25V Transformer Wattage Taps

The SP-2570N provides the following selectable taps when connected to a 25V paging amplifier:

• 5W

• 2.5W

• 1.25W

• 0.625W

• 0.325W

This allows the installer to balance speaker output and amplifier capacity across a distributed paging system.

70V Transformer Wattage Taps

For 70V paging systems, available taps include:

• 5W

• 2.5W

• 1.25W

• 0.625W

• 0.312W

Multiple speakers can be connected to a compatible 70V amplifier as long as the total selected speaker wattage remains within the amplifier's rated output.

Direct 8-Ohm Connection

The SP-2570N can also be connected directly as an:

8-Ohm Speaker

The transformer can be bypassed when connecting to compatible Aiphone equipment or another audio source providing an 8-ohm speaker output.

Always verify the specifications of the connected equipment before using the direct 8-ohm connection.

Suggested Wattage Settings

Actual settings depend on the building acoustics, ceiling height, ambient noise, and desired volume.

Typical Aiphone recommendations include:

High-Noise Areas / 10'–12' Ceilings

2.5W or 5W

Suitable for:

• Warehouses

• Manufacturing facilities

• Large commercial spaces

• High ceilings

Offices / Drop Tile Ceilings

1.25W

Suitable for typical:

• Offices

• Classrooms

• Administrative areas

• Commercial spaces

Quiet Areas / Hallways

0.625W

Suitable for:

• Hallways

• Waiting areas

• Quiet office areas

• Low-ceiling spaces

Restrooms / Small Quiet Spaces

0.325W

Provides lower-volume paging without excessive sound levels.

Paging & Background Music

The SP-2570N is designed for both:

• Voice paging

• Background music

Its dual-cone speaker provides clear voice reproduction while maintaining a broad 65 Hz–17 kHz frequency response suitable for background music applications.

Compatible Aiphone Applications

The SP-2570N can be used with Aiphone systems that provide paging capability, subject to the output requirements of the specific system.

Applications include select:

• MC Series / MarketCom

• Intercom paging systems

• Commercial communication systems

• External paging amplifiers

• Aiphone paging adaptors

Always verify amplifier output impedance and system wiring before installation.

MarketCom Application

The SP-2570N is commonly associated with Aiphone's MC Series MarketCom communication and paging system.

Related MarketCom equipment includes:

• MC-60/4A – MarketCom Handset

• MC-A/A – Paging Adaptor

• MD35M – 35W Paging Amplifier

• MD60M – 60W Paging Amplifier

• MD120M – 120W Paging Amplifier

These systems can provide building-wide paging and background-music distribution through compatible ceiling speakers.

Optional SSB-3 Ceiling Support

For installations in suspended or drop-tile ceilings, Aiphone offers the:

SSB-3 – Ceiling Mount Support Bracket

The SSB-3 helps support the speaker assembly rather than placing the full load directly on the ceiling tile.

This accessory is sold separately.

Flush-Mount Installation

The SP-2570N installs flush into a compatible ceiling opening.

The finished installation leaves the 12-7/8" white round baffle visible, with only approximately 3/8" projection from the ceiling surface.

This provides a clean appearance suitable for commercial interiors.

Ideal Applications

• Commercial offices

• Schools and universities

• Healthcare facilities

• Government buildings

• Warehouses

• Manufacturing facilities

• Retail buildings

• Hallways

• Reception areas

• Paging systems

• Background-music systems

• Aiphone MarketCom installations

Important Installation Note

The SP-2570N is designed for indoor use only.

Before installation, verify:

• Amplifier output type

• 25V or 70V operation

• Required wattage tap

• Total amplifier wattage capacity

• Speaker quantity

• Cable requirements

• Ceiling support requirements

When multiple transformer-equipped speakers are connected to a paging amplifier, the combined wattage of all selected speaker taps should remain within the amplifier's rated capacity.
