Related Questions and Answers

Q: 1. Does the Marantz power amplifier sounds like an amplifier with an equalizer?

A: The Marantz MM7025 provides power only, and would be paired with a preamplifier, which would have inputs for your components and equalization adjustments. The Marantz AV7706 11.2-Channel Network Preamplifier with HEOS, BH #MAAV7706 is an example of a preamp that would work well with this power amplifier.

Q: 2. Will this work for terminating Canare BCP-B53 BNC ends? Looks like the opening for crimping the pin is a little off the 0.0531" spec.

A: You need the Canare TCD-35CA Die Set for BCP-B53, RCAP-C3A and FP-C3 Connectors or crimping tool that matches.

Q: 3. When used in the bridged mode for mono, will the headphone output be mono as well?

A: When cue monitoring with headphones on the Samson Servo 120a, you will receive a stereo signal in the headphones.

Q: 4. i want to run 2 pair of bose 701's and need 2 sub outputs. is this the rec to buy??

A: No, you will be able to drive just one pair of the 701s with this amp, and there are no sub outs.

Q: 5. So, I have to ask - what is the difference between this stand and a standard mic stand? Realistically, it seems one could use any mic stand (table or floor) with a 3/8" thread. Thanks!

A: The base plate for this will have a better balance than a normal mic stand for the larger speakers like the xx4x and xx5x size speakers. The pole is thicker than a standard mic stand and has a locking pin as an added safety measure. A standard mic stand pole may not support the weight of these monitors. Microphone stands are not designed to support the weight of a monitor. They may easily tip or start to slide down

Q: 6. Can I hook an equalizer to the Marantz power amplifier?

A: Unfortunately newer Amplifiers (and Receiver Amplifiers) no longer offer the ability to connect a separate Equalizer like the older models. The current models no longer provide Input / Output ports for Equalizers.

Q: 7. Why is this Marantz amplifier so expensive and it does not even have decent 4ohm performance. A lot of metal though.

A: This amplifier is not a stock item, and it is currently selling for list price. It's not for everybody.

Q: 8. is the input power for the Rolls RA235 220Volts or 110 Volts or it works on both 110V /220 V?Please adviseBest regards

A: The Rolls RA235 is compatible with 120 VAC 50/60 HZ only.

Q: 9. the only review here said the height was too short ? how could that be if you can adjust them from 43 inches to 66 inches ? also can I use these stands with my 8331a's ?

A: This stand height is up to 5.5 ft. so is not a low profile stand.

Q: 10. Does the Marantz stereo power amplifier has a midrange sound control?

A: This power amp does not have tone control. A preamp would be paired with this amp, and provide for tone control.
