Key Specs
Continuous Watts x Channel @ Ohms: 40W x 12 x 4 ohms
Number of Channels: 12 (The number of discrete channels of sound output. This can be a single number or multiple numbers separated by decimal(s). The first number is the primary, horizontally directed audio channels. The number after the first decimal, if applicable, is the number of subwoofer outputs or channels. The number after the second decimal, if applicable, is the number of height or atmospheric channels designed to immerse the listener by producing overhead sound effects.)
General
Product Name: 12-Channel Power Amplifier
Brand: Niles
Model Number: SI-1230 SERIES 2
Color: Black
Audio
Continuous Watts x Channel @ Ohms: 40W x 12 x 4 ohms
Maximum Watts x Channel @ Ohms: 8-ohm configuration: 30W; 4-ohm configuration: 40W (This is the maximum load the speaker, subwoofer or amp can drive.)
Number of Channels: 12 (The number of discrete channels of sound output. This can be a single number or multiple numbers separated by decimal(s). The first number is the primary, horizontally directed audio channels. The number after the first decimal, if applicable, is the number of subwoofer outputs or channels. The number after the second decimal, if applicable, is the number of height or atmospheric channels designed to immerse the listener by producing overhead sound effects.)
Signal-to-Noise Ratio (SNR): 102 decibels (The ratio of the desired signal's strength to the level of background noise. A ratio higher than 1:1, which equates to greater than 0 decibels, indicates more signal than noise.)
Bass Boost: None (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
Inputs
Speaker-Level Inputs: true (Also referred to as high-level inputs. Enables the amplifier to receive a sound signal from another device that does not have RCA, or low-level, inputs.)
Line-Level Inputs: true (Also referred to as low-level inputs. Enables the amplifier to receive a sound signal from another device via RCA cables.)
Features
App Compatible: false (The product can be connected to a program or software application on a mobile device, which then receives collected data from the product.)
Bridgeable: true (Bridging an amplifier increases the power it supplies to the speaker(s).)
Dimensions
Product Height: 5.8 inches (The out of box height of the item. Height is measured as the vertical distance from the bottom of the item to the top as it would be primarily used or placed.)
Product Width: 17.25 inches (The out of box width of the item. Width is measured as the horizontal distance from one side of the item to the other as it would be primarily used or placed.)
Product Depth: 16.25 inches (The out of box depth of the item. Depth is measured as the distance from the front of the item to the back as it would be primarily used or placed.)
Product Weight: 35 pounds (The out of box weight of the item.)
This Niles power amplifier features 12 fully configurable channels and a BusMatrix selector to enable you to route your music to multiple speakers. The rack-mountable design provides flexible placement options to accommodate your audio setup.
480W total power (40W x 12 channels @ 4 ohms): 360W total power (30W x 12 channels @ 8 ohms) for powerful audio output.
BusMatrix selector: Enables each channel to select from left bus, right bus or left-plus-right bus options, or the channel's dedicated input to allow multizone use. PCB construction promotes high channel-to-channel isolation.
Metal film resistors, high-quality capacitors and oversize heat sinks: Ensure crystal-clear audio.
3 turn-on modes: Include music sense, voltage trigger and manual for ease of operation.
