Palmer Pan16 19“ DI-box, 8 channels passive
Introduction
A DI box is used to change an unbalanced, high-impedance signal to a balanced low low-impedance signal for connection to a microphone input. An unbalanced high-impedance cable routing is susceptible to hum and other noise. The cable length is limited because with longer cables, not only does the noise level rise, but due to cable capacitance, you can also expect a loss of highs.
These problems are avoided with low impedance balanced signal routing. For this reason, this type of routing is used almost exclusively in professional studios and for live performances. The PAN16 is a passive DI box that contains 8 independent channels in the 19“ format.
The DI box is constructed with the same circuitry design as our proven PAN01. The PAN16 is particularly useful when several signals must be balanced in one place at the same time, e.g., in the keyboard rack. Because the DI box is built as a passive device with high-quality transformers, no power supply is needed. Almost all sockets and switches are located on the front panel; only the XLR output jack and parallel LINK sockets are located on the rear panel.

Connections
The PAN16 has eight independent channels. The following description applies to each of the channels 1 – 8. Unbalanced instrument cables should not be longer than necessary. Therefore, the PAN16 should also be set up near the unbalanced source. The low impedance balanced output signal is available on the rear panel XLR/m socket. The assignment of the socket is standard, with a hot PIN 2. The connection to a mixer input is performed with a balanced, shielded microphone cable. The cable length is not critical and may be 100 feet or more, without an audible deterioration of the signal.
The Merge Links / In Function
Alternatively, the PAN16 also offers the possibility for the stereo signal, such as that of a keyboard, to sum to a mono signal and to direct it as a balanced mono signal to the PA system. The mono summed looped signal is present on the rear panel LINK socket.
Pad Switch
The PAN16 can also be used to feed speaker signals into a mixer. To do this, connect the amplifier output with the “Input” socket and loop the signal to the speakers via the “LINK” socket. Both cables must be speaker cables with an appropriate cross-section. A total of three attenuation levels are available: -10 dB, -20 dB, -30 dB (both PAD switches pressed down). To avoid clipping, the amplifier power should not exceed 100 watts
Gnd Lift Switch
This leads to grounding for these devices, and as a result, it may cause the so-called ground loop hum. But since it is sufficient to connect the ground on one side only for shielding purposes, the “GND LIFT” switch on the PAN16 enables the separation of PIN 1 from the ground.
This prevents ground loops and associated humming noises. In practical use, by trial and error, choose the position of the switch that causes the least noise.

FAQs
Q: What is the Palmer Pan16 DI-box?
Designed to transform high-impedance instrument signals into low-impedance signals appropriate for mixing consoles, audio interfaces, or PA systems, the Palmer Pan16 is a 19-inch, 1U rack-mounted passive DI (Direct Injection) box with 8 channels.
Q: What does “passive DI” mean?
A passive DI box employs transformers to convert signals and isolate ground loops, producing a clean, noise-free signal without the need for batteries or phantom power.
Q: Does the DI-box require phantom power?
No, the Pan16 doesn’t require phantom power because it is passive, but if the mixer or interface provides it, it can safely carry phantom power.
Q: Can I use the DI-box to reduce hum or ground loops?
Indeed. By separating the instrument from the mixer, the transformer-based passive design lessens ground loop interference, hum, and buzz.
Q: What is the frequency response of the DI-box?
Passive DI boxes, such as the Pan16, typically maintain the natural tone of the instrument by having a flat frequency response that is appropriate for audio transmissions between 20 Hz and 20 kHz.
Q: Can I use the Pan16 for line-level signals?
Yes, but to avoid overloading the transformer, you might need attenuation for high-output line-level signals. For this reason, certain passive DI boxes come with pad switches.
Q: Is the DI-box suitable for live performances?
Indeed. It is perfect for live performances, tours, or studio sessions because of its sturdy 19″ rack-mount architecture and transformer isolation.
