KA-305 Household Power Amplifier 60W 4.1 Channel with Bluetooth and EQ for Home Audio

The KA-305 power amplifier is designed for home audio systems where you need reliable amplification for multiple speakers. With a 4.1 channel layout, it supports a centre channel and subwoofer output alongside left and right channels, giving you flexibility for music or movie sound. The built-in Bluetooth receiver lets you stream audio wirelessly from your phone or tablet, while the EQ equaliser allows you to adjust bass, treble, and midrange to suit different content. This amplifier works with standard passive speakers in the 4-16 Ohm range and provides 60W of rated power, making it a practical choice for living rooms, dens, or small home theatre setups.

Features and Construction

The KA-305 combines essential amplification functions into a single black chassis. Its interface and power options are designed to work with common home audio components, offering straightforward connectivity and flexible installation.

Amplifier Output and Channels

The amplifier delivers 60W rated power across four main channels plus a dedicated subwoofer output (4.1 channel configuration). This enables you to run a set of front and rear speakers alongside a subwoofer for enhanced low-frequency response. The amplifier handles speaker loads from 4 to 16 Ohms, accommodating a wide range of bookshelf and floor-standing speakers.

Connectivity and Controls

Input connections use Lotus (RCA) interface type, which is standard for consumer audio equipment such as CD players, TVs, and media streamers. The front panel includes controls for volume, input selection, and the EQ equaliser with sliders for adjusting frequency bands. Bluetooth connectivity is built in, allowing wireless pairing with smartphones, tablets, and computers.

Power and Voltage Options

The amplifier supports dual voltage input: AC220V for standard household mains in many regions, and DC12V for use with car batteries or other 12V DC power sources. This makes it suitable for both stationary home use and portable or vehicle-based setups. A power rating of 50Hz is specified for AC operation.

Uses and Placement

With its compact dimensions and versatile power input, the KA-305 can be integrated into various listening environments. Its 4.1 channel capability is particularly useful for home theatre or multi-room audio applications.

Home Entertainment System

Pair the amplifier with a set of passive speakers and a subwoofer to create a 4.1 surround sound system for TV, movies, or gaming. The Bluetooth input eliminates the need for long cable runs from source devices, and the EQ equaliser lets you optimise dialogue clarity or bass impact.

Music Listening Setup

For dedicated music listening, connect a CD player or streaming device via the Lotus inputs. The 20-20kHz frequency response ensures full audio range reproduction suitable for most music genres. The EQ controls allow fine-tuning to match speaker characteristics or room acoustics.

Vehicle or Mobile Use

The DC12V input option means the amplifier can be powered from a car's electrical system or a portable 12V battery. This makes it practical for mobile audio setups, outdoor events, or use in vehicles where you want to connect external speakers.

Benefits and Buying Value

The KA-305 provides straightforward amplification with modern wireless convenience. Its combination of channel count, power output, and dual voltage support offers flexibility without unnecessary complexity.

Flexible Power Options

Having both AC220V and DC12V input gives you the freedom to use the amplifier at home or on the move. This reduces the need for separate amplifiers for different environments and can be a cost-effective solution for multi-use scenarios.

Integrated Bluetooth and EQ

Built-in Bluetooth removes the hassle of connecting audio sources with cables, while the EQ equaliser gives you control over sound character. These features add convenience and customisation without requiring extra external components.

Simple Setup with Standard Connections

The Lotus (RCA) interface is a widely used standard, so you can easily connect existing audio equipment. The overall dimensions of L300 x W260 x H95mm mean the amplifier fits on a shelf or in a small AV cabinet without dominating the space.
