Overview: The JBL 104 Reference Monitors are designed to deliver crisp highs and rich bass with vivid detail and no coloration. Powered with a built-in 60W amplifier (30W for each monitor), the 104s are optimized for desktop placement, offering a smooth off-axis response and a wide sweet spot.
Enclosure: The 104 Reference Monitors feature a coaxially mounted 4.5" woofer and a 3/4" soft-dome tweeter housed in ported, compact enclosure that can deliver accurate frequency response, exceptional detail, and impressive off-axis performance. The enclosure's low-frequency port, in conjunction with the woofer driver, can deliver tight, punchy bass at a wide range of listening levels, without the need for a subwoofer.
Amplifier: The JBL 104 monitor set features an integrated 60 watt Class-D amplifier, delivering 30 watts to each speaker. The amplifier is housed in one speaker (Master Monitor) and includes an Extension Output set of spring-clip terminals for connecting and powering the second speaker (Extension Monitor).
Inputs/Outputs: The Extension Monitor includes a single set of spring-clip terminals for attaching speaker wire from the Master Monitor. All signal connections to the speaker pair are made at the Master Monitor which includes the following:
- Front Panel:
- Aux-Input: An 1/8" stereo input is provided for connecting a smartphone or portable media player directly to the front panel.
- Headphone: An 1/8" stereo headphone output is included. When a jack is plugged in to the headphone output, sound from both speakers will be muted.
- Volume: A front-panel rotary control adjusts the volume level for both monitors.
- Rear Panel:
- RCA: A pair of unbalanced stereo RCAs is provided for pre-amp level audio signals.
- 1/4": Two balanced 1/4" input jacks can be used for running line-level signals into the monitors. Each jack is labeled either Master or Extension and is used to provide a signal to that corresponding monitor.
- Extension Output: A pair of spring-clip terminals provides the output signal to the Extension Monitor.
