DA216S Distribution Amplifier

DA216S

The Rane DA216S Distribution Amplifier is a two-input, sixteen-output splitter/distribution amplifier. The DA216S is capable of providing sixteen discrete balanced outputs from one or two balanced mic-level or line-level inputs. The level of each output is individually adjusted via one of the sixteen screwdriver Output Level controls on the front panel. Each output may be assigned to either or both inputs via front panel accessible slide switches. Each output stage incorporates a high-current balanced output line driver for driving long lines with optimal performance.

The Master A and B Level controls affect the overall level of each input. In other words, they allow all assigned outputs to be turned up or down at once. LEDs indicate an Overload (OL) at either the inputs or at the internal gain stages.

Each input is set to either Mic or Line level via the rear panel Input Pad pushbutton. The separate Input Gain pushbutton switches provide a microphone input with +60 or +40 dB of gain, or a line input with +20 or 0 dB of gain. With Input Gain, Master Levels and Output Levels, any reasonable input signal may be adjusted to a nominal +4 dBu and still have 17 dB of headroom. The Phantom Power switch provides +15 VDC for condenser microphones. Any input assigned to line-level has this phantom voltage turned off automatically. A rear-panel LED indicates when the Phantom Power is engaged.

The DA216S improves on the previous DA 216 model with an internal universal voltage power supply, operable anywhere you can plug into 100-240 VAC.

DA216S Support

Is it possible to get mic level signals from the outputs?

Not without adding external pads. The DA216S outputs at line level so reducing the signal to mic level requires an outboard attenuator.

Where's unity gain on the DA216S?

With "Line" & "0" dB of gain selected on the rear, the front panel Input gain is unity at full clockwise. There is 10 dB of gain between this point and the output, so with the inputs set in this manner, the output trims are unity at 12:00 noon.

How about 32 unbalanced outputs?

The ("–") Output may also be used as an unbalanced line driver, albeit inverted. The balanced Input terminals of the next stage must be reversed (+) for (–) to correct for the inversion. This nets a total of 32 Outputs! However, the penalty for 32 outputs is that unbalanced operation will not drive long lines and individual control is lost.
