Description
Amplifiers today need to be multi-faceted to keep up with the task at hand, and versatility is the foundation upon which the Dayton Audio APA150 is built. When configured in stereo mode, amplification is provided to a pair of speakers for stereo or surround playback. Select bridge-mono mode and the APA150 is ready to power a center channel speaker, or a subwoofer/tactile transducer when used with the on-board low pass filter. Full-range line-level outputs allow for daisy chaining amplifiers for a multi-room whole house audio system or for bi-amp applications. The APA150's smaller chassis consumes less space than conventional amplifiers, making placement options virtually limitless.
Highlights
- Sleek modern design looks good and sounds great
- Virtually noise-free fan operation for near field applications
- High current, discrete output transistors that run cool and quiet
- Adjustable 50 - 150 Hz low pass crossover gives you the room control you need
- Gold-plated 5-way binding posts that accept up to 8 AWG wire
Item is open and box and may be missing some internal packaging. Item will include original box.
BIG-AMP Features Packed Into a small-amp Chassis
Key features of the APA150 include high current, discrete power transistors (used in premium amp designs), a hefty toroidal power supply transformer, low-noise forced air cooling, a fully adjustable—and defeatable—electronic 50-150 Hz low-pass filter (18 dB/octave), and complete protection against electrical shorting and thermal overload. Also included are auto-on/off, silent turn-off with no audible transient, gold plated RCA inputs/outputs, and 5-way binding posts.
Features and Specifications: • Measured power output: 2 x 75 watts RMS (into 4 ohms @ less than 0.01% THD) • Signal-to-noise ratio: greater than 100 dB • Low pass filter: 12 dB butterworth • Class A/B design topology • Input sensitivity: 1V • Input impedance: 47k ohms • Auto-on sensitivity: 3 mV • Voltage requirement: 120/230 VAC, 60/50 Hz • Dimensions: 5.6" H x 5.7" W x 12.8" D.
Connecting the APA150
Connecting a line-level device
1. Locate the RCA line-level output from your source device.
2. Using RCA patch cables, connect the appropriate channel from the source output to the amplifier input.
3. For a mono line-level signal, use the left-level input.
Daisy-Chaining APA150s
1. Connect the line-level input from source device as above.
2. Connect the line-level output from first amplifier to line level input on the second amplifier.
Using the APA150s Low-Pass Filter
1. Ensure Low Pass-Flat switch is set to Low Pass.
2. Connect line-level input from source device.
3. Connect loud speakers as described below.
4. Adjust crossover frequency until desired output is reached.
Connecting Your Loudspeakers for Stereo Operation
1. Ensure that the amplifier is powered down.
2. Remove approximately 1/2" of the insulation from your speaker cables' positive and negative conductors.
3. Loosen the speaker binding posts by turning the knobs counter-clockwise, exposing the wire insert hole.
4. Observing polarity, insert the conductors into their appropriate binding posts and tighten the knobs down, securing the conductors in place.
Connecting Your Loudspeakers for Bridged-Mono Operation
1. Set the Mono-Stereo switch to Mono position.
2. Remove approximately 1/2" of insulation from your speaker cables' positive and negative conductors.
3. Loosen speaker binding posts by turning the knobs counter-clockwise, exposing the wire insert hole.
4. Connect positive conductor to top left binding post.
5. Connect negative conductor to bottom right binding post.
