Frequently Asked Questions - AMP-2100-70 Crestron
What is the output power of the AMP-2100-70?
The AMP-2100-70 delivers 100 W RMS per channel into a 70V distributed audio system, for a total of 200 W RMS.
Can the AMP-2100-70 drive low-impedance speakers (e.g. 4 or 8 ohms)?
No, the AMP-2100-70 is designed specifically for 70V/100V distributed audio systems. For low-impedance speakers, consider the AMP-2100 (non-70V version).
How do I bridge the AMP-2100-70 for higher power?
The AMP-2100-70 does not support bridging mode. It is a dual-channel amplifier intended for independent zone amplification.
What input voltage does the amplifier require?
The amplifier operates on a universal power supply accepting 100-240 V AC, 50/60 Hz. It is compatible with most global power grids.
How do I connect the AMP-2100-70 to a DSP or mixer?
Connect your DSP or mixer output to the balanced XLR or barrier strip inputs. Use shielded twisted-pair cable for best noise rejection.
Does the AMP-2100-70 include built-in DSP?
No, the AMP-2100-70 is a pure power amplifier without DSP. For integrated processing, consider a Crestron amplifier with DSP or connect an external DSP.
What is the maximum input level?
The maximum input level is +20 dBu for balanced inputs. The gain is fixed at 29.5 dB (adjustable via internal trimmers if supported).
How do I adjust the gain on the AMP-2100-70?
Gain adjustment is done via rear-panel trim pots (one per channel) with a range of 0 to +6 dB above the fixed 29.5 dB.
Can the AMP-2100-70 be used in a 100V system?
Yes, the amplifier is designed for both 70V and 100V distributed audio systems. The output voltage is selectable via internal jumper settings (refer to manual).
How do I reset the amplifier to factory defaults?
To reset, disconnect power, press and hold the reset button (inside the ventilation slot) while reconnecting power. Hold for 5 seconds until the LED blinks.
