Product information

Description

The Kramer Electronics 900N is a compact power amplifier for balanced or unbalanced stereo audio signals. It provides reliable local amplification with up to 8.4 watts RMS per channel into a 4 Ω load and supports RCA connections. The 900N operates with Class D efficiency and is designed for presentation rooms, multimedia setups and personal audio listening.

Advantages

Class D operation delivers high efficiency and reduced heat generation. The unit features a volume control knob and an On LED for straightforward operation. With a signal‑to‑noise ratio of 55 dB and total harmonic distortion around 0.5%, the amplifier maintains clear sound for compact systems. The Kramer TOOLS form factor allows three units to be mounted side‑by‑side in a 1U rack using the optional RK‑3T adapter.

Suitable for

  • Presentation rooms and conference spaces for local audio amplification
  • Multimedia setups in classrooms or meeting rooms
  • Personal audio playback from a PC, portable CD player or other RCA sources

Key specifications

  • Channels: 2.0 (stereo)
  • Output power: 8.4 W RMS per channel into 4 Ω (speaker output)
  • Peak power (advertised): 35 W per channel
  • Distortion: Total harmonic distortion ≈ 0.5%
  • S/N ratio: 55 dB
  • Inputs: RCA (supports balanced or unbalanced signals)
  • Controls: Volume knob, On LED
  • Form factor: Kramer TOOLS™ compact, rackable (3 units in 1U with RK‑3T)
  • Color: Black

How to use

Connect the source device to the amplifier using RCA cables, observing left and right channel connections. Connect the speaker outputs to speakers rated for the amplifier load (4 Ω recommended). Before powering on the 900N, turn the volume knob to minimum to prevent sudden loud output. Power on the unit, then adjust the volume to the desired listening level while monitoring sound quality.

Usage recommendations

For consistent performance, use speakers with appropriate impedance (4 Ω) and avoid driving the amplifier into clipping. If mounting multiple units in a rack, install the optional RK‑3T adapter and leave adequate ventilation around each unit to ensure cooling.

Audio

Signal-to-Noise Ratio (SNR): This is the ratio of signal intensity to noise intensity.
55 dB
Total Harmonic Distortion (THD): Total harmonic distortion is a measure of non-linear harmonic distortion and is given in %. Non-linear harmonic distortions are signals which were not present in the original before the signal was converted by the headphones. These unwanted signals are caused by the diaphragm, whose movements do not precisely move in time with the electric signals that cause it to move. Unfortunately, this is a feature of all electroacoustic transducers. Although it cannot be completely eliminated, suitable steps can be taken to minimise it. However, the user is not interested in why this distortion takes place but in how great the level of distortion must be for it to become perceptible. According to the findings of several research projects, a total harmonic distortion of 1% in the frequency range of 100 to 2000 Hz is imperceptible. Below 100 Hz, the perceptibility threshold lies at 10%.
