FAQ

• Q: What is the purpose of the protection system in the amplifier?
• A: The protection system acts as a smart power regulator to extend component durability and maintain a high dynamic range when transducers operate in challenging conditions such as high excursion, temperature, or voltage.
• Q: What are the available input formats for the IMD16K Professional Amplifier?
• A: The inputs are available in both analog and AES formats, with AKM 96 kHz A/D converters for impressive encoding dynamics of 120 dB.

Overview

• Combining the excellent sound of Class AB and the power efficiency of the Class D amplifiers, TD Class technology allows lightweight amplifiers to deliver powerful and high-quality signals at the same time. In this amplifier the power supply tracks the audio signal at all frequencies, supplying the required rail voltage while at the same time reserving additional headroom. The superior efficiency reached by TD Class allows greater power density while minimizing cooling requirements, yet sound quality matches the best class AB design.
• The latest protection system carries out an advanced analysis of signal level. When transducers operate in the nonlinear domain, either at high excursion, high temperature or high voltage, the protection system acts as a smart power regulator to extend the component durability while maintaining the highest dynamic range.
• Inputs are available in analog and AES, and AKM 96 kHz A/D converters at the front end yield an impressive encoding dynamic of 120 dB. AES/EBU digital inputs operate with sample rate converters from 44.1 kHz to 192 kHz.

Technical Data

Overview of Connectors and Controls

front panel
The front panel LED area includes the following indicators per channel:

1. level control
   Calibrated potentiometers to alter the total gain of the power amplifier. To avoid distortions in mixing consoles upstream. these controls should normally be positioned between 0 and 10. The calibrated markings show the additional attenuation directly.

2. protect led
   When this LED is up during operation, one of the protection circuits against over-temperature, overload, shorted outputs, radio frequency interference, or DC faults has been triggered. The cause of the error e.g. shorted loudspeaker line must be remedied. In case of overheating, wait for a few seconds until the amplifier switches back to operating mode itself.

3. clip/limit indicator
   This indicator signal is on if the amplifier output is clipping or limiting. It has two different indication states: If the clip limiter is engaged, it has a short time constant, and it illuminates briefly. If the clip limiter is no engaged, it has an increased time constant, and it illuminates for a longer period.

4. sig/hi imp leg
   When the signal is green, it indicates normal operating range; when the signal is orange, it indicates high input impedance or open load.

5. power on indication
   This LED light is on when the mains switch is pressed. When not lit, the unit is not connected to the mains or the mains fuse has blown.

6. fan outlet grill
   The amplifier uses forced air cooling. Air is taken from the rear inlet and then excluded from the back. Do not obstruct the intake and exhaust ports.

7. power switch
   The unit is switched on via the power switch. The loudspeaker outputs are switched on via delayed relays so that no startup transients are audible. A current limiter prevents startup peaks on the mains line and prevents the mains fuse from blowing.

Stereo Mode
Before setting the mode. please turn off the amplifier and slide the mode select switch to the setup shown below. In this mode, Channel A and Channel B operate independently (just traditional stereo amplifiers). The signal input into channel A can be output from channel A only; similarly, the signal input into channel B can be output from channel B only.

Parallel Mode
Before setting the mode, turn off the amplifier. In parallel mode, turn on switch 9 as shown below (fig. 3). The green LED indicator is on, meaning the parallel mode is active. Input the channel signal from channel A. At this time, channel A and channel B have signal output, and the audio signal can control the volume separately. Similarly, turn on switch 10 as shown in fig. 4 below. The green light is on, meaning the parallel mode is active. Input the channel signal from channel C. At this time, channel C and channel D have signal output, and the audio signal can control the volume separately.

Audio input and output connections
Balanced input connections
The XLR in pul connectors are electronically balanced, and wircd according to the IEC 268 standard (pin 2 = hot). XLR inp u1 connectors should be wired as follows:

When linking the same source signal to several input channels, be aware that there is a limit to the number of channels an output source can drive. A typical output source (e.g. a DSP crossover unit) can drive up to two amplifier channels before external line drivers might be required to buffer the signal.

Unbalanced Input Connections

To connect an input to an unbalanced source, it is possible to connect pins 1 and 3 in the XLR plug at the amplifier end of the cable. However, a better method is to connect pin 3 to the shield at the source end of the cable, as this usually results in better hum and noise rejection. Balanced input connections are recommended whenever possible.

SpeakOn output connections
Refer to the instructions in this section if your amplifier is equipped with the Speakon output connectors.
