Introduction
Features
Easily Extend Your Existing Network and Audio Setup
The DCH-M225 Wi-Fi Audio Extender is a portable plug-in repeater that lets you extend an existing wireless network. It also
has the ability to stream your music library to anywhere within your extended wireless network. Tiny yet powerful, it supports
Wireless N speeds of up to 300 Mbps in a device that ts in the palm of your hand.
Compact, Convenient Design
The DCH-M225 ‘s compact design is ideal for use at home or a small oce, as it does not take up much space and is ready to
use by simply plugging it in. The repeater’s small form means it can easily be plugged into a power outlet without blocking
other outlets while its wall wart design saves you the hassle of dealing with a power cord. Its sleek, unobtrusive appearance
means it blends easily into the background.
Conveniently Stream Audio
Expanding your audio capabilities has never been easier with the help of the DCH-M225. With support for both DLNA and
AirPlay, simply plug in your speakers and you’ll be able to stream audio to anywhere within your wireless network. The Wi-Fi
WMM quality of service protocol ensures that you’ll have no issues with bandwidth when streaming audio and performing other
tasks such as surng the Internet, checking email, or online gaming.
Simple Setup
Through its easy-to-use web-based user interface, you can quickly and easily connect the DCH-M225 to an uplink router,
congure the extender wireless network, and manage the administrative settings. The setup wizard will even guide you through
the setup process, getting your extended wireless network up and running in no time.
* Maximum wireless signal rate derived from IEEE Standard 802.11n and 802.11g specications. Actual data throughput will vary. Network conditions and environmental factors,
including volume of network trac, building materials and construction, and network overhead, lower actual data throughput rate. Environmental conditions will adversely
aect wireless signal range.

Section 1 - Product Overview
What is a Wireless Extender?
The DCH-M225 acts as a repeater to extend the range of an existing wireless network to provide better signal for parts of
your home or oce that may have poor or no reception. Your existing wireless signal will be re-broadcast by the DCH-M225,
allowing you to reach the farthest corners of your home or oce . The extended network can simply use the same network
credentials as the existing network, or you can specify a dierent network name and password, giving you the exibility to
control network access.
This purpose of this product is to create a constant network connection for your devices. As such, it does not have a standby
mode or use a power management mode. If you wish to power down this product, please simply unplug it from the power
outlet.

Wireless Installation Factors
The Wi-Fi Audio Extender lets you extend the reach of your existing wireless network, allowing you to work wirelessly from
more places in your home or oce. Keep in mind, however, that the number, thickness, and location of walls, ceilings, or
other objects that the wireless signals must pass through, may limit the range. Typical ranges vary depending on the types
of materials and background RF (radio frequency) noise in your home or business. The key to maximizing wireless range is to
follow these basic guidelines:
1. Keep the number of walls and ceilings between the extender and other network devices to a minimum - each wall or ceiling can
reduce your adapter’s range by up to 98 feet (30 meters). Position your devices so that the number of walls or ceilings is minimized.
2. Be aware of the direct line between network devices. At a 45-degree angle, a wall that is 0.5 meters thick (1.5 feet) appears to be
almost 1 meter (3 feet) thick. At a 2-degree angle it can appear over 14 meters (45 feet) thick! Position devices so that the signal
will travel straight through a wall or ceiling (instead of at an angle) for better reception.
3. Building materials make a dierence. A solid metal door or aluminum studs may have a negative eect on range. Try to position
access points, wireless routers, and computers so that the signal passes through drywall or open doorways. Materials and objects
such as glass, steel, metal, walls with insulation, water (sh tanks), mirrors, le cabinets, brick, and concrete can degrade your
wireless signal.
4. Keep your product away (at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate RF noise.
5. If you are using 2.4 GHz cordless phones or X-10 (wireless products such as ceiling fans, lights, and home security systems), your
wireless connection may degrade dramatically or drop completely. Make sure your 2.4 GHz phone base is as far away from your
wireless devices as possible. The base transmits a signal even if the phone in not in use.
