudspeaker's power handling capacity may result in a clipped signal. A clipped signal creates harmonics, or DC voltages, that may cause damage to connected loudspeakers or other equipment.

To avoid clipping, set the DSP's Maximum Output Level to a level that is greater than the amplifier's Maximum Input Level. In this case, the amplifier would distort before the DSP's digital-to-analog converter is overdriven.

A good system design requires system components configured for optimum gain when feeding the next component downstream (also known as gain staging). When configured correctly, this ensures that the complete signal path from acoustic input at the microphone-to-loudspeaker output (also known as the system gain structure) is optimized.

To optimize gain staging with the amplifier, the Crestron Avia™ Audio tool includes an Output Gain object with level control that configures the digital level feed to the D/A converter. An analog gain control is provided after the D/A converter for Full Scale (FS) output to drive the amplifier input.

Crestron recommends a gain setting of 26 dB when using Crestron Avia DSPs. Additional amplifier gain settings are shown below for use with other DSPs.

There are many systems configurations available using the Crestron Avia Audio tool, Powersoft amplifiers and Vector Loudspeakers. Depending on requirements for channel assignments and amplifier loading, more complex systems are possible. As a general starting point in determining amplifier sizing and quantity for use with Vector loudspeakers, refer to the chart below with the loudspeaker use per amplifier.

All subwoofer references require the amp to operate with a bridged output; all other loudspeakers operate in a non-bridged configuration.
