Palmer PBC400AA Rackmount Battery Charger
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.

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. 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 PBC400AA?
Typically used for audio equipment, PA systems, UPS sets, and other professional rack-mounted installations, the PBC400AA is a rack-mount battery charger made to charge 12V lead-acid batteries.
Q: How many batteries can the PBC400AA charge simultaneously?
Depending on the wire arrangement, it can charge up to four batteries at once while providing each cell with safe, controlled current.
Q: Can I leave batteries connected permanently?
Indeed. When connected for lengthy periods of time, the PBC400AA’s float charging feature safely preserves battery charge without overcharging.
Q: Can the charger overcharge the batteries?
No. To avoid overcharging and increase battery life, the PBC400AA has automated regulation and float charging.
Q: Can the charger be left unattended?
Yes, because of float charging and automatic control, but make sure you have enough ventilation and do regular inspections.
Q: Can the charger be used with a UPS or audio system simultaneously?
Indeed. As long as the overall load does not surpass battery limitations, batteries attached to the PBC400AA can power UPS systems, PA amplifiers, or other devices.
